Preparation method of friction nano generator electrode based on polyvinyl alcohol/sodium carboxymethyl cellulose hydrogel

The invention discloses a preparation method of a friction nano-generator electrode based on polyvinyl alcohol/sodium carboxymethylcellulose hydrogel, and effectively solves the defects of poor flexibility, complex preparation method, instability of physical crosslinking and poor stretchability of the existing hydrogel friction nano-generator electrode. The friction nano-generator electrode based on the polyvinyl alcohol/sodium carboxymethylcellulose hydrogel prepared by the method is further prepared into a friction nano-generator, has the characteristics of low cost and portability, and can realize conversion from mechanical energy to electric energy in a manner of being in contact and separation with an electropositive material in the outside. 本发明公开了一种基于聚乙烯醇/羧甲基纤维素钠水凝胶的摩擦纳米发电机电极的制备方法，有效解决了目前水凝胶摩擦纳米发电机电极柔韧性差、制备方法复杂、物理交联的不稳定性及拉伸性差的缺点，该方法制备的基于聚乙烯醇/羧甲基纤维素钠水凝胶的摩擦纳米发电机电极，进一步制成摩擦纳米发电机，具有成本低廉及便携的特点，它可以通过与外界中呈电正性的材料进行接触分离方式来实现机械能向电能的转化。
