A novel elastic shape-stabilized phase change materials (SSPCMs) were obtained by reducing and vulcanizing a graphene oxide (GO) modified phase change latex (PCL), which is composed of ethylene propylene diene monomer (EPDM) and paraffin. GO as Pickering emulsifier assisted in fabricating EPDM/paraffin PCL. The zeta potential showed that the PCL was stable. Meanwhile, optical microscope and particle size test indicated that the average particle size was 3–5 μm. Scanning electron microscopy (SEM) showed that the SSPCMs were composed of reduced GO (RGO)-coated phase change composite microspheres (PCCMs). The intact RGO coating was beneficial to prevent the leakage of paraffin. According to the leakage rate test, the leakage rate of SSPCMs were decreased. When the GO content was 0.5%, the leakage rate of SSPCMs was 0.3%. The mechanical properties test showed that the tensile strength and elongation at break were up to 2.26 MPa and 1663.53%, respectively. The comprehensive properties of the prepared SSPCM make it have great potential in the field of building temperature control.

通过还原和硫化由乙烯丙烯二烯单体（EPDM）和石蜡组成的氧化石墨烯（GO）改性相变胶乳（PCL），获得了一种新型的弹性形状稳定相变材料（SSPCM）。GO作为Pickering乳化剂协助制造EPDM /石蜡PCL。ζ电位表明PCL是稳定的。同时，光学显微镜和粒度测试表明平均粒度为3–5μm。扫描电子显微镜（SEM）显示，SSPCMs由还原GO（RGO）涂层相变复合微球（PCCM）组成。完整的RGO涂层有利于防止石蜡泄漏。根据泄漏率测试，SSPCM的泄漏率降低了。当GO含量为0.5％时，SSPCM的泄漏率为0.3％。力学性能测试表明，其拉伸强度和断裂伸长率分别高达2.26 MPa和1663.53％。所制备的SSPCM的综合性能使其在建筑温度控制领域具有巨大的潜力。
