Abstract
In order to investigate the effects of film-forming morphology of fluorine-free water repellent e-mulsion on water repellent properties,the poly(octadecyl acrylate-butyl acrylate)(P(SA-BA))latex obtained by polymerization of fine emulsion was proportionally mixed with four particle sizes poly(octadecyl acry-late/γ-methylacryloxy propyl trimethoxysilane)(P(SA-A174))latices respectively.And then the glass sheets and fabrics were finished by coating and dipping processes,the surface morphologies of the two substrates were studied by SEM and AFM and the effects of water repellency were investigated.The results showed that P(SA-BA)and P(SA-A174)had the ability of film formation and shape preservation respectively.The latex compound of both could form a water repellent film with a nano-"spike"morphology,significantly enhancing the water repellent properties of the finished substrate.With the increase of the particle size of P(SA-A174)and its dosage,both the height and the surface density of the"spike"of the coating-finished film increased simultane-ously.During the dipping finishing process,only the"spike"height increased while the surface density and water repellent properties did not change significantly.Afterwards,with the decrease of pH value of dipping solution,the affinity and adsorption efficiency of latex to fabric were enhanced,and the water repellent properties of the dipping-finished fabrics were improved obviously.关键词
