CHEMISTRY
Recovery of monomer from polyurethane materials by depolymerization

Methods for recovering monomers from polymers, such as polyurethanes (including thermoset polyurethanes) include heating the polymer to depolymerize the polymer and release the monomer. The monomer may be directly recovered. The polymer may include a poly(.beta.-methyl-.delta.-valerolactone) (PMVL) block and the monomer recovered may be...

Conductive elastomer composites based strain sensors have attracted increasing attention recently. In this paper, flexible composites were prepared by incorporating thermoplastic polyurethane (TPU) with zero-dimensional carbon black (CB) and one-dimensional carbon nanotubes (CNTs), respectively. CNTs/TPU showed a lower percolation threshold (0.28...
