Dissipative particle dynamics (DPD) simulations are used to investigate the effect of nanorods on the interface of immiscible A/B homopolymer blends. The nanorods are constructed by a string of beads connected through the spring forces, and then their rigidity is achieved depending on the angle forces. For the low volume fraction and/or aspect ratio, nanorods lead to broaden the interfacial width,...
A series of novel side-chain cholesteric liquid-crystalline elastomers based on polysiloxane and cholesterol derivate monomer were prepared by adopting a crosslinking agent containing binaphthalene group. The chemical structures and mesomorphic properties of the monomers and elastomers were confirmed by FT-IR, 1 H NMR, DSC and POM measurements. Worthily, the elastomers exhibited unusual temperature...
A new post functional strategy was developed to prepare polyphosphazenes with a high density of the indole based chromophore (nitro-indole or sulfonyl-indole chromophores) and carbazolyl side groups. Thus polyphosphazene (P1) with carbazolyl and indole groups was first prepared by direct nucleophilic substitution reaction with poly(dichlorophosphazene). Then, polyphosphazenes (P2–P4) containing charge-transporting...
