Abstract: |
The PHEMA membrane was obtained by the UV-induced polymerization of hydroxyethyl methacrylate (HEMA) on the porous cotton woven fabric surface,which was pre-modifiled by the Maleic anhydride (MAH),and also it focused on exploring the influence of the concentration of hydroxy ethyl methacrylate to the polymer film morphology,and its effected on the fabric pore structure and surface hydrophilicity.The researches have shown that the grafting degree of maleic anhydride could reach 8.87% when the reaction temperature and time were 90C and 4h, the monomer concentration was 1.5mol/L;the Infrared spectrum analysised that it appeared obvious carbonyl peak and carbon double bond in 1728cm-1 and 1641cm-1.Meanwhile,the PHEMA membrane morphology structure and hydrophilicity on the surface of the fabric were characterized by the SEM and CA,and the result was that the porosity of the between fibers were effectively covered by the polymer film,the CA of the cotton surface could reach 130,but warter-drop seeped into the cotton fabric about afer16 seconds. |
