纳米SiO_2/氟碳杂化透明疏水耐磨涂层的制备及其性能研究

Preparation and Properties of Nano-silica/Fluorocarbon Hybrid Transparent Hydrophilic Wear-resistant Coatings

通过低温微波法制备了纳米二氧化硅(SiO_2)粒子,对其进行表面疏水化改性后,引入双键官能团处理,制备了一种高透明、耐磨性好且疏水的纳米SiO_2/氟碳杂化涂料。采用XRD、TEM、FTIR等手段对纳米SiO_2粒子进行了表征,并研究了改性纳米SiO_2的用量对杂化涂层的透明性、耐磨性、疏水性、强度、硬度以及耐沾污性的影响。结果表明:改性纳米SiO_2的含量对杂化涂层的透明性影响很小,杂化涂层具有较好的附着力、硬度、耐磨性、疏水性和耐沾污性,改性纳米SiO_2的最佳用量为5%。

Nano-silica（ SiO2） particles were prepared by low temperature microwave method. Moreover,a transparent wear-resistant hydrophobic nano-silica/fluorocarbon hybrid coating was prepared,which surface was hydrophobically modified and double-bond functional group introduced. Nano-silica particles were characterized by XRD,TEM,FTIR approaches. The effects of content of modified nano-SiO2 on the transparency,abrasion resistance,hydrophobicity,strength,hardness and stain resistance of the hybrid coatings were investigated. The results show that the addition of modified nano-SiO2 particles has little effect on the transparency of the hybrid coatings. The hybrid coatings exhibit excellent adhesive force,hardness,abrasion resistance,hydrophobicity and stain resistance. The optimal loading of the modified nano-SiO2 was found to be 5%.
