    • A faster and more efficient method for applying ultra thin films to substrate surfaces is disclosed. The method comprises heating a film forming composition comprising amphiphilic molecules to a liquid state, immersing the substrate surface in the heated liquid composition to heat the surface, and washing away the excess composition. For surfaces that ordinarily have insufficient or no chemical moieties reactive with the amphiphilic molecules, the immersion in the heated composition causes the substrate to become porous and expose previously unavailable chemically reactive moieties in the surface matrix. The amphiphilic molecules then self-assemble, chemically bond to the surface matrix and self-polymerize with each other and with other surface matrix-bound and/or surface-bound molecules to form the ultra thin surface film. The method is also faster and more efficient for coating non porous and metal surfaces.
    • 公开了一种更快和更有效的将超薄膜应用于基材表面的方法。 该方法包括将包含两亲分子的成膜组合物加热至液态,将该基底表面浸入加热的液体组合物中以加热该表面,并洗去过量的组合物。 对于通常不具有足够或不具有与两亲性分子反应的化学部分的表面而言,浸入加热的组合物中导致基材变得多孔并且暴露表面基质中先前不可用的化学反应性部分。 两亲分子然后自组装,化学键合到表面基质并且彼此自身聚合并与其他表面基质结合和/或表面结合分子自聚,形成超薄表面膜。 该方法对于涂布无孔和金属表面也更快且更高效。
