摘要：
In this paper, a water dispersible hydrophobic monomer with C==C bond based on graphene (IHGOE) was prepared by grafting hydrophobic alkyl chain derived from glycidyl neodecanoate (E10P) through chemical action with hydroxyethyl methacrylate (HEMA), and isophorone diisocyanate (IPDI). Hybrid emulsion with core/shell structure was further prepared by free radical polymerization with acrylate monomers after introducing the IHGOE into the shell layer. And its structure was chartered by FTIR, XPS, TG, SEM, and DSL. The effects of the IHGOE on the performance of practical application was also investigated including the water contact angle (CA), adhesion, hardness, water resistance, water resistance. The results demonstrated that the film of the emulsion exhibited the best performance when the mass fraction of IHGOE in the emulsion formulation was 20%, i.e. the CA of 110.8° overmatched the pure acrylate emulsion film with CA of 74.3°, which greatly enhanced its water proof. The adhesion of the film is 0 grade, the hardness is 2H, the resistant time of boiling water reached one hour, water-resistant immersion time was above 48h, butanone-resistant wiping (1kg) was above 100 times, and both the immersion time in 5% NaOH and 5% HCl solution were above 24h. © 2020, Chemical Industry Press Co., Ltd..
