Flexible, high thermal conductivity, large heat enthalpy and multiresponsive of shape-stabilized phase change composites (SSPCCs) have received increasing attention in the relevant thermal energy management and storage applications. Herein, we developed a novel SSPCC with light/electric-to-thermal energy conversion and storage property, which was fabricated by encapsulating polyethylene glycol (PEG) into multi-walled carbon nanotubes (MWCNTs) and polypyrrole (PPy) decorated melamine foam (MF). The structural morphology, and shape-stabilization, thermal stability, thermal energy storage, thermal reliability, thermal conductivity, temperature regulation, photo/electro to thermal conversion properties of fabricated SSPCCs were explored. The results revealed that MF sponge framework decorated with MWCNTs by dip-coating and PPy by in-situ polymerization, showed highly porous structure and great absorption capacity (up to 97.9 wt%) for PEG. After impregnating PEG, the fabricated SSPCCs exhibited high latent thermal storage capacity of 165.1 J/g, excellent shape-stabilization and thermal reliability, improved thermal conductivity with 160.8 % higher than that of pure PEG, and great temperature regulation ability. Due to dual responses to light and electricity, the SSPCCs demonstrated a prominent photo/electro to thermal conversion capability. It provides an innovative route toward the design and development of multifunctional phase change composites for great potential in solar energy utilization, constructing energy conservation buildings, heat preservation, and infrared thermal stealth.

形状稳定相变复合材料 (SSPCC) 的柔性、高导热性、大热焓和多响应性在相关热能管理和存储应用中受到越来越多的关注。在此，我们开发了一种具有光/电-热能转换和存储特性的新型 SSPCC，它是通过将聚乙二醇 (PEG) 封装到多壁碳纳米管 (MWCNT) 和聚吡咯 (PPy) 装饰的三聚氰胺泡沫 (MF) 中制成的。 ）。研究了制造的 SSPCC 的结构形态、形状稳定性、热稳定性、热能储存、热可靠性、热导率、温度调节、光电/热转换性能。结果表明，通过浸涂和 PPy 通过浸涂和 PPy 装饰的 MF 海绵框架对 PEG 显示出高度多孔的结构和巨大的吸收能力（高达 97.9 wt%）。浸渍 PEG 后，制备的 SSPCCs 表现出 165.1 J/g 的高潜热储存容量、优异的形状稳定性和热可靠性、热导率比纯 PEG 高 160.8%，以及良好的温度调节能力。由于对光和电的双重响应，SSPCC 表现出突出的光/电热转换能力。它为多功能相变复合材料的设计和开发提供了一条创新途径，在太阳能利用、建造节能建筑、保温、
