摘要
用透射电子显微镜(TEM)表征由氧化锌、聚丙烯酸盐和硅酮制备三元纳米体系,发现纳米粒子为单核或多核的微囊式结构,囊芯为纳米氧化锌粒子,囊壁由聚丙烯酸盐、硅酮互穿混合而成;表面显示负电性,其微观形貌为链状或簇状的非规则球形;通过研究重力、超声波振荡时间、pH值等条件对纳米体系稳定性的影响,采用浸-轧-烘整理工艺用氧化锌三元纳米体系处理棉织物,用扫描电子显微镜(SEM)观察织物载体上纳米粒子微观形貌,提出了纳米粒子在织物载体上堆积和团聚的收缩效应模型。
The prepared ternary nano system composed of ZnO,polyacrylate, organosilicon was characterized by TEM （transmission electron microscope）. It is observed that nano particles are one or multi pit micro-purse structure. The core is nano ZnO and the wall is overlapped by polyacrylate and organosilicon. The surface of micro-purse charge is negative. The micro morphology is chain or cluster irregular sphericity. Influences of gravity, ultrasonic vibrating time and pH value on the stability of nano ZnO system were discussed. Cotton fabric was treated with ZnO ternary nano system via pad-dry process. SEM （scanning electron microscope） is used to characterize the micro-shape of nano ZnO system on the cotton fabric carrier. On this basis, the shrinking model of nano ZnO piled and aggregated on cotton fabric carrier is put forward.
