Abstract

In order to improve the dispersive and lipophilic properties of Nano-Al2O3 in composite coatings, surface modification of Nano-Al2O3 by titanate coupling agent TC-114 was researched. The modification effect on Nano-Al2O3 was measured with the activation index and the lipophilic degree. The influences of modification dosage, time and temperature were also discussed. The results showed that Nano-Al2O3 was successfully modified with TC-114 which analyzed by FT-IR, and its hydrophobicity increased. The optimal conditions of modification were as follows: the TC-114 was 2 wt%, based on the quality of Nano-Al2O3, modification time was 50 min and temperature was 60 ?C. The activation index of modified Nano-Al2O3 was 94 % and the lipophilic degree was 35 % under the best modified conditions. The hydrophily and lipophilicity experiments indicated that modified Nano-Al2O3 possessed well lipophilicity and could dissolve in xylene.
