Problems solved by technology

Many studies have mixed conductive polymers (CP) into alginate gels to modify neural electrode materials through electropolymerization. The conductive polymers (CP) are only aggregated at the contact sites between the electrode recording sites and the hydrogel, and are not evenly distributed. In hydrogels, the conductivity of conductive polymers (CP) is limited

Embodiment 1

[0020] Please refer to figure 1 , figure 2 , image 3 and Figure 4 , a preparation method of nerve electrodes, such as figure 1 As shown, the microwire electrode was electro-deposited with conductive polymer (CP) to form a conductive polymer (CP) coating, and then passed through alginate gel (Al) / multi-walled carbon nanotubes (CNT) / conductive polymer (CP) ) after electrodeposition to form an alginate gel (Al) / multi-walled carbon nanotube (CNT) / conductive polymer (CP) coating, and finally undergo electropolymerization of the conductive polymer (CP) in the gel to form a conductive polymerization of point polymerization Things (CP) network.

[0021] The specific process is as follows: prepare 100 mL of 0.1wt% EDOT and 0.2wt% PSS solution, and conduct ultrasonic treatment until the EDOT monomer is uniformly dispersed to prepare a conductive polymer (CP) electroplating solution. 6mg / mL multi-walled carbon nanotubes (CNT) were dispersed in PEDOT / PSS (1.3-1.7wt%) solution by u...

Abstract

The invention discloses a nerve electrode and a preparation method thereof. The nerve electrode comprises a substrate electrode. The invention particularly relates to nerve electrodes of an alginate gel (Al), a multi-walled carbon nanotube (CNT), and a conductive polymer (CP) and a preparation method thereof. The flexibility of the alginate gel (Al) and the conductivity of the conductive polymer (CP) are both achieved, the biocompatibility is good, and the nerve electrodes are closely combined with the substrate electrode. Therefore, according to the neural electrodes of the alginate gel (Al),the multi-walled carbon nanotube (CNT) and the conductive polymer (CP), the signal sensitivity and long term safety requirements of the nerve electrodes are met.

Description

technical field [0001] The invention belongs to the technical field of new biomaterials, and relates to a nerve electrode and a preparation method thereof, in particular to a nerve electrode made of alginate gel, multi-walled carbon nanotubes, and a conductive polymer and a preparation method thereof, and the modified nerve electrode It has good electrochemical performance and excellent biocompatibility. Background technique [0002] Nerve electrodes are used to record nerve action potentials and signal input. The contact interface between the signal recording site and the nerve tissue is a key factor affecting its performance. Due to the mismatch between the recording site and the physical and chemical properties of the nerve tissue, nerve tissue is often caused. Inflammatory response and electrode failure, nerve electrodes have technical bottlenecks in terms of signal sensitivity and long-term safety. It is urgent to develop new electrode modification materials to improve ...
