The influences of PVA molecular weight, poly(DMAEMA)content and various crosslinking ratio were discussed. From the FTIR spectra, the peak of C=O increased with the increasing poly(DMAEMA)content. In the results of DSC, it was found there was one Tg, so the compatibility between PVA and poly(DMAEMA)was good. It was also found Tm decreased with the increaseing poly(DMAEMA)content cause poly(DMAEMA)could decrease the crystallinization of PVA, as the results of XRD. From the results of elemental analysis, the oxygen content in the PVA membranes decreased after treated with glutaraldehyde. It was also found that tensile strength, elongation and thermal stability increased. The effects of poly(DMAEMA)content and crosslinking ratio on the contact angle, water content and permeability of solute were determined. It was found that with an increase in the poly(DMAEMA)content, the contact angle decreased whereas the water content increased, and the higher permeability of solute. It was also found that with an decrease crosslinking ratio, the water content increased, and the higher permeability of solute. Jen-Ming Yang 楊禎明 2005 學位論文 ; thesis 95 zh-TW |
