Problems solved by technology

[0002] The electrospinning of chitosan composite nanofibers has problems such as pure spinning difficulties. By adding polymer polymer polyvinyl alcohol and adjusting process parameters, chitosan / polyvinyl alcohol composite nanofibers were prepared, which significantly improved the chitosan composite nanofibers. Spinning performance of sugar, but polyvinyl alcohol is difficult to dissolve, which affects the spinnability and shape of the fiber

Abstract

The invention provides a nano composite fiber. The nano composite fiber is prepared by the following steps: chitosan is dissolved in an acetic acid aqueous solution to prepare a chitosan solution withthe concentration of 5.5%-5.9%; and 28-45 parts of a 11%-15% polyvinyl alcohol solution is added into 85-120 parts of the chitosan solution and blended, then uniform ultrasonic dispersion is conducted, and still standing and defoaming are conducted to obtain a spinning solution. The invention also provides a preparation method of the nano composite fiber. According to the nano composite fiber, the weight part ratio of the chitosan solution to the polyvinyl alcohol solution is given, so that the nano composite fiber with smooth morphology and strong interaction can be obtained; and by improving process parameters, the spinning performance of chitosan is improved, and the morphological characteristics of the nano composite fiber can be improved.

Description

technical field [0001] The invention relates to the technical field of nanocomposite fiber preparation, in particular to a nanocomposite fiber and a preparation method. Background technique [0002] The electrospinning of chitosan composite nanofibers has problems such as pure spinning difficulties. By adding polymer polymer polyvinyl alcohol and adjusting process parameters, chitosan / polyvinyl alcohol composite nanofibers were prepared, which significantly improved the chitosan composite nanofibers. Spinning performance of sugar, but polyvinyl alcohol is difficult to dissolve, which affects the spinnability and shape of the fiber. Contents of the invention [0003] The nanocomposite fiber provided by the invention provides the ratio of chitosan solution and polyvinyl alcohol solution in parts by weight, and can obtain the nanocomposite fiber with smooth appearance and strong interaction. [0004] The invention also provides a preparation method of the nanocomposite fiber...
