    • Fluoropolymer particles are subjected to high energy treatment so as to change the chemical functionality of the particle surfaces and thereby change the surface characteristics of the particles. These characteristics improve the usefulness of these particles and can make them highly dispersible, even in water. The surface treated fluoropolymer particles are subject to a chemical crosslinking process, or alternatively, are subject to a high energy treatment process, and may optionally be pretreated with a macromolecular chemical species prior to the foregoing processes. The high energy treatment can be used to both surface treat the fluoropolymer particles and in some embodiments, may also cause chain scission of the fluoropolymers to thereby reduce the molecular weight of the fluoropolymer particles. The surface treated fluoropolymer particles can be used to form fluoropolymer coatings on various substrates.
    • 对含氟聚合物颗粒进行高能量处理,以改变颗粒表面的化学官能度,从而改变颗粒的表面特性。 这些特性提高了这些颗粒的有用性,并使其高度分散,甚至在水中。 表面处理的含氟聚合物颗粒经历化学交联过程,或者可以进行高能量处理过程,并且可以任选地在上述方法之前用大分子化学物质进行预处理。 高能量处理可以用于表面处理含氟聚合物颗粒,并且在一些实施方案中,还可能引起含氟聚合物的链断裂,从而降低含氟聚合物颗粒的分子量。 表面处理的含氟聚合物颗粒可用于在各种基材上形成含氟聚合物涂层。
