Abstract:
      A kind of micro-capsule was prepared through in-situ polymerization using self-made fluoro-silicone polymer as core material and urea-formaldehyde resin as shell material. Long-term effective low surface energy coating was prepared by adding the micro-capsule. The water contact angle of the coating is about 120° . Under ultraviolet irradiation for 400 hours, the decline of water contact angle is not obvious and the surface energy is of no change.
