Crystallization-driven microstructure changes during microphase separation for environment-friendly thermoplastic triblock copolymer elastomers

Ding, Shuangshuang; Fang, Chu; Wang, Xuehui; Wang, Zhigang

A study on the crystallization-driven microstructure changes during microphase separation for a series of high transparent semicrystalline thermoplastic triblock copolymer elastomers (TBCPEs), polylactide-b-polyisoprene-b-polylactide (PLA-b-PI-b-PLA) was conducted in this work. A series of PLA-b-PI-b-PLA TBCPEs with different molecular masses of PI midblock and same molecular mass of PLA end…

Effects of charge contrast and composition on microgel formation and interactions with bacteria-mimicking liposomes

Borro, Bruno C.; Toussaint, Marie S.; Bucciarelli, Saskia; Malmsten, Martin

Microgels offer opportunities for improved delivery of antimicrobial peptides (AMP). To contribute to a foundation for rational design of such systems, we here study the effects of electrostatics on the generation of peptide-carrying microgels. For this, alginate microgels loaded with polymyxin B and cross-linked by Ca2+, were formed by electrostatic…

Regulating the phase separation of ternary organic solar cells via 3D architectured AIE molecules

Adil, Muhammad Abdullah; Zhang, Jianqi; Wang, Yuheng; Yu, Jinde; Yang, Chen; Lu, Guanghao; Wei, Zhixiang

An optimized bulk heterojunction (BHJ) interface, certifying enhanced exciton-splitting, charge separation and recombination inhibition, is vastly desired to obtain high power conversion efficiencies (PCEs). Herein, the ternary strategy has been employed to effectively modify the phase separation between the J71:ITIC blend by incorporating a 3D aggregation-induced emission (AIE) material,…

Highly Stretchable Photonic Crystal Hydrogels for a Sensitive Mechanochromic Sensor and Direct Ink Writing

Chen, Jiayao; Xu, Lirong; Yang, Meijia; Chen, Xiaochuan; Chen, Xudong; Hong, Wei

Photonic crystals, which are materials with periodic dielectric constants on the submicroscale, have been the focus of research for an extended period. Photonic soft materials have been extensively developed for use as colorimetric indicators and mechanochromic sensors, but their limited mechanical properties and molding characteristics only suitable for films restrict…

Crystallization of forms I? and form II of polybutene-1 in stretched polypropylene/polybutene-1 blends

Xu, Yao; Ma, Yaping; Liu, Chenguang; Men, Yongfeng; He, Aihua

In this work, the effects of orientated crystal morphology of polypropylene (PP) induced by tensile stretching on the subsequent crystallization behavior of polybutene-1 (PB-1) in the incompatible PP/PB-1 (50/50) blends were studied. When the PP/PB-1 blends were stretched at a temperature above melting temperature (Tm) of PB-1 but below the…
