Problems solved by technology

A porous material is very effective for one or several drugs, but may be poor for other drugs
Improving the effect of drug loading by means of physical adsorption and electrochemical adsorption has attracted people's attention. However, the effect of physical adsorption is limited, and the effect of electrochemical adsorption depends on the properties of the material itself.

Abstract

The invention provides a pyrrole and 3,4-ethylenedioxythiophene copolymerization nanowire array, also discloses a preparation method thereof, and relates to a plurality of technical fields of macromolecule copolymerization, a nanowire array, a conductive polymer material, and a macromolecule capacitor and the like. The highest current density, the discharging time, the specific capacity and the capacity retention rate of the PPE nanowire array prepared by the method are obviously higher than the current density of pyrrole and 3,4-ethylenedioxythiophene homopolymer; and poly 3,4-ethylenedioxythiophene and polypyrrole are different a lot, the electrical property of the poly 3,4-ethylenedioxythiophene is much weaker than that of the polypyrrole, meanwhile, the size of the poly 3,4-ethylenedioxythiophene is relatively large, and two annular radical groups will be perpendicular to the nanowire array and are distributed around the nanowire array during polymerization.

Description

technical field [0001] The invention provides a pyrrole and 3,4-ethylenedioxythiophene copolymerized nanowire array. The invention also discloses its preparation method, which involves multiple technologies such as polymer copolymerization, nano-array, conductive polymer material, and polymer capacitor. field. Background technique [0002] The most common problem in the process of dental implant restoration is insufficient bone mass. How to maintain bone mass and promote bone repair is an important issue. Since soft tissue grows much faster than bone tissue, soft tissue growth can interfere with bone tissue growth. Finding an ultra-thin barrier membrane to separate soft and hard tissues, on the one hand to block the growth of soft tissues, and on the other hand to maintain the space for bone tissue growth, is of great significance for preserving bone mass. [0003] Furthermore, if the barrier membrane has the functions of functional modification and drug loading, it can pr...
