Synthesis and Application of Super-Soft Elastomers by Prof. Christopher M. Bates, U.C. Santa Barbara


Synthesis and Application of Super-Soft Elastomers

Prof. Christopher M. Bates

U.C. Santa Barbara, Materials Department

Tuesday, December 15,   Webinar 6:30 PM Pacific time


Traditional elastomers — for example, rubber bands and car tires — have an inescapable lower bound on stiffness that limits their performance in many advanced applications. My talk will discuss a relatively new class of materials known as super-soft elastomers that break this conventional paradigm in mechanical properties. We have developed simple synthetic strategies to create super-soft elastomers from easy-to-access molecular building blocks and versatile processing techniques to control physical properties and facilitate device integration. T he utility of this material platform is demonstrated by designing high sensitivity pressure sensors and new inks for extrusion-based 3D printing.

Speaker Background:

Christopher M. Bates earned a B.S. degree in Chemistry at the University of Wisconsin–Madison in 2007 and received a Ph.D. from The University of Texas at Austin in 2013 under the guidance of C. Grant Willson. After a postdoc with Robert H. Grubbs at the California Institute of Technology, Christopher moved to the University of California, Santa Barbara in 2016 as an Assistant Professor in the Materials Department.

Polymeric Materials for Additive Manufacturing (3-Day Live Virtual Short Course presented by Prof. T. Long, Arizona State University; Prof. C. Williams and Prof. M. Bortner, Virginia Tech)

Polymeric Materials for Additive Manufacturing

Presented by Prof. Timothy Long, Arizona State University; Prof. Christopher Williams, Virginia Tech; Prof. Michael Bortner, Virginia Tech

3-Day Live Virtual Short Course,

March 29 - 31, 2021

Sponsored by the Golden Gate Polymer Forum.


This three-day short course will be presented by recognized experts in the field of Polymer Science and Engineering at the interface of Additive Manufacturing (commonly termed 3D Printing). The course is designed to introduce scientists, engineers, or other professionals to basic principles, terminology, and applications of Additive Manufacturing (AM), with a focus on the use of polymeric materials in AM. The course will highlight the interplay of polymer material design, chemical reactivity, and rheology with the resolution and design aspects of resultant structures.

There will be an overview of the relevant polymer materials issues and structure-property relationships that are most important for various AM applications and technologies. A range of state-of-the art printing/process methods and modalities will be covered with an emphasis on extrusion, vat photopolymerization (VP), direct ink writing (DIW), material/binder jetting, and powder bed fusion (PBF).

No formal training or experience with AM is assumed or expected; some experience with polymer science and engineering would be helpful. The combination of an excellent team of cutting-edge researchers as instructors, an affordable price, and an emphasis on practical applications and rapidly emerging technologies makes this an exceptional opportunity. A course wiki site will be available with supplementary selected literature, and the site will remain open for a considerable time after the course to encourage interactive discussions regarding clarification of concepts, as well as to provide a source for additional information on specific course topics.

Topics Covered

  • Introductions to additive manufacturing processes, polymer rheology in AM processes, polymer terminology, and classes for AM
  • Rheology and extrusion-based AM
  • Thermoplastics structure-property relationships
  • Structure-property relationships of printed parts
  • Photochemical processes in AM, influence of light on viscoelasticity, and photo-reactive polymer design
  • Modeling photochemical processes
  • Powder bed fusion principles, thermal properties of polymers for PBF, and polymer design for PBF
  • Polymeric binders for jetting AM, material jetting processes, and introduction to solution rheology for jetting operations
  • Emerging topics in printing and AM, materials design for AM, and properties and performance of printed objects
  • Video tours of facilities, demonstrations, and highlights of industrial leaders
  • Relevant polymer characterization tools; fundamentals and applications, accelerating discovery of AM materials and processes
