Disclosing the formation of ring-banded spherulites for semicrystalline polymers through the double-layer film method
The formation of ring-banded spherulites in double-layer semicrystalline polymer films has seldom been
a concern. In this study, the nucleation and growth of ring-banded spherulites in poly(ethylene oxide)/poly(L-lactide) (PEO/PLA) double-layer films during isothermal crystallization at various temperatures above the melting point of the PEO layer have been investigated by using polariz...

Supercapacitor electrodes based on nano-polyaniline deposited on hollow carbon spheres derived from cross-linked co-polymers
Nano-polyaniline (nano-PANI) was deposited on hollow carbon spheres (HCS) to prepare nano-PANI/HCS
composites via in-situ chemical polymerization. The composites combined the high pseudocapacitance
of nano-PANI and the excellent porous structure of HCS which were prepared by the carbonization of a
cross-linked co-polymer, poly(styrene-co-divinylbenzene-co-methylacrylic acid). The struct...

Polymerizing Nonfluorescent Monomers without Incorporating any Fluorescent Agent Produces Strong Fluorescent Polymers.
All the fl uorescent polymers prepared via atom transfer radical polymerization (ATRP) or reversible addition-fragmentation chain transfer (RAFT) are those polymers that have been functionalized with fl uorophore. Prior to our study, it was generally believed that polymerizing nonfl uorescent monomer without incorporating any fluorescent agent only results in polymer without ...

(Chin.J.Polym.Sci.) Polysiloxane Side-chain Liquid Crystalline Polymers Prepared by Alkyne Hydrosilylation
We describe in this work an alkyne-hydrosilylation approach to synthesize a series of novel polysiloxane sidechain
LCPs attaching end-on or side-on mesogenic side groups. Their properties are characterized by NMR, FTIR, gel
permeation chromatography, thermogravimetric analysis, differential scanning calorimetry, polarized optical microscopy and small-angle X-ray scattering. These obtained alkenyls...

(Polym. Chem.) Poly(Vinyl Benzoate)-Backbone Mesogen-Jacketed Liquid Crystalline Polymers
Previously reported polymer backbone structures of mesogen-jacketed liquid crystalline polymers
(MJLCPs) are still limited to polyacrylate, polystyrene, polyacetylene, polysiloxane, polythiophene and
polynorbornene. In this manuscript, we describe a new system of MJLCPs with poly(vinyl benzoate)-
backbone (PVBnB), which were synthesized by solution polymerization and bulk photo-polym...

Shape-stabilized phase change materials based on poly(ethelyene-graft-maleic anhydrids)-g-alkyl alcohol comb-like polymers
In this study, a series of shape-stabilized comb-like polymeric phase change materials (CLPPCMs), denoted as EMA-g-CnH2n+1OH (poly(ethylene-graft-maleic anhydride)-g-alkyl alcohol) with n=14, 16, 18, 26, were prepared through an esterification reaction between poly(ethylene-graft-maleic anhydride) (EMA) and n-alkyl alcohols (CnH2n+1OH). The structure, thermal properties and shape-stabili...

[2015][Macromolecules, 2015, 48 (12), 3941–3948]Optimization of Broad-Response and High-Detectivity Polymer Photodetectors by Bandgap Engineering of Weak Donor–Strong Acceptor Polymers
A series of weak donor–strong acceptor polymers containing two different electron-deficient units (diketopyrrolopyrrole and thienoisoindigo) are synthesized and used in broad-response and high-detectivity polymer photodetectors. By adjusting the composition ratio of the two acceptors, the absorption spectra, energy levels, molecular stacking, and film morphology are affected, which in turn infl...

(Polym. Chem.) Side Chain Liquid Crystalline Polymers with an Optically Active Polynorbornene Backbone and Achiral Mesogenic Side Groups
This work describes series of side-on and end-on SCLCPs with an
optically active polynorbornene main chain and achiral mesogens. The side-on SCLCPs display the tendency of forming nematic,
i.e. achiral mesophases, in strong contrast with the chiral nematic phase exhibited by their comparative end-on analogues.

(Macromolecules) Polysiloxane-Based Liquid Crystalline Polymers and Elastomers Prepared by Thiol-Ene Chemistry
A series
of side-chain liquid crystalline polymers (LCPs) with polysiloxane backbones
have been synthesized by grafting mesogenic monomers to
poly[3-mercaptopropylmethylsiloxane] (PMMS) via thiol-ene click chemistry. Moreover, by controlling the molar ratio of PMMS and
mesogenic monomers, PMMS-based LCPs can be
partially functionalized, meanwhile leaving spare mercapto groups, which can be
fu...
