【摘要】：采用戊二醛交聯(lián)殼聚糖溶液浸軋?zhí)幚斫?jīng)氧氣等離子體處理后的靜電紡聚砜超細(xì)纖維膜,研究戊二醛體積百分比對(duì)處理后纖維膜的孔隙結(jié)構(gòu)、親水性、力學(xué)性能和純水通量的影響。結(jié)果表明:經(jīng)戊二醛交聯(lián)殼聚糖溶液浸軋?zhí)幚砗?纖維膜的孔徑明顯變小,親水性和拉伸力學(xué)性能得到顯著改善。最佳戊二醛體積百分比為0.40%,此時(shí)處理后纖維膜仍具有發(fā)達(dá)的孔隙結(jié)構(gòu),平均孔徑為2.62μm,力學(xué)性能顯著增強(qiáng),纖維膜由疏水轉(zhuǎn)變?yōu)橛H水,且純水通量為(1 624.7±189.5)L/(m~2·h)。
[Abstract]:The ultrafine fiber membrane of electrospun polysulfone treated by oxygen plasma was treated with glutaraldehyde crosslinked chitosan solution. The effect of volume percentage of glutaraldehyde on pore structure and hydrophilicity of treated membrane was studied. Effects of mechanical properties and pure water flux. The results showed that the pore size of the fiber membrane was obviously reduced and the hydrophilicity and tensile mechanical properties were improved obviously after the treatment of glutaraldehyde crosslinked chitosan solution. The optimum volume percentage of glutaraldehyde was 0.400.The fiber membrane still had developed pore structure after treatment, the average pore size was 2.62 渭 m, the mechanical properties were significantly enhanced, the fiber membrane changed from hydrophobic to hydrophilic, and the pure water flux was (1 624.7 鹵189.5) L / (m ~ (2) h).
