Preparation and characterization of MWCNTs/FSiPUA hybrid film
CNTs/polymer hybrid films have been studied for hydrophobic surface in recent years. In this paper MWCNTs/FSiPUA hybrid films based on the excellent hydrophobicity have been prepared for the long term objective to prevent the marine fouling. MWCNTs/FSiPUA hybrid emulsion was prepared respectively by the methods of solution mixing with ultrasonic excitation and in-situ emulsion polymerization. Chemical and physical properties of the films were investigated by FTIR, contact angle meter and water absorption. The results showed that lauryl sodium sulfate(SDS) was a better dispersant than BYK-154 prepared via solution mixing with ultrasonic excitation. The performance of hybrid films approached by solution mixing with ultrasonic excitation was better than that by in-situ emulsion polymerization when same amount of MWCNTs was filled. The study indicated that the film surface properties reached best by both technologies when the content of MWCNTs was equal to 0.15wt％.
