De-symmetrizing periodically grafted amphiphilic copolymers: design, synthesis and generation of Janus folded chains

Sarkar, Ramkrishna; Gowd, E. Bhoje; Ramakrishnan, S.

Periodically grafted amphiphilic copolymers (PGACs) were earlier shown to fold in a zigzag fashion to enable segregation of the two immiscible segments, namely the backbone and the pendant segments; crystallization of one or both segments led to the formation of a lamellar structure with the two segments located in alternate…

Enhanced functional properties of biopolymer film incorporated with curcurmin-loaded mesoporous silica nanoparticles for food packaging

Wu, Chunhua; Zhu, Yang; Wu, Tiantian; Wang, Lin; Yuan, Yi; Chen, Jicheng; Hu, Yaqin; Pang, Jie

Curcumin loaded mesoporous silica nanoparticle (SBA-15) was incorporated into chitosan (CS) film to improve the functional properties of pure CS film. Curcumin was loaded into SBA-15 (SBA-15-Cur) through a rotavapor method. The structural properties of SBA-15-Cur were characterised in detail by small-angle X-ray scattering, fourier transform-infrared (FT-IR) spectroscopy, transmission electron…

Sustainable in Situ Approach to Covalently Functionalize Graphene Oxide with POSS Molecules Possessing Extremely Low Dielectric Behavior

Joseph, Angel Mary; Nagendra, Baku; Surendran, K. P.; Gowd, E. Bhoje

Incorporation of multifunctional inorganic additives into the commercial polymers still stands as the most captivating and effective way to realize new-generation electronic components. Here, we introduce a simple, cost-effective, and environmentally benign method to covalently functionalize graphene oxide (GO) with vinyl- and aminopropyl-functionalized hybrid silica spheres with a polyhedral…

Real-time monitoring of interaction between ball and racket can provide the extremely important information for high quality guidance of individual table tennis training. However, the existing visual monitoring system is hard to reflect the specific interaction force and accurate hit position. Here, we design a self-powered rich lamellar crystal baklava-structured…

Influence of Trimethylsilyl Side Groups on the Molecular Mobility and Charge Transport in Highly Permeable Glassy Polynorbornenes

Yin, Huajie; Chapala, Pavel; Bermeshev, Maxim; Pauw, Brian R.; Schönhals, Andreas; Böhning, Martin

Superglassy polymers with a large fractional free volume have emerged as novel materials with a broad range of applications, especially in the field of membrane separations. Highly permeable addition-type substituted polynorbornenes with high thermal resistance and chemical stability are among the most promising materials. The major obstacle for extending the…

Insight into shear-induced modification for improving processability of polymers: Effect of shear rate on the evolution of entanglement state

Fu, Jiaxin; Wang, Yingxiong; Shen, Kaizhi; Fu, Qiang; Zhang, Jie

Many experimental results have revealed that the re-entanglement kinetics of disentangled polymers is much slower than that predicted by tube theory. This retarded recovery of fully entangled state is of practical significance that shear-induced modification may offer a way to improve processability for a polymer by reducing viscosity. This work…

The mesomorphic isotactic polypropylene was prepared by rapid compression instead of the common method of temperature quenching, and their phase transition under high pressure was investigated in depth by combining wide-angle X-ray diffraction, small-angle X-ray scattering, and differential scanning calorimetry techniques. It was found that annealing under pressure can promote…
