To discuss the factors that greatly affect the stabilization and destabilization of the conformation of lignin caused by changes in temperature and/or swelling, the temperature dependence of the loss tangent (tanδ) of the sample given the different cooling rates and the changes in the storage elastic modulus (E′) and the loss elastic modulus (Eʺ) over time during the swelling process were measured ...

To precisely control particle adhesion, we used nanoparticles with a core-shell structure, where the core is composed of polymethyl methacrylate and the shell is composed of a combination of polymethyl methacrylate and pol ...

Herein, we describe the solvent-free synthesis of shape memory PHU networks from diglycerol dicarbonate through reactive extrusion with varying amounts of primary and secondary triamines, tris(2-aminoethyl)amine and tris(2-(methyl ...

PLA and PMMA are miscible and the unique glass transition temperature can be easily controlled by a proper amount of PMMA according to Gordon-Taylor equation. Water penetration as well as phosphorus release was reduced wh ...

The well dispersed BNNSs-NH₂ in the blends was prepared by the urea-functionalization process, which built a bridge to each other at the interface between epoxy and PEI phases. The through-plane thermal conduc ...

Inspired by the dynamic nature of such bonding, we have developed a polyurethane equipped with dynamic urea bonds (PEDUB) that has high strength sufficient to make it be freestanding and have a healing capability and self-bonding property. This allowed subsequent heterogeneous multicompone ...
