摘要：
Room Temperature Vulcanized Silicone Rubber (RTV-SR) was prepared using a composite cross-linking agent. Active groups were introduced onto silicone rubber surface by plasma, and poly(acrylamide)(PAM) was then grafted via surface-initiated atom transfer radical polymerization. The structure, composition, morphology and properties of the modified SR film were characterized by Fourier Transform Infrared Spectrometry (FT-IR/ATR), Contact Angle, XPS, and SEM before and after modification. The bacterial modified silicone rubber was studied by bacterial adhesion on the adhesion experiment. The water contact angle of the SR film decreased from 108.5° to 49.5° after grafting with PAM. The bacterial adhesion experiment data show that the surface structure and performance of SR have a great effect on bacterial adhesion. Compared with raw SR, the amount of bacterial adhesion decreased by 98.7% on the SR film grafted with PAM. © 2016, Zhejiang University. All right reserved.
