    • Methods are provided for uniform deposition of particles on curved surfaces such as fibers and coatings formed by the particles. Particles in the size range of 10-2000 nm are deposited onto a fibrous material via electrostatic interaction between charge modified fiber material surfaces and oppositely charged particles or metal ions. Various nonmetallic, bimetallic or other charged particles are deposited onto a fibrous material via electrostatic interaction between charged modified fibrous material surfaces and oppositely charged particles. Particles can be directly assembled onto a surface of a fibrous material by controlling hydrogen bonding interactions between interfaces of fibers and functionalized particles. Metal particles can also be deposited by in situ synthesis. A method is also provided for layer-by-layer deposition of particles over a fibrous material.
    • 提供了用于在诸如由颗粒形成的纤维和涂层的曲面上均匀沉积颗粒的方法。 尺寸范围为10-2000nm的颗粒通过电荷改性纤维材料表面和带相反电荷的颗粒或金属离子之间的静电相互作用沉积到纤维材料上。 各种非金属,双金属或其他带电粒子通过带电的改性纤维材料表面和带相反电荷的颗粒之间的静电相互作用沉积到纤维材料上。 通过控制纤维和功能化颗粒的界面之间的氢键相互作用,可以将颗粒直接组装到纤维材料的表面上。 金属颗粒也可以通过原位合成沉积。 还提供了一种在纤维材料上逐层沉积颗粒的方法。
