Titanium dioxide nano paper and preparation method thereof

Abstract

The invention relates to a Titania nanometer paper and the preparation method, the key component of the Titania nanometer paper is a Titania nanometer belt or the Titania nanometer belt and additive;the Titania nanometer paper mainly includes the preparation method as follows: dispersing, filtrating and drying. Compared with the common nanometer membrane and the nanometer particle, the nanometerpaper has a more predominant performance of simple making method and low cost. The nanometer paper is capable of being widely used in the aspects such as high temperature filtration, electron device and photocatalysis, etc. the invention has the advantages of rational design, simple technics, thin fibre, even aperture, good filtering quality and high temperature performance, in addition, the invention is capable of directly being cut, utilizing the average effect of the nanometer belt performance, fundamentally solving the practicality problem of the single nanometer belt device.

Description

technical field [0001] The invention relates to a titanium dioxide nano-paper and a preparation method thereof, belonging to the field of preparation of inorganic nano-materials. Background technique [0002] Titanium dioxide, as a semiconductor material with various functional properties, has important applications in electronics, photocatalysis, photoelectric conversion, gas sensing and biosensors. At present, titanium dioxide used for the above purposes generally exists in the form of nanoparticles or thin films. Due to the disadvantage of difficult recovery of nanoparticles, the application cost is relatively high. Compared with other forms of nanomaterials, titanium dioxide thin films not only have high preparation temperature , high cost and other disadvantages, and because the device can only use the surface effect, the sensitivity and other properties are greatly reduced compared with one-dimensional and two-dimensional nanomaterials, and cannot be popularized and ap...

Problems solved by technology

It is true that very sensitive devices can be fabricated by using a single nanoribbon, but in the process of device fabrication, electrodes must be prepared by photolithography and micro-welding by focused particle beams. Expensive large-scale equipment, and more importantly, no matter which method is used to prepare the nanoribbon material, there will be a certain difference in size, and this small difference in structure will bring significant differences in device performance

Therefore, it is difficult to standardize the preparation of nanoribbon devices, and it is also difficult to put them into practical use.

A single nanomaterial device has brought great difficulties to the industrial application of nanobelts. How to make use of the characteristics of titanium dioxide nanobelts to prepare nanodevices has become a difficult problem in front of people.
