In polymer nanocomposites, the interfacial region plays a key role in the reinforcement of materials properties. Traditional two-phase micromechanical models usually ignore the contribution of such interfacial region to the overall materials properties. In this study, we use molecular dynamics simulation to determine the effective size and the Young's modulus of effective clay clusters which are regarded...
Honeycomb-patterned films can be facilely prepared by the breath figure method. However, it is still ambiguous how the polymer structure affects the morphologies of the films. In this work, poly(styrene-co-2-(2-,3-,4-,6-tetra-O-acetyl-β-d-glucosyloxy) ethyl methacrylate) (PS-co-AcGEMA) with well-defined linear and/or comb-like structures were synthesized by atom transfer radical polymerization (ATRP)...
Two series of biodegradable amphiphilic copolymers, poly(succinimide-co-N-propyl aspartamide) (PSI-PA) and poly(N-dodecyl aspartamide-co-N-propyl aspartamide) (PDDA-PA) were synthesized by partial and total aminolysis of polysuccinimide (PSI), respectively. PSI-PA copolymers could self-aggregate in water directly under ultrasonication at room temperature. Differing from PSI-PA copolymers, the aggregates...
