一种电流变液及其制备方法
摘要：
本发明涉及一种TiO2/H2Ti2O5纳米管电流变液材料及其制备方法，该电流变液的分散相是TiO2/H2Ti2O5纳米管复合材料，采用两步法制备而成，先采用水热法制备H2Ti2O5纳米管，然后再采用水热法或水解法在H2Ti2O5纳米管上包覆一层TiO2膜，形成一种同时具有核壳结构与异质结结构的TiO2/H2Ti2O5纳米管复合材料；该材料与甲基硅油所配成的电流变液具有一些优异的特性，包括极强的电流变效应、很好的抗沉淀稳定性、电流密度低、化学稳定性好。附图中显示了TiO2/H2Ti2O5纳米管复合材料电流变液在不同电场强度下其剪切应力与剪切速率的关系。
摘要（英）：

The invention relates to a TiO2/H2Ti2O5 nanotube electrorheological fluid material, and a preparation method thereof. According to the preparation method, a TiO2/H2Ti2O5 nanotube composite material is taken as a dispersion phase; two-step method is adopted for preparation; H2Ti2O5 nanotube is prepared via hydrothermal method firstly; the H2Ti2O5 nanotube is coated with a layer of TiO2 film via hydrothermal method or hydrolysis method so as to obtain the TiO2/H2Ti2O5 nanotube composite material of a core-shell structure and a heterojunction structure. The electrorheological fluid prepared from the TiO2/H2Ti2O5 nanotube composite material and methylsilicone oil possesses following advantages: electrorheological effect is extremely high; anti-sludging stability is high; current density is low; and chemical stability is high. The relationship of the shear stress with the shearing rate of the TiO2/H2Ti2O5 nanotube composite material electrorheological fluid at different electric field intensities is disclosed in the invention.
