I’m Tsumugi, a researcher. This time, I investigated the conductivity of a mixed solution of chitosan and PVA.<\/p>\n<\/div><\/div>\n\n\n\n

Tsumugi<\/strong>
She is a second-year researcher in the Nanofiber Division of MECC.
Her hobbies include reading science magazines and the latest
research papers, as well as karate. Her special skill is speaking Chinese.

Objective<\/mark><\/strong>
Pure PVA is highly conductive, but it is written in the literature that adding chitosan greatly reduces the solution’s conductivity. Curious about whether the conductivity really decreases, I conducted an experiment to see if this effect could provide insights into successful spinning of other natural polymers (such as gelatin) if the conductivity indeed decreases.

Materials<\/mark><\/strong>
Chitosan: 100
PVA\u2460: Gohsenol EG-22P (Mitsubishi Chemical)
PVA\u2461: Kuraray Poval 217 (Kuraray)
<\/p>\n\n\n\n

Solution Preparation<\/mark><\/strong>
Chitosan was added to a 50wt% acetic acid aqueous solution to make a 3wt% solution, which was then heated and stirred at 80\u00b0C.<\/p>\n\n\n\n
