This study examines the effects of mastication time and the addition of a plasticizer (acetyl tributyl citrate (ATBC)) on the properties of non-vulcanized polylactic acid/natural rubber (PLA/NR) blends using a factorial design, along with the impact of changing the weight ratio of the blends. The results reveal the formation of plasticized PLA (P-PLA)-based thermoplastics with enhanced ductility. ATBC functions as both a PLA plasticizer and a compatibilizer in the binary PLA/NR system.

Water-borne infections are considered as one of the major risky concerns regarding the sanitary state of water bodies dedicated to drinking water supply. Therefore, the employment of environmentally benign materials in water/wastewater treatment is an indispensable aspect to solve the water crisis problem in an eco-friendly and economic manner. This study describes the synthesis, characterization, and disinfection potency of different formulas of gelatin-based Gum Arabic composites, for the first time.

Novel Biobased Double Crystalline Poly(butylene succinate)--poly(butylene 2,5-thiophenedicarboxylate) Multiblock Copolymers with Excellent Thermal and Mechanical Properties and Enhanced Crystallization Behavior.

Novel biobased double crystalline poly(butylene succinate)--poly(butylene 2,5-thiophenedicarboxylate) (PBS--PBTh) multiblock copolyesters with excellent thermal and mechanical properties were prepared from two hydroxyl-terminated PBS-diol and PBTh-diol prepolymers via a chain extension reaction. Both PBS and PBTh segments were semicrystalline, with the aliphatic PBS segment being the soft segment while the aromatic PBTh segment was the hard segment. In the case of PBS--PBTh, the two segments were partially miscible in the amorphous region; moreover, the melting temperature of each segment still remained very high compared with that of each homopolyester PBS and PBTh.

Understanding the impact of molecular structure on the molecular packing arrangement and aggregation behaviors of organic semiconductor materials is crucial for investigating their properties in multiple organic photoelectrical applications. In this study, a high-performance polymer donor based on dithieno[2,3-:2',3'-]benzo[1,2-:4,5-']dithiophene (DTBDT) and 5,6-difluorobenzo[][1,2,5]thiadiazole (FBT) unit, named PDTBDT-Cl-TFBT, was designed and synthesized by introducing an asymmetric 3-octylthiophene π-bridge between the donor and acceptor segment. The density functional theory (DFT) calculation reveals that the asymmetric π-bridge increases the average dipole moment of the repeating units as well as the configurational disorder in polymer PDTBDT-Cl-TFBT, resulting in the overall diminished self-aggregation and crystallinity, which leads to higher miscibility with the nonfullerene acceptor Y6 than that of the symmetric π-bridge-modified polymer PDTBDT-Cl-DTFBT.
