Description
Technical field
The present invention relates to the preparation method of a kind of antistatic film, the system of a kind of CNT antistatic film
Standby, belong to field of new.
Background technology
Antistatic film refers to add in the film certain antistatic material to reduce film surface resistance, thus plays anti-
Electrostatic interaction, it is to avoid operation element or human body are caused damage by thin film because piling up electrostatic.
Antistatic film is widely used at numerous areas particularly electronic applications.And CNT antistatic film by
In having good anti-static effect, developed the most rapidly.Prepare it is critical only that of CNT antistatic film embedding
The quality of CNT thin layer (hereinafter referred to as carbon nano-tube film) on the membrane surface.
The method preparing carbon nano-tube film at present mainly has arc discharge method, chemical vapour deposition technique, electrophoretic deposition
Deng.Wherein, arc discharge method and electrophoretic deposition are required for high temperature action, and energy consumption is big, cost is high, complicated process of preparation；Chemistry
Vapour deposition process industrially has begun to application, but sample purity prepared by this method is the highest, affects the performance of antistatic film；
The spraying that document " in the preparation of carbon nano-tube film and the research of performance thereof " is mentioned can be prepared with the spin coating method of combining
Bright conductive carbon nanotube thin film, the dehydrated alcohol dissolved with CNT is placed in ultrasonic cleaner by this method, to CNT
Disperse, then sprayed to prepare on quartz glass substrate carbon nano-tube film, but the shortcoming of this method is to divide in liquid
Dissipating the nanotube dispersion obtained and secondary agglomeration easily occurs in dry run, the electric conductivity making thin film is the best, it is impossible to meet
Antistatic is required high occasion.
The present invention is that the gas-phase carbon nanotube dispersion using gas phase dispersion method to produce prepares carbon nano-tube film, gas phase
Nanotube dispersion is the flue dust shape microgranule formed after a kind of CNT disperses, and ties in spatial networks on a microscopic level
Structure, has the features such as density is low, light transmittance is high, good conductivity.Owing to the dispersion effect of this gas-phase carbon nanotube dispersion is good, gram
Having taken employing solution dispersion easily makes CNT that the shortcoming of secondary agglomeration occurs after the drying, can be applicable to gas phase, solid phase, liquid
In the production technology of phase environment, it it is the ideal material preparing permanently antistatic thin film.
Summary of the invention
For above-mentioned the deficiencies in the prior art, and unique advantage based on gas-phase carbon nanotube dispersion, the present invention provides
A kind of method utilizing CNT to prepare antistatic film.
The technical solution adopted in the present invention is a kind of method preparing CNT antistatic film, specific implementation process
Comprise the steps:
(1) thin film is placed on bottom expansion chamber so that it is surfacing and free from admixture；
(2) gas-phase carbon nanotube dispersion dispersion produced is guided to introduce in expansion chamber by air-flow；
(3) the gas-phase carbon nanotube dispersion in expansion chamber can be through methods such as natural sediment, Electrostatic Absorption, gas shocks
It is attached on film surface, forms one layer of finely dispersed CNT thin layer, by controlling gas-phase carbon nanotube dispersion
Concentration and sedimentation time, can regulate and be adsorbed onto gas-phase carbon nanotube dispersion on film surface；
(4) the gas-phase carbon nanotube dispersion adsorbed on thin film and thin film are carried out cured, surface can be used
Adhere to or the method for double roller hot rolling.
The invention has the beneficial effects as follows: provide a kind of low cost, (film surface resistance can reach conductor model to high-performance
Enclose), the preparation method of high (the can reach 80%) antistatic film of light transmittance, the thin film of preparation can play permanently antistatic
Effect, and disclosure satisfy that the occasion high to antistatic requirement.
