I’m here to introduce a piece of literature. TsumugiShe is a second-year researcher in the Nanofiber Division of MECC. Her hobbies include reading science magazines and the latestresearch papers, as well as karate. Her special skill is speaking Chinese. Objective Notes Experimental Procedure Preparation of Polymer Solutions for Electrospinning: From these polymer solutions, four mixed solutions were prepared: Electrospinning conditions were set at a voltage of 20kV, nozzle-to-collector distance of 120mm, feed rate of 0.02ml/h, and an inner needle diameter of 806.046μm. The produced nanofiber membranes were analyzed and evaluated using various methods. Summary By using electrospinning technology with a mixture of chitosan, PVA, pectin, and CMC, nanofiber membranes were successfully created. The addition of adjuvant agents improved desirable properties for membranes intended to absorb exudate from the skin surface, such as swelling, vapor transmission, and biodegradability. The addition of adjuvant agents made the nanofibers tougher, stronger, and more flexible. The nanofiber membranes demonstrated effective contact inhibition against Staphylococcus aureus. These nanofiber membranes are excellent materials for treating skin diseases. Reflections The conductivity of PVA is high, but it seems that adding chitosan reduces the conductivity! I would like to actually experiment with this! 　　　　 Referenceshttps://www.sciencedirect.com/science/article/pii/S2211715624000109
