摘　　要：采用铝酸酯偶联剂对纳米氧化锌进行表面改性,通过对偶联剂用量,反应温度,反应时间的平行试验确定最优改性条件。用亲油化度和吸水率表征改性效果。实验结果表明:最佳改性条件是铝酸酯用量为1%,反应温度为110℃,反应时间为30min,亲油化度可达到82.23%,而吸水率为3.24%。TEM表征,改性后粉体基本上消除团聚,达到单个粒子的分散。The surface of nano-zinc oxide is modified by aluminic acid ester coupling agent. The effect of modification is characterized by the degree of oil-affinity and the water-sorption rate. The test result shows that the optimizing modification condition is that aluminic acid ester content is 1%, reaction temperature is 110℃, reaction time is 30 min, and the degree of oil-affinity gets 82.23 % while the water-sorption rate reaches 3.24 %. The modified nano-zinc oxide charactered by TEM has got well dispersed and it basically gets single particle.
