Thermoplastic Elastomer Prepared by Dynamic Vulcanization.

Effect of Rubber Nanoparticle Agglomeration on Properties of Thermoplastic Vulcanizates during Dynamic Vulcanization

We previously reported that the dispersed rubber microparticles in ethylene-propylenediene monomer (EPDM)/polypropylene (PP) thermoplastic vulcanizates (TPVs) are actually agglomerates of rubber nanoparticles. In this study, based on this new understanding of the microstructure of TPV, we further revealed the microstructure-properties relationship of EPDM/PP TPV during dynamic vulcanization, es...

Enhanced Coarse-Graining of Thermoplastic Polyurethane Elastomer for Multiscale Modeling

The objective of this work is to develop a multiscale modeling tool of copolymers with long chains. We propose an enhanced coarse-graining method of thermoplastic polyurethane (TPU) with three beads. The proposed coarse-graining provides an accurate molecular modeling tool to keep the molecular interaction together with computational efficiency. The coarse-grained model with three beads is furt...

Mechanical and Electrical Properties of Sulfur-Containing Polymeric Materials Prepared via Inverse Vulcanization "2279

Recently, new methods have been developed for the utilization of elemental sulfur as a feedstock for novel polymeric materials. One promising method is the inverse vulcanization, which is used to prepare polymeric structures derived from sulfur and divinyl comonomers. However, the mechanical and electrical properties of the products are virtually unexplored. Hence, in the present study, we synt...

High-throughput Fabrication of Advanced 3d Microfluidic Devices in Thermoplastic Elastomer for Biological Probe Immobilization

We have developed a process based on hot-embossing lithography (HEL) to pattern at high-throughput micron-size through-holes in thin thermoplastic elastomer (TPE) membranes. This novel HEL process, which is shown to provide key advantages for microfluidics applications, was applied to the fabrication of highly-integrated 3D microfluidic devices designed to precisely immobilize biomolecules on t...
