In this paper, nano-Ag coated eggplant-based biological porous carbon (BPC) was used as the support material to load PEG to solve the problem of leakage and low thermal conductivity of phase change material (PCM). A series of support materials (caky BPC, caky BPC@Ag, BPC powders, BPC@Ag powders) were prepared. The results show that the shape-stabilized PCM (ss-PCM) obtained by caky BPC had better anti-leakage ability. The thermal conductivity of the support material coated with nano-Ag particles was increased by 40.9 % compared with the uncoated support material. After ten thermal cycles, the composite ss-PCM (ss-CPCM) remained to exhibited excellent thermal reliability, which indicated that the ss-CPCM supported by nano-Ag coated BPC had excellent potential in practical application. In addition, BPC@Ag improved the light-to-heat conversion rate and had more application prospects. In addition, BPC had a high photo-thermal conversion efficiency, and BPC@Ag further improved the photo-thermal conversion.

本文采用纳米银包覆茄子基生物多孔碳（BPC）作为载体材料负载PEG，以解决相变材料（PCM）泄漏和导热率低的问题。制备了一系列载体材料（块状 BPC、块状 BPC@Ag、BPC 粉末、BPC@Ag 粉末）。结果表明，由caky BPC得到的形状稳定的PCM（ss-PCM）具有较好的抗渗漏能力。与未涂覆的支撑材料相比，涂覆有纳米银颗粒的支撑材料的热导率增加了 40.9%。经过 10 次热循环后，复合 ss-PCM（ss-CPCM）仍然表现出优异的热可靠性，这表明由纳米银包覆 BPC 支撑的 ss-CPCM 在实际应用中具有出色的潜力。此外，BPC@Ag提高了光热转化率，具有更多的应用前景。此外，BPC具有较高的光热转换效率，BPC@Ag进一步提高了光热转换效率。
