    In this article, the octamethylcyclotetrasiloxane is introduced into ethylene glycol. The reaction is terminated using acrylic acid to obtain a linear polydimethylsiloxane intermediate comprising double bonds at the ends. The targeted copolymer is prepared by copolymerizing polydimethylsiloxane intermediate and butyl methacrylate. Additionally, blended-porous film is prepared by adding the copolymer to the cyclodex-trin copolymer. The results reveal that the thermal stability of the copolymer increases with the increase of the polydimethylsiloxane content. The ethanol solution of the copolymer of a certain formulation has temperature sensitivity. The contact angle hysteresis of cyclodextrin copolymer is larger on the inclined surface at five degrees from the horizontal, but the blended-porous films all have low contact angle hysteresis, and the minimum contact angle hysteresis decreased to 2 degrees. The main reason for the observed difference is that the presence of the copolymer makes the surface morphology of the film changed greatly. The blended-porous films have a waterproof and easy-to-slide surface.
