“…Comparing Figure S3c with Figure S3d, it is found that the amount of N-Q increased significantly, indicating that B doping could induce the increase in N-Q content, the redistribution of electrons on the surface of carbon materials and improvement in the electrochemical performance [5,46,48]. The B 1s peak was divided into two peaks at 190.0 and 192.6 eV, corresponding to BC2O and BCO2, respectively (Figure 5d) [32,[49][50][51]. According to the comparison with the spectra of NCM, PNCM and BNPCM in Figure S3a, boron mainly came from boric acid.…”

The optimization of supercapacitive properties in carbon materials derived from cheap and sustainable wood scraps exhibits great application potential. Herein, in support of interfacial groups, polyaniline nanospheres were in situ constructed in the internal pore structure of wood scraps; further, the B and N elements were imported by carbonized and hydrothermal methods. The doped B regulated the species of N doping to improve the electrical conductivity of carbonized wood scraps, and it endowed a certain pseudo-capacitance. Coupled with the fine double-layer capacitance from the hierarchical structures constructed by carbonized nanospheres and wood scrap channels, a high specific capacitance of 406 F g−1 at 0.5 A g−1, high energy density (17.71 Wh kg−1 at 250 W kg−1) and cycle stability (93.04% capacitance retention after 10,000 cycles) were performed simultaneously. This study provided a new strategy to improve the supercapacitive performance of bio-carbon materials in terms of structure and conductance.

“…The insignificant decline might be that the PANI nanowire arrays with an ordered structure on the outer layer of the BN@PANI composite provide an effective conductive path, allowing for rapid electron transfer. 45,46 Then, the increase in the volume resistivity of the composite is due to not only the limitation of electron movement upon increasing the fraction of the BN filler with a high dielectric constant but also the disruption of the ordered structure of PANI nanowire arrays.…”

The rapid development of flexible conductive materials has promoted the research on conductive polymer (CP)‐based materials. However, CPs have relatively low thermal conductivity (TC), which can result in severe heat dissipation problems for device applications. In this work, core–sheath structured polyaniline@boron nitride (BN@PANI) composites were prepared by in‐situ growth strategy, in which PANI nanowire arrays were uniformly anchored to the surface of BN microrods. Thanks to the particular structure, the as‐prepared BN@PANI composite shows excellent thermal management capabilities. Specifically, the TC of the BN@PANI composite is 4.32 W/m·K at low BN loading of 10 wt%, which is almost 17.8 times that of pure PANI. Moreover, the excellent heat dissipation performance is intuitively presented through infrared imaging technology. Impressively, the PANI nanowire arrays are vertically arranged on the BN surface to form a conductive pathway, which results in conductivity comparable to pure PANI. This work broadens the ideas for preparing high‐performance CP‐based composites by using insulating fillers.Highlights Core–sheath structured BN@PANI composites were prepared by an in‐situ growth strategy. The thermal conductivity of composite was 4.32 W/m·K at 10 wt% BN loading. The introduction of BN had little effect on the conductivity of PANI. The BN@PANI composites possessed excellent thermal management capability. This work contributes to understanding heat transport in conductive polymers.
