Summary: In this study, hexagonal boron nitride (h-BN) was mixed with polylactic acid (PLA) to prepare PLA/h-BN composites. The morphology, mechanical and thermal characteristics of the composites were investigated. Thermal conductivity decreased and recovery strain decreased with increasing filler content. The amount of h-BN had a mixed effect on the recovery stress of the composite. These findings suggest that PLA/h-BN composites have potential for studying the influence of a heat-conducting filler on a shape memory effect in polylactic acid.

Summary: Smart dielectrics with self-adaptive capabilities can show excellent electric field-grading performance when subjected to an applied electric field above a critical value. However, conventional approaches require high doping rates, which increase interface thermal resistance, limit thermal conductivity improvement, and negatively impact mechanical properties. In this study, a new type of electric field-grading co-continuous phase composite (EP/SiCcf) composed of epoxy resin and SiC ceramic foam was prepared to achieve tunable nonlinear conductive performance, while improving thermal and mechanical properties. The results demonstrate the potential application of the novel composite in smart dielectric materials.

Summary: This study investigated the control of dielectric response by combining ceramic nanoparticles with silk fibroin, revealing an increase in dielectric constant with filler content and a decrease with filler size. Two relaxation processes, beta-relaxation and conductivity relaxation, were observed, with the activation energy of the conductivity process decreasing with increasing nanoparticle content and decreasing size. A Maxwell-Wagner-Sillar process related to the interface between the silk fibroin matrix and the BaTiO3 nanoparticles was also identified.

Summary: PVDF-HFP films incorporating different types of imidazolium ionic liquids with different magnetic anions and imidazolium cation chain lengths have been developed for humidity-sensing applications. The IL/PVDF-HFP composites exhibit a porous structure independently of the IL anion type and cation chain length. The inclusion of ILs induces polymer crystallization into the electroactive beta phase, with the most noticeable increase observed for PVDF-HFP/[Bmim][FeCl4]. The hybrid samples show a decrease in thermal stability and yield strength, with PVDF-HFP/[Bmim]2[Co(SCN)4] samples experiencing the most significant decrease. PVDF-HFP/[Bmim]2[Co-(SCN)4] and PVDF-HFP/[Bmim][FeCl4] composites display the highest magnetization. The PVDF-HFP/[Bmim]2[CoCl4] composite exhibits the highest relative humidity sensing response. The developed IL/polymer composites show potential for humidity sensing applications.
