Summary: This article prepared advanced biodegradable thermoplastic elastomer (BTPE)/reduced graphene oxide (rGO) nanocomposites using aliphatic diols, aliphatic dibasic acids, and graphene oxide (GO) as raw materials. The rGO is well dispersed in the BTPE matrix through its predispersion in aliphatic diols before the polycondensation of the polyester prepolymers. The addition of GO greatly enhances the tensile strength, elongation at break, biodegradability, and electrical conductivity of the BTPE/rGO nanocomposites.

Summary: The possibility of using coconut fatty acid diethanolamide as a bio-based polyol for the synthesis of polyurethane foam was explored. The polyol exhibited an auto-catalytic effect and shorter cream and gelation time compared to fossil-based polyol. Characterization of the polyol's chemical structure and rheology measurement showed its unique features. Substituting a portion of fossil-based polyol with the bio-based polyol resulted in comparable thermal conductivity and a transition in the foam's physical properties. The incorporation of the bio-based polyol also regulated the cellular structure and foam properties.

Summary: We have developed a new polyester material using biobased 1,18-octadecanedicarboxylic acid and ethylene glycol, which has a solid-state structure similar to polyethylene and comparable tensile properties to high density polyethylene (HDPE). Despite its crystallinity, high melting point and hydrophobic nature, the polyester-2,18 can be rapidly and completely hydrolytically degraded in vitro by naturally occurring enzymes. It also shows high biodegradability under industrial composting conditions and can be depolymerized by methanolysis for closed-loop recycling.

Summary: In this study, it was found that enzymatic hydrolysis of a biodegradable polyester in an aqueous environment resulted in the formation of a large number of microplastic particles. Non-enzymatic hydrolysis was also observed but did not produce particles within the experimental timeframe. The formation of microplastics was attributed to the uneven hydrolysis/erosion rate across the polymer film surface, resulting in the release of fragmented micro-sized protruding structures. Additionally, acidic monomers and oligomers were released during the enzymatic hydrolysis process, causing a decrease in pH. These findings highlight the significant risk of microplastic pollution from biodegradable plastics.
