摘要：
Nanoscale titanium dioxide powder were prepared in terms of sol-gel process with Ti(OC4H9) as raw material. TEM analysis show that the size of nanoparticle are between 50 100nm. The results of XRD test indicate that the crystal style of the product is rutile type. In order to apply nanoscale titanium dioxide to coating as pigment, the nanoscale particles were modified in terms of esterifying reaction,silane coupling agent and organic titanate coupling agent. The results of contact angle test show that the oleophilic of modified product with organic titanate coupling agent is stronger than that with slime coupling agent and esterifying reaction.
