Aplicación

The Progress in Development of Dental Restorative Materials
Pentaerythritol tetrakis(3-mercaptopropionate) can be used as a precursor to synthesize:
  • Polymeric degradable networks through thiol-ene click reactions with tri/tetra-acrylates.
  • Thiol-ene-methacrylate composites, which are applicable as dental restorative materials.
  • Network solid polymer electrolytes based on polydimethylsiloxane, for lithium-ion batteries.
It can also be used to functionalize poly(high internal phase emulsions) for removal of heavy metals from water.

We report the development and characterization of digital microfluidic (DMF) immobilized enzyme reactors (IMERs) for studying cytochrome P450 (CYP)-mediated drug metabolism on droplet scale. The on-chip IMERs consist of porous polymer (thiol-ene) monolith plugs prepared in situ by photopolymerization and

This study presents the first direct comparison of the influence of liquid-crystal order during synthesis on the thermo-mechanical behaviors of main-chain liquid-crystal elastomers (LCEs) in thiol-acrylate networks. Six polydomain nematic elastomer (PNE) chemistries were compared directly by synthesizing with the
