摘　　要：以正十八烷为相变材料,纳米碳化锆为光热转换材料,通过改变碳化锆用量,采用原位聚合法制备了一系列基于密胺树脂/碳化锆壁材的光热转换相变功能复合微胶囊,并进行了性能测试。结果表明,合成的功能复合微胶囊具有较好的热稳定性;复合微胶囊的有效芯材含量随纳米碳化锆用量增加而降低,当碳化锆用量为1%或3%时,对微胶囊有效芯材含量影响较小;引入纳米碳化锆可以优化功能复合相变微胶囊的壁材结构,改善其过冷结晶现象;在近红外灯下,功能复合微胶囊均展现出较好的光热转换性能。N-octadecane was used as phase change material and nano zirconium carbide was used as photothermal conversion material,by changing the amount of zirconium carbide,a series of photothermal conversion-phase change functional composite microcapsules based on melamine resin/zirconium carbide were prepared by in-situ polymerization,and the performance tests were carried out.The results showed that the synthesized functional composite microcapsules had the good thermal stability.The effective core material content of composite microcapsules decreased with the increase of nanozirconium carbide dosage.When the amount of zirconium carbide was 1%or 3%,the influence of the effective core material content of microcapsules was Small.The introduction of nano zirconium carbide could optimize the wall material structure of functional composite phase change microcapsules and improve the undercooling crystallization phenomenon.Under the near infrared lamp,functional composite microcapsules showed good photothermal conversion performance.
