Feb Dinner Prof. Moore


The Golden Gate Polymer Forum Feb 2007 Dinner Lecture
    Wednesday, Feb. 21
    Michael's Restaurant at Shoreline Park, Mountain View

The GGPF welcomes Prof. Moore to speak for us after attending the Asilomar Conference on Fuel Cells:

"Anisotropic Actuation in Nanostructured Ionic Polymer Metal Composite (IPMC) Artificial Muscles"                 

                Dr. Robert B. Moore
                Professor of Polymer Science and Engineering
                The University of Southern Mississippi


Ionic polymer-metal composites (IPMCs) are a subclass of electro-active polymers bearing surface electrode layers consisting of conductive nanoparticles distributed within an ionic polymer matrix.  With the application of electrical stimulation, ions and solvent molecules are proposed to migrate resulting in pressure gradients that induce an actuation response.  Specifically, IPMCs are known for potential applications as artificial muscles and robotic actuators.  Recently, we have demonstrated that the nanostructured ionic polymer matrix plays an important role in the resulting actuation behavior.  For example, the organization of the ionic domains may be tailored by the application of uniaxial extension during membrane processing to yield fibrilliar morphologies.   In a bio-mimetic fashion, this anisotropic, nano-scale organization of the ionomer membrane may be established in order to generate anisotropic actuation behavior in artificial muscle
applications.  Moreover, these morphological manipulations may be exploited to provide fundamental information related to the actuation mechanism in these stimuli-responsive materials.  Based on fundamental information from neutron imaging experiments, we will
demonstrate that a key contribution to the actuation mechanism in these systems is attributed to a water gradient created along the membrane cross-section in response to the applied electrical stimuli.  Anisotropic actuation in the oriented IPMCs will be discussed in terms of the importance of morphology in the overall behavior of these materials.

       Speaker Background:
Robert B. Moore is a Professor of Polymer Science and Engineering at the University of Southern Mississippi.  He received his Ph.D. in Analytical Chemistry from Texas A&M University under the direction of Professor Charles R. Martin, followed by a two-year post doctoral research appointment in the Department of Chemistry at McGill University in Montreal, Quebec under the direction of Professor Adi Eisenberg.  He joined the faculty of the Department of Polymer Science at The University of Southern Mississippi in 1991.  Professor Moore’s current research interests include:  nanoscale characterization of morphological and physical property modifications of semicrystalline
polymers via the incorporation of small quantities of ion-containing onomer units; control of morphology-transport property relationships in PEM fuel cell systems via tailored processing procedures and controlled molecular/supramolecular architecture; characterization and control of actuation behavior in nanostructured ionic polymer metal composite (IPMC) artificial muscles; the use of small-angle x-ray and neutron scattering methods for the characterization of morphology and dynamics in nanostructured materials; and polymer-based nanocomposites for improved chemical and physical properties.
