Molecular Recognition in a Thermoplastic Elastomer

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...

Thermal and Morphological Properties of Thermoplastic Elastomer Nanocomposites Based on PA6/NBR

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...

Molecular recognition in bisurea thermoplastic elastomers studied with pyrene-based fluorescent probes and atomic force microscopy.

Fluorescence spectroscopy and atomic force microscopy (AFM) measurements using bisurea-pyrene probes show that they are randomly dispersed in the hard blocks of thermoplastic elastomers with matching bisurea groups, whereas they phase separate from polymers with non-matching or no bisurea groups.

Supramolecular thermoplastics and thermoplastic elastomer materials with self-healing ability based on oligomeric charged triblock copolymers

Supramolecular polymeric materials constitute a unique class of materials held together by non-covalent interactions. These dynamic supramolecular interactions can provide unique properties such as a strong decrease in viscosity upon relatively mild heating, as well as self-healing ability. In this study we demonstrate the unique mechanical properties of phase-separated electrostatic supramolec...
