Summary: In this study, the drying rate and performance of waterborne acrylic paint film on bamboo laminated lumber for furniture were investigated under different environmental conditions. The results showed that the drying rate of the paint film was influenced by temperature, humidity, and wind speed, while the adhesion and hardness of the film were unaffected by these conditions. Based on response surface optimization, the fastest drying rate and optimal wear resistance were achieved at specific temperature, humidity, and wind speed conditions.

Summary: Amorphous gallium oxide thin films were grown using plasma-enhanced atomic layer deposition. The films exhibited decreasing band gap energy and increased density as the temperature increased. The higher substrate temperature also resulted in increased surface roughness. Films grown at temperatures below 200 degrees C were amorphous, while the film grown at 250 degrees C showed slight crystallinity.

Summary: To improve the properties of potato starch film, cinnamon essential oil (CEO) encapsulated with mesoporous nano-silica (SBA-15) was added to the film and the potato starch dispersion was modified by low-temperature plasma (LTP). The addition of SBA-15-CEO significantly improved the physical, mechanical, antioxidant, and antifungal properties of the film. The results showed reduced water vapor transmission rate (WVTR) and oxygen transmittance rate (OTR), increased tensile strength (TS) and elongation at break (EB), and exhibited antifungal and antioxidant activity.

Summary: This study investigated the toughening mechanism of iPP/EPR/SiO2 composites at low temperatures. It was found that the synergistic regulation of T-bd by EPR and SiO2, as well as the increase in silica content, could effectively enhance the low-temperature toughness of the composites. Additionally, the proposed toughening mechanism involved the increased internal friction loss induced by the expanded phase interfacial area between EPR and iPP matrix, leading to high-elastic deformation and ductile fracture behavior in the composite at low temperatures.

Summary: During plasma treatment of polymers, the etching rate can be controlled by varying the base pressure. In this study, polytetrafluoroethylene (PTFE) was subjected to plasma treatments using only He gas at various base pressures. The results showed that controlling the base pressure enables flexible selection of the ratio of functional groups generated on PTFE.

Summary: In order to enhance the surface bonding strength of polypropylene (PP) decorative films on wood panels, sodium lignosulfonate (SL) was modified with diethanolamine (DEA) to graft two long hydrocarbon chains with end hydroxyl groups onto the molecule. The resulting product reacted with waterborne polyurethane (WPU) monomers to form reinforced emulsions. This novel emulsion was used as adhesives on the back of PP decorative films and compared to unmodified SL, resulting in improved thermal properties and surface bonding strength due to its heat resistance and high stiffness.

Summary: A low-temperature process is demonstrated to transform insulating In2O3 thin-films into n-type semiconductors, enabling the development of high-performance In2O3 thin-film transistors. The H-plasma assisted annealing process, compared to thermal annealing, not only reduces processing time but also maintains the insulating nature of the untreated area.
