摘要 以纳米二氧化钛(TiO2)粒子改性的三聚氰胺-尿素-甲醛树脂为壁材,以正十四醇为芯材,采用原位聚合法制备了纳米TiO2改性的相变微胶囊。研究了乳化剂浓度以及纳米TiO2的添加量对微胶囊性能的影响,采用红外光谱、扫描电子显微镜、激光粒度分布仪、差示扫描量热仪、热重分析仪分别对微胶囊的化学结构、表面形貌、粒径分布及热性能进行了表征。结果表明,所制微胶囊的体积粒径58.2~83.6μm,受乳化剂浓度影响较大,当壁材中加入适量的纳米TiO2的添加量小于5%(wt,质量分数)条件下,微胶囊呈球形且表面光滑,随着TiO2添加量的增加,改性微胶囊的相变潜热、芯含量及热稳定性均呈先增加后降低态势,在TiO2添加量为3%(wt,质量分数)条件下,纳米TiO2改性相变微胶囊的熔融潜热达最大值151.5J/g,微胶囊芯含量为69.9%,微胶囊的热稳定性也明显提高。

Abstract: The phase change microcapsules containing tetradecanol were prepared by in-situ polymerization with melamine-urea-formaldehyde resin modified with nano titanium dioxide (nano-TiO2) as the wall materials.Various methods were used to characterize the as-prepared microcapsules so as to investigate the effect of the amount of nano-TiO2 and emulsifier concentration on performance of microcapsules,including infrared spectroscopy,laser particle size analyzer,scanning electron microscopy,differential scanning calorimetry and thermogravimetric analysis.The results indicated that the mean diameter of capsules fell in the range of 58.2~83.6μm,which was influenced greatly by the concentration of emulsifier.The microcapsules modified by less than 5wt% nano-TiO2 presented smooth and spherical morphology.The latent heat,core content and thermal stability of modified microcapsules were firstly increased and then decreased with the addition of nano-TiO2 increasing.When the mass fraction of nano-TiO2 was 3wt%,the melting latent heat was up to 151.5J/g and the core content was 69.9%.The thermostability was evidently increased.
