Preparation method and application of transparent titanium dioxide nanotube film

Abstract

The invention discloses a preparation method and application of a transparent titanium dioxide nanotube film. Firstly, a titanium sheet is subjected to a primary anodic oxidation, ultrasonic cleaning and secondary anodic oxidation to form a titanium dioxide nanotube array; the titanium dioxide nanotube array is subjected to low temperature annealing; the titanium dioxide nanotube array is quickly peeled from a substrate titanium through high-voltage anodization to obtain the titanium dioxide nanotube self-supporting film with a regular shape and two transparent ends. The preparation method is simple, low in price, environment-friendly and beneficial for large-scale application. The low temperature annealing treatment can effectively protect the strength and the thickness of the film and has very important effect on the film application. The preparation method and the application of the transparent titanium dioxide nanotube film utilize intelligent response functions of ion channels in titanium dioxide nanotube film simulated organisms to built artificial ion channels with photoresponse, and overcome the instability of organic materials in the traditional artificial ion channels and the limitation of biological material application.

Description

technical field

[0001] The invention belongs to the field of nanotechnology, and relates to the preparation of a titanium dioxide nanotube array, in particular to the preparation of a self-supporting film with two ends of the titanium dioxide nanotube and its application in an artificial ion channel. Background technique

[0002] Ion channels in organisms can intelligently control the transmission of ions, thereby maintaining the normal functional activities of cells such as material exchange, signal transmission, and energy exchange. Inspired by ion channels, artificial ion channels that respond intelligently to external fields have potential applications in micro-nano devices, drug delivery and release, and biosensors. Among them, photoresponsive artificial ion channels, which can convert light signals into multiple detectable signals, thereby realizing remote and non-destructive in situ control, have attracted extensive attention. Traditional light-responsive artificial ...
