纳米ZnO的表面改性研究

Surface modification of nanometer ZnO

研究了纳米ZnO表面改性的影响因素 ,确定了最优改性剂和改性条件。通过正交实验以月桂酸钠为改性剂、用量为 1 5 %、pH值为 6、改性时间为 1 .5h时 ,改性后的纳米ZnO的亲油化度达到 79.2 % 。

The surface modification of nanometer ZnO power and the effect factors are studied,the optimal modifying agent and condition are found . Using sodium laurate as modifying agent in the optimal condition ,the lipophilic degree of modified nanometer ZnO is 79.2% and the powers are well dispersed in methanol and xylene.
