静电纺氧化铝纳米纤维研究

采用溶胶-凝胶法,以聚乙烯醇、硝酸铝、水为原料配制出了硝酸铝/聚乙烯醇溶胶-凝胶纺丝液,并通过静电纺丝技术纺制了Al(NO3)3/PVA有机-无机杂化纤维,经高温锻烧后得到了平均直径约为50～250nm无机纳米氧化铝纤维。

Preparation and Properties of Antibacterial Lyocell Fibers Containing Chitosan Derivative

IntroductionThe spinning of cellulose fibers directly from asolution, e .g .N-methyl morpholine-N-oxide , NMMO,isusually regarded as the lyocell fiber . Generally ,this lyocellprocess is environmentally friendly and the fiber isbiodegradable with good physical properties and mechanicalparameters . However , several attempts have been madeable to modify the lyocell fibers with novel properties ,e .g .by adding other polymers in the process to change itsstructure and properties[1,2].Chitosan …
