Preparation method of oriented conductive hydrogel fiber material

Abstract

The invention discloses an oriented conductive hydrogel fiber material and a preparation method thereof. The preparation method comprises the steps: firstly, conductive particle dispersion solutions with different concentrations are obtained through an ultrasonic dispersion method, and dispersed conductive particles are turned into an evenly dispersed state from a mutually agglomerated or wound state so as to meet the subsequent requirements of enhancing the matrix strength and conductivity; then the conductive particles are composited into an organic polymer solution capable of being gelifiedto form a composite electrospinning precursor solution meeting the electrospinning concentration and viscosity; and electrospinning is conducted through a liquid rotary receiving disc, and a polymercomposite conductive particle hydrogel fiber with an oriented micro-nanofiber structure is prepared. Different from the traditional design of hydrogel single physical factor introduction, the orientedmicro-nanofiber structure, sensitive variable conductivity and mechanical strength are simultaneously introduced into a hydrogel system, the hydrogel fiber material with excellent performance is prepared, and a new preparation technique is provided for material preparation of the fields such as biomedical stent materials, flexible electrode materials and biosensors.

Description

technical field [0001] The invention belongs to the field of materials, and particularly provides a method for preparing oriented conductive hydrogel fiber materials. Background technique [0002] Hydrogel materials have the characteristics of excellent biocompatibility, degradability, bendability and flexibility, and are widely used in the fields of biomedical scaffold materials, flexible electrodes or biosensors. In terms of the design of biomedical scaffold materials, it is often inclined to design and prepare scaffold materials with structural characteristics similar to human tissue. Such a scaffold material can well match with human tissue in terms of mechanical properties and meet the requirements of implantation. At the same time, the design and preparation of scaffold materials also take into account the functional characteristics of corresponding tissues to the greatest extent, such as the electrical conductivity of nerve tissue and muscle tissue. Therefore, the d...
