However, interfacial defects between the nanofillers and PVDF matrix cause deformation and fracture of the nanofibers (NFs) during the rotation of the drum collector, hindering the effective transmission of tension to the NFs. In this study, surface modification of BaTiO₃ (BTO) nanoparticles (NPs) with polydopamine (PDA) was performed to enhance their interfacial compatibility with PVDF, ensuring effective stretching of the NFs even at high rotational speeds of the drum collector. When PDA-coated BTO (BTO@PDA) NPs were used as nanofillers in the PVDF matrix, the interfacial defects and NP agglomerations were reduced, and the interfacial interaction with PVDF was reinforced. This improvement enhanced the mechanical properties of the PVDF/BTO@PDA NFs, such as Young’s modulus and elongation at break. When PVDF/BTO@PDA NFs were used as the negative triboelectric material, the output performance of the triboelectric nanogenerator (TENG) was enhanced. Specifically, when BTO@PDA NPs were used as nanofillers, the output voltage and current continued to increase, even at higher drum collector rotational speeds than when BTO NPs were used.

While the end group influences the lower critical solution temperature (LCST) of both M-PNIPAM and N-PNIPAM, its effect is dramatically amplified in N-PNIPAM, leading to widely varying thermoresponsive behaviors ranging from no macroscopic phase transition to irreversible phase segregation. Furthermore, the end group effect results in greater hysteresis and enhanced bistability in N-PNIPAM, which was utilized to fabricate a heat-driven color display.

As an alternative to eliminating additional vulcanization processes and minimizing material usage for simplicity, our group offers a straightforward one-step method by adopting the peroxide-cross-linked principle to initiate the radical state that directly incorporates two monomers, namely, <i>N</i>-vinyl carbazole (NVC) with a rigid characteristic and 2-[[(butylamino)carbonyl]oxy]ethyl acrylate (BACO) with a soft characteristic, into the <i>cis</i>-PI main chain as the rubber matrix.

The synergistic effect between the dynamic H-bonds from BACO and π–π stacking from NVC, coupled with high polymer chain diffusion, are responsible for the high autonomous self-healing efficiency of &gt;90% even after a deadly cut.

To address this limitation, ethylene glycol methyl ether acrylate (EGMEA) was grafted onto an epoxidized natural rubber (ENR-25) matrix at varying grafting ratios, optimizing the curing time.
