摘要

以熔点在58～60℃的半精炼石蜡作为相变芯材，与单体、分散剂水溶液形成核壳结构分散液，室温下自由基聚合制备甲基丙烯酸甲酯-丙烯酸的共聚物（P(MMA-co-AA)）为壳材的微胶囊.分别用相差显微镜、扫描电镜、差示扫描量热分析仪和傅里叶变换红外光谱仪测定了微胶囊的形貌、热性能和壳材化学结构.微胶囊的直径范围为1～5 μm，其中相变芯材的含量可达70%左右，具有较高的相变潜热（99 J/g），有望应用于空调、供暖等领域.

Abstract

The microcapsules containing wax encapsulated by poly(methyl methacrylate-co-acrylic acid) (P(MMA-co-AA)) with diameter in the range of 1～5 μm were fabricated by radical polymerization around the wax in a dispersion system.The chemical structure

morphology and thermal behavior of the microcapsules were studied by FTIR

phase-contrast optical microscope

SEM and thermal analysis.The thermal properties of the microcapsules revealed that the content of the core material was up to about 70%

and the microcapsules had a high latent heat (ca. 99 J/g).The dispersed microcapsules can be used as a latent functional thermal fluid to improve the heat transfer efficiency in the fields of refrigeration and air-conditioning.
