    • A fibrillar, nanotextured coating is deposited on a substrate by contacting the substrate with a reaction mixture comprising a reagent which is hydrolyzable to produced a cross-linked reaction product, and a first solvent which solvates the reagent and the reaction product. The reagent is hydrolyzed so as to provide a cross-linked reaction product which is bonded to the substrate. The substrate is then contacted with a second solvent which is a non-solvent for the reaction product so as to cause nanoscopic phase separation of the reaction product, resulting in the formation of a fibrillar nanotextured coating which is bonded to the substrate. The thus produced coating may be subjected to further chemical modification. The method may be utilized to produce superhydrophobic coatings. Also disclosed are coatings made by the method of the present invention.
    • 通过使底物与包含可水解产生交联反应产物的试剂的反应混合物和溶剂化试剂和反应产物的第一溶剂接触将原纤维,纳米纹理涂层沉积在基材上。 将试剂水解以提供与基材结合的交联反应产物。 然后将底物与作为反应产物的非溶剂的第二溶剂接触,以引起反应产物的纳米相分离,导致形成结合到基材上的纤维状纳米纹理涂层。 可以对如此制得的涂层进行进一步的化学改性。 该方法可用于制备超疏水涂层。 还公开了通过本发明的方法制备的涂层。

    • A molecule for Langmuir-Blodgett (LB) deposition of a molecular layer. The molecule includes at least one switching moiety, a hydrophilicity-modifiable connecting group attached to one end of the moiety, and a hydrophilicity-non-modifiable connecting group attached to the other end of the moiety. The hydrophilicity-modifiable connecting group is transformable to a temporary end group upon adjustment in pH of the aqueous environment containing the molecule. The temporary end group is more hydrophilic than the hydrophilicity-modifiable connecting group and the hydrophilicity-non-modifiable connecting group. The difference in hydrophilicity between the temporary end group and the hydrophilicity-non-modifiable connecting group causes formation of a substantially well-oriented, uniform LB film at a water/solvent and/or water/air interface.
    • 分子用于Langmuir-Blodgett(LB)沉积分子层。 该分子包括至少一个切换部分,连接到该部分的一端的亲水性可修饰的连接基团和连接到部分的另一端的亲水性 - 不可修饰的连接基团。 当调节包含分子的水性环境的pH时,亲水性可连接基团可转变成临时端基。 临时端基比亲水性可连接基团和亲水性不可修饰的连接基团更亲水。 临时端基与亲水不连接基团之间的亲水性差异导致在水/溶剂和/或水/空气界面处形成基本良好取向的均匀LB膜。
