Summary: This study systematically investigates the optical properties of poly(maleic anhydride-alt-vinyl acetate) (PMV) synthesized using different polymerization methods. It is found that solution polymerization and redissolving methods can increase the quantum yield of the polymer. The study also suggests that good solvents can reduce the rigidity of the polymer chains and promote the formation of clusters.

Summary: The creation of novel surface morphologies through thin-film patterning is important for controlling specific surface properties. This study investigates the structural changes of plasma-polymerized nanocomposite films after controlled hydrolysis, and observes the progressive growth of crystalline structures. The stability of the films is influenced by plasma conditions and monomer composition, and the crystalline structures are particularly formed on hydrophilic substrates.

Summary: This study investigated the physical properties of a biodegradable polymer nanocomposite comprising PHB matrix loaded with graphene nanoplatelets. Results showed that increasing solvent casting temperature resulted in decreased electrical resistivity, but aging at room temperature could lead to significant decrease in resistivity for certain conditions. Understanding the aging behavior of semicrystalline polymer nanocomposites like PHB is crucial for designing conductive polymer composites and active devices.

Summary: This study investigates the thermal aging behavior of a high-temperature resistance polymer, polyetherimide (PEI), at elevated temperatures in air. Changes in the ultimate tensile strength (UTS), glass transition temperature, and surface properties are observed, with an activation energy of 112 kJ mol(-1) identified for the effect of thermal aging on the mechanical strength of PEI. These findings suggest the potential use of PEI as a sensing material for the development of end-of-life sensors for fire-protective fabrics.
