Microporous and Degradable Polymers for a Sustainable Future by Prof. Yan Xia, Stanford University


Microporous and Degradable Polymers for a Sustainable Future

Prof. Yan Xia

Department of Chemistry, Stanford  University

Thursday, October 27, Webinar at 6:30 PM Pacific time


Innovative polymer chemistry plays an important role in achieving a sustainable future. I will present two types of polymers my lab has developed toward this goal – enabling energy-efficient chemical separations and recyclable thermosets. The first type is microporous ladder-shaped polymers that function as size-sieving membranes for the separation of important gases with minimal energy consumption and environmental impact. We serendipitously discovered an interesting structure-dependent aging behavior for these polymer membranes – separation selectivity is increased considerably over time without losing permeability significantly. By tuning the polymer chain configurations, we have obtained mechanically robust membranes with an unprecedented combination of ultrahigh selectivity and permeability, setting record performance for many gas separations. The second type of polymer is degradable/recyclable thermosets based on dicyclopentadiene (DCPD) and cyclic enol ether. An overlooked reactivity of Grubbs catalysts allowed us to synthesize polyDCPD thermosets and composites with a wide range of remarkable mechanical properties, easy processibility, and on-demand degradability. I will present the enabling chemistry for these developments, optimization of material properties and performance, and paths toward real-world applications.

Speaker Background & Research Interests:

Yan Xia is an associate professor in the Chemistry department at Stanford University. He grew up in Beijing and received his undergraduate degree from Peking University ('02), MSc from McMaster University ('05), and PhD from Caltech ('10) all in Chemistry, where he was trained under the tutelage of Profs. Bob Grubbs (deceased) and Julie Kornfield. Following his PhD study, he took a well-paid “sabbatical” in industry to work at Dow Chemical as a senior chemist for one and a half years, but decided curiosity-driven rather than application-driven research is at his heart. He then quit the job and transitioned back to academia as a poor postdoc at MIT for a year. He was extremely fortunate to find a job at Stanford and opened his lab there in the chemistry department in the summer of 2013, and became a tenured member of the department in 2020 amidst all the chaos that year. His research interest lies in the design, synthesis, and manipulation of organic materials and polymers. His research group leverages a range of unusual molecular structures and overlooked reactivities to develop innovative soft materials.

Polymers For Medical Applications (2-Day Live Virtual Short Course by Dr. Subbu Venkatraman, UC San Diego)

Polymers For Medical Applications

A two-day overview of polymeric families and how they are used to treat and diagnose disease

Presented by Dr. Subbu Venkatraman, Innovations Manager, UC San Diego

2-Day Live Virtual Short Course,

November 2 and November 4, 2022 (Wednesday, and Friday)

Sponsored by the Golden Gate Polymer Forum.

Course Overview

Polymers are increasingly finding use in medicine. Natural, synthetic, and biomimetic polymeric materials will be discussed in the context of the key role they play in advancing medical device technologies. Applications where polymers play a key role include (but are not limited to) biosensing, tissue replacement/repair, drug delivery through the oral and transdermal routes, gene delivery using nanoparticles, and Covid-19 vaccines

This two-day virtual course will address the breadth of different polymeric systems in a wide range of usage areas from medicine and drug delivery to medical devices. Attendees will get an overview of how to evaluate the many medical needs that can be addressed by clever use of polymers. Key takeaways from the course should include: an understanding of which medical devices are functionally dependent on the performance attributes of the polymers used; aspects of designing polymers for specific medical applications including device coatings and use of biomimetic polymers; how to evaluate the merits of using synthetic polymers over naturally-derived polymers for implanted devices; and assessing the ability to modify polymers to enable biodegradable and biostable coatings on devices.


Specific Topics Covered

Introduction to Polymers for Medical Applications; Biocompatibility 

  • Integration of polymers with surrounding tissue; cytotoxicity

Gels, Crosslinked Systems and Stimuli-responsive Hydrogels

  • Applications: contact lenses, adhesives in patches; triggered drug delivery

Drug/Protein/Gene Delivery; Nanostructured Polymers

  • Self-assembly; nanocarriers for siRNA and mRNA; COVID-19 and other vaccines

Natural Polymers and Biomimetic Polymers

  • Proteins; artificial proteins; biomimetic polymers/proteins; collagen, elastin

Biodegradable Polymers

  • Sutures; fully-degradable implants; biocompatibility of degradation products

Tissue Engineering Scaffolds and Device Coatings

  • Tissue compatibilization using coatings; functionalized surfaces that help to integrate implants; blood-contacting devices; artificial blood vessels; bio-artificial pancreas

Who should attend:

This course is likely to be of particular interest to scientists and engineers in medical device industries as well as in biotech companies involved in drug or gene delivery/ vaccines/nanomedicine. People working (or desiring to work) in any function that involves polymeric materials (R&D, Design Engineering, Manufacturing, Quality, Reliability, Materials Procurement, Regulatory Compliance, etc.) but who have not had directly relevant polymer science training are highly likely to benefit. Please note that some familiarity with chemical nomenclature and structure will be helpful, but a degree in chemistry is not a requirement to benefit significantly from this survey course.

Instructor Background

Dr. Subbu Venkatraman has a PhD in Polymer Chemistry from Carnegie-Mellon University.

Dr. Venkatraman spent about 15 years in materials and biomedical R&D in the USA, working with various applications of polymeric materials, before joining the Nanyang Technological University (NTU) in Singapore as an Associate Professor in 2000. He was instrumental in starting the Biomaterials effort at NTU and developing the paradigm of research driven by medical needs. He served as Associate Chair for Research in the Department of Materials Science and Engineering for 6 years, before taking over as Chair in 2011. Under his watch the School's worldwide ranking jumped 41 places to #3 as per the QS rankings, and #1 as per the US News & World Report rankings.

Dr. Venkatraman has published extensively in the field of biomaterials, with a total of 270 publications, with an H-index of 47 and a citation count of 10,000. He also holds 70 patents from a total of 171 applications. His work in biomaterials has led to 3 spin-off companies, with one of them (Amaranth Medical) obtaining substantial series C funding. He has also received the 2014 Singapore President's Technology Award together with Professor Freddy Boey and Adjunct Professor Tina Wong, for their innovative application of nanostructures and novel drug delivery approach to combat blindness from glaucoma. He is also the co-founder of Peregrine Ophthlamic Pte Ltd and Amaranth Medical Pte Ltd.

Dr. Venkatraman's National University of Singapore (NUS) research group was most recently interested in designing and modifying materials for biomedical applications, with a focus is on nanotechnological approaches to enhance the efficacy of protein drugs and genes. Today, he is the Innovations Manager for the U.C. San Diego School of Medicine.
