Multifunctional PLA films were fabricated through the solution casting method by incorporating cardanol oil (CA) and amine-functionalized graphene (AFG). The effect of the CA, and AFG on the structural, mechanical, thermal, thermo-mechanical and antioxidant properties of PLA films were investigated. FTIR analysis of PLA-CA films showed distinct peak positions at 1590 cm corresponding to the aromatic CC bonds of CA, showing that CA is compatible with the PLA.

User adherence contributes to the effectiveness of topical pre-exposure prophylactic products designed to protect against human immunodeficiency virus type 1 (HIV-1) infection. Long-acting approaches that do not require daily or coitally-dependent use could potentially improve user adherence. This study aims to develop a long-acting vaginal film to deliver an integrase inhibitor, MK-2048, for prevention of HIV-1 infection.

Although traditional petroleum-based packaging materials pose environmental problems, biodegradable packaging materials have attracted extensive attention from research and industry for their environmentally friendly properties. Bio-based films, as an alternative to petroleum-based packaging films, demonstrate their significant advantages in terms of environmental friendliness and resource sustainability. This paper provides an insight into the development of biomass food packaging films such as cellulose, starch, chitosan, and gelatine, including their properties, methods of preparation (e.

This study aimed to investigate the impact of adding aroeira leaf extract (Schinus terebinthifolius Raddi) to a yam starch film matrix, focusing on the development of potentially active films and the evaluation of their physicochemical, mechanical, optical, and antioxidant properties. Films were produced using the casting method with varying extract concentrations (0, 3, 6, 12, and 15 %), yam starch (2 %), and glycerol (1 %). The antioxidant properties were analyzed by determining the total phenolic content, 2,2-Diphenyl-1-Picrylhydrazyl (DPPH) radical scavenging, ferric reducing power, and 2,2-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical elimination, which revealed a significant increase in antioxidant properties as the extract concentration increased.

Poly (lactic acid) (PLA) is a widely produced bio-based polymer known for its biodegradability and renewability, but its brittleness, low heat resistance, and weak mechanical properties limit its broader use. To address these challenges, TEMPO-oxidized cellulose nanofibers (TOCNF) were extracted from dissolving pulp using TEMPO oxidation and high-pressure homogenization. These TOCNF were modified with silane to reduce hydrophilicity and improve compatibility with PLA.
