Summary: By regulating the calcination temperature, different morphologies of urchin-shaped bimetallic nickel-cobalt oxide/carbon (NiCo2O4/C) composites are prepared and their absorption properties are studied. The results show that the composites exhibit excellent absorption performance, mainly due to the interweaving needle-like structures that increase the opportunities for scattering and multiple reflections, the carbon component that enhances interfacial polarization and reduces the density of the absorber, and the generous oxygen vacancy defects that induce defect polarization and dipole polarization.

Summary: We have developed a lyophilization-free method to fabricate conductive polymer (PEDOT:PSS) foams with adjustable density and mechanical properties. By employing asymmetric acid treatment, we created a PEDOT:PSS scaffold with asymmetric light absorptivity, which exhibited asymmetric photo-thermo-electrical conversion under simple global illumination. The different doping states achieved through asymmetric acid treatment were found to be responsible for the distinct light absorptivity along the scaffold. Noninvasive photo-thermo-electrical stimulation induced significant expressions of genes related to neural differentiation in just 30 minutes under an illumination intensity of 240 mW/cm2. This research not only provides a new approach to fabricate conductive polymer foams but also demonstrates the potential for using global illumination to provoke the photo-thermo-electrical effect of conductive polymers with asymmetric light absorptivity for therapeutic purposes in tissue engineering.

Summary: For the first time, styrene-butadiene-glycidyl methacrylate (SBG) was incorporated into the recovered acrylonitrile-butadiene-styrene (rABS) and recycled high impact polystyrene (rHIPS) system by melt blending to increase effectiveness. The epoxy groups in SBG react with the butadiene aging groups in rABS/rHIPS, resulting in the formation of ester groups, which repairs broken molecular chains, improves phase compatibility, and enhances mechanical properties of the blends. Adding SBG significantly improves the molecular weight, impact strength, tensile strength, flexural strength, storage modulus, loss modulus, and complex viscosity of the blends. When SBG content is 8 wt%, the notch impact strength of the blends increases by 108% compared to rABS/rHIPS. Furthermore, the interface between the polybutadiene (PB) phase and styrene-acrylonitrile copolymer (SAN) phase becomes less distinct, improving the compatibility and enabling high-value recovery of rABS/rHIPS.

Summary: By using the PBO fiber/FABPBO-BADCy wave-transparent laminated composites prepared through high temperature molding, the mechanical properties, wave-transparent performances, and heat resistances of PBO fiber/BADCy composites are simultaneously improved. Compared to PBO fiber/BADCy composites, the interlaminar shear strength and flexural strength of PBO fiber/FABPBO-BADCy composites are increased by 33.2% and 13.3%, respectively. Furthermore, the dielectric constant and dielectric loss values are lower, and the wave transmission efficiency is higher, exhibiting excellent stability over a wide temperature and frequency range. Additionally, the heat resistance index and glass transition temperature are also improved.

Summary: In this study, paper-like flexible composite phase change materials (PCMs) were developed by hydraulic compression of polyimide foam with PCM film between an aluminum foil and a ceramic composite Parafilm (R). The thermal performance was optimized by adding nano-BN and micro-SiC particles into the Parafilm (R). The results showed that monoliths containing 30 wt% micro-SiC exhibited the best thermal performance, followed by the 60 wt% nano-BN composite. The compression process led to the irreversible collapse of the foam's cellular structure, but the high-k fillers improved impregnation and ensured excellent shape stability and leakage prevention.
