采用硬脂酰氯对聚苯乙烯进行改性，合成了一系列新型高分子固-固相变材料聚（苯乙烯-对硬脂酰苯乙烯）共聚物。用傅里叶变换红外光谱和偏光显微镜分别对合成共聚物的化学结构和结晶形态进行了表征。采用差示扫描量热法和热重分析法研究了SSPCMs的储能性能和热稳定性。此外，用热性能分析仪测量了SSPCM的热导率。此外，热循环测试表明，共聚物具有良好的热可靠性和化学稳定性后，经过5000个加热/冷却循环。合成的聚（苯乙烯-硬脂酰苯乙烯）共聚物作为新型SSPCM具有相当大的潜力，用于热能储存和温度控制的应用。© 2012 Wiley Periodicals，Inc.应用聚合物科学杂志，2012年
A series of poly(styrene-co-p-stearoyl styrene) copolymers as novel polymeric solid–solid phase-change materials (SSPCMs) were synthesized by the modification of polystyrene with stearoyl chloride. The chemical structure and crystalline morphology of the synthesized copolymers were determined with Fourier transform infrared spectroscopy and polarized optical microscopy, respectively. The thermal energy storage properties and thermal stability of the SSPCMs were investigated with differential scanning calorimetry and thermogravimetric analysis, respectively. In addition, the thermal conductivity of the SSPCMs was measured with a thermal property analyzer. Moreover, thermal cycling tests showed that the copolymers had good thermal reliability and chemical stability after being subjected to 5000 heating/cooling cycles. The synthesized poly(styrene-co-stearoyl styrene) copolymers as novel SSPCMs have considerable potential for thermal energy storage and temperature-control applications. © 2012 Wiley Periodicals, Inc.
