Side-chain liquid crystal elastomers (SC-LCEs) have been designed by using a new smectic crosslinker. Two types of monodomain films were prepared based on polysiloxane chains, with different relative concentration both crosslinker and mesogenic comonomers. The mesomorphic behavior the two SC-LCE systems was investigated differential scanning calorimetry polarized optical microscopy showing beha...

An increasing interest in tunable photonic structures is growing within the photonic community. The usage of Liquid Crystalline Elastomer (LCE) structures in the micro-scale has been motivated by the potential to remotely control their properties. In order to design elastic photonic structures with a three-dimensional lithographic technique, an analysis of the different mixtures used in the mic...

Crosslinkers are indispensable constituents for the preparation of SPE materials with ethylene glycol dimethacrylate (EGDMA) and divinylbenzene (DVB) among most prominent representatives. A crosslinker that has not yet been used sorbents is 3,3’-(hexane-1,6-diyl)bis(1-vinylimidazolium) bromide [C6-bis-VIM] [Br]. In this study, we synthesized differently crosslinked vinylimidazole polymers EGDMA...

Abstract Hydrogel is a 3D framework of hydrophilic polymeric material that quickly absorbs and retains huge amount water (or other fluid) offers versatile functionality. A series unique carboxymethyl cellulose/Xanthan gum/polyvinyl alcohol (CXP) blended hydrogels, containing both the natural synthetic polymers, were prepared by following blending casting approach. The polymers incorporated thro...

The application of biodegradable chitosan fiber for healthy and hygienic textiles is limited due to its poor acid resistance in wet processing and poor antioxidant activity. In order to prepare chitosan fiber with good acid resistance and high antioxidant activity, chitosan fiber was first crosslinked by a water-soluble aziridine crosslinker, and then dyed with natural lac dye consisting of pol...

A chrome gel system with 13 million molecular weight and 19 polymer DQ-8 cross-linking agent is dynamically gelled under different conditions of 50-mesh 100-mesh screens shear rates. Concentration limit. The experiment shows that the critical concentration gelation 500-700mg/L, new in 80mg/L-90mg/L. cross-linker cut by steel mesh. post-gelation time prolonged. Between 6h-10h, after 12 days test...
