Chain Folding in Main-Chain Liquid Crystalline Polyester with Strong π–π Interaction: An Efficient β-Nucleating Agent for Isotactic Polypropylene
本论文通过分子设计合成了一种液晶聚酯，其侧基苯环错位平行堆积形成强烈的物理ππ相互作用，更重要的是，这些错位平行堆积的苯环结构与聚丙烯β晶型的晶胞参数c轴匹配。将其与聚丙烯共混，可以在静态结晶条件下诱导聚丙烯附生结晶完全形成β晶型。这是目前文献报道中β晶型诱导效率最高的大分子成核剂，这项工作的开展将为新型高效聚丙烯β成核剂的开发提供一种新的思路。

(Polym. Chem.) A Room-Temperature Two-Stage Thiol-Ene Photoaddition Approach towards Monodomain Liquid Crystalline Elastomers
Monodomain liquid crystalline elastomers (LCEs)
with anisotropic, loosely crosslinked polymeric matrices, have attracted intense scientific attention due
to their widespread applications in stimuli-responsive soft actuators.
However, traditional synthetic pathways towards monodomain LCEs require complicated
procedures, elevated
reaction temperatures, and p...

【ACS Applied Materials & Interfaces】Liquid-infused poly (styrene-b-isobutylene-b-styrene) microfiber coating prevents bacterial attachment and thrombosis
Abstract:
Infection and thrombosis associated with medical implants cause significant morbidity and mortality worldwide. As we know, current technologies to prevent infection and thrombosis may cause severe side effects. To overcome these complications without using antimicrobial and anticoagulant drugs, we attempt to prepare a liquid-infused poly(styrene-b-isobutylene-b-s...

(Polym. Chem.) An Entropy-Driven Ring-Opening Metathesis Polymerization Approach towards Main-Chain Liquid Crystalline Polymers
The known synthetic methods of preparing main-chain liquid crystalline polymers (MCLCPs) are rather limited to several polycondensation reactions. However, the nature of step-growth polycondensation endows the corresponding MCLCPs with relatively low molecular weights and broad molecular weight distributions. In this manuscript, an entropy-driven ring-opening metathesis polymerization (ED-ROMP) ...

(Liq. Cryst.) Photo-Responsive Polysiloxane-Based Azobenzene Liquid Crystalline Polymers Prepared by Thiol-Ene Click Chemistry
In this work, a novel polysiloxane-based azobenzene-containing liquid crystalline polymer (LCP) PMMS-A44V6 are designed and synthesized via a facile thiol-ene click chemistry method by grafting a side-on azobenzene mesogenic group A44V6 onto poly-[3-mercaptopropylmethylsiloxane] (PMMS) backbone. 1H NMR, 13C NMR, GPC, TGA, DSC, POM and WAXS are used to investigate the mesogenic properties and photo...

(Macromolecules) Near-Infrared Responsive Liquid Crystalline Elastomers Containing Photothermal Conjugated Polymers
In this work, we report the ?rst example of uniaxial aligned conjugated polymer (CP)/liquid crystalline elastomer (LCE) composite material by doping polyaniline nanoparticles into a classical monodomain polysiloxane-based LCE matrix. A series of comparative experiments are performed to investigate the photoresponsive properties of these polyaniline/LCE samples in correspondence to the two di...

(Chemical Science) A calamitic mesogenic near-infrared absorbing croconaine dye/liquid crystalline elastomer composite
In this work, we report the first example of a calamitic mesogenic near-infrared (NIR) absorbing organic dye,
made by functionalizing a thiophene–croconaine chromophore rigid core with two symmetric long flexible
alkyl chains. The liquid crystal (LC) NIR dye YHD796 exhibits a sharp and intense NIR absorption band with
a maximum absorption peak at 796 nm. Taking advantage of the improve...

(Chem.Commun.) Homeotropically-Aligned Main-Chain and Side-on Liquid Crystalline Elastomer Films with High Anisotropic Thermal Conductivities
In this
work, we synthesize nematic main-chain and side-chain
side-on crosslinked liquid
crystalline polymer films (xMELCP and xSSLCP) by in situ photopolymerization of LC thiol-ene monomer T6E5 and LC acrylate monomer A444 oriented by AC electric fields respectively.
The macromolecular main chains are forced to align along the normal directions
of the obtained films,
in order to enhance the ...
