Ever-increasing requirement, the ecology potential of organic electro-optic device must obtain bigger promotion and attention.
The chief component of organic electro-optic device is thin-film material (such as insulating barrier, semiconductor layer, encapsulated layer and conductive layer
Etc.), and at this stage often there is waste of material (such as spin coating), equipment cost height in the solwution method technique for film processed material
The shortcomings of (such as slot coated).No matter for industrial point of view or scientific research angle, a kind of energy large area processing, energy are needed badly now
Automated production, low cost, low consumption, easy-operating technique produce the film needed for organic electro-optic device.
The content of the invention
The present invention seeks in view of the shortcomings of the prior art, there is provided a kind of new flexible scraper for film preparation
Coating process, by dosage (the 1-2 μ L/cm for reducing coating material2) and reduce process complexity to reduce cost.Can be simple
By increase the size of flexible scraper realize large area process.This method has more preferable processing compatibility and redundancy
Degree, and the processing of different materials can be carried out simply by flexible scraper is changed, there is the versatility having very much and process compatible
Property.
The present invention is achieved by the following technical solutions：A kind of flexible scraper coating method for film preparation, bag
Include using following equipment：Flexible scraper (13), scraper fixing device (14), displacement platform (15)；The sample to be coated is located at position
Move on platform (15) plane；The scraper fixing device (14) is located between flexible scraper (13) and displacement platform (15) with solid
Determining flexible scraper (13) does not allow it to come off；Institute's translation stage (15) connection flexible scraper (13) and ensure scraper horizontal direction with
Sample plane is parallel, by the flexible scraper (13) by self gravitation on sample with sample surfaces gentle touchdown.
By preparing one layer of barrier layer, by the surface on barrier layer and flexible scraper contact so that the thickness using barrier layer
Remove the thickness of film needed for controlling.Barrier layer is dispensed when preparing ultrathin film material.
The barrier layer is to have certain thickness any materials insoluble in solution used in following process.It is suitable by selecting
Flexible scraper, control the size of flexible scraper, realize the large area processing of organic electro-optic device (sample) film；Change flexible
The material of scraper, operation is coated to it to adapt to a variety of materials.
Flexible scraper is put down gently in sample surfaces, ensures flexible scraper surface with sample by scraper Action of Gravity Field gentle touchdown.
By selecting the parameter of suitable displacement platform, solvent volatilization and the life of film are controlled by the movement of scraper
It is long.Institute's translation stage translational speed is controllable, moving direction is controllable.
The film of the organic electro-optic device includes：Insulating barrier, organic semiconductor layer, encapsulated layer and conductive layer etc. are various thin
Membrane material.
The scraper fixing device is any sticky stuff that can be fixed on flexible scraper on displacement platform or had
The fixation bayonet socket design of said function.
Methods described includes：Institute's translation stage (15) connects flexible scraper (13) and ensures that its horizontal direction is put down with sample
OK；In displacement platform upper blade fixing device by the fixation of the flexible scraper one end made, ensure that flexible scraper will not fall off；
Appropriate solution is dripped in the line that sample contacts with flexible scraper, is scraped using the control device movement flexibility of displacement platform
Knife, adjust direction and speed；
With the movement of scraper and the continuous volatilization of solvent, it can be formed and the thin of thickness is determined by barrier layer and solution solid content
Membrane material.
Beneficial effects of the present invention：The flexible scraper coating process of the film preparation of offer, there is advantages below：
1. a technique can use minimal amount of material (1-2 μ L/cm2) to complete the making to film, material is effectively reduced
Cost.
2. can realize that large area is processed by increasing the size of flexible scraper in a technique, can be scraped by changing flexibility
Knife carries out the processing of different materials, effectively reduces equipment cost and consumables cost.
3. in this technique process, using flexible light weight scraper, make flexible scraper and sample using itself Action of Gravity Field
Product surface gentle touchdown and be unlikely to destroy surface, suitable for the device film preparation of various structures, there is good universality.
4. a technological operation is simple, cost of labor can be effectively reduced.
Brief description of the drawings
Fig. 1 is that the flexible scraper technique for the film preparation that the present invention is implemented is coated with the schematic diagram of certain thickness material；
Fig. 2 is the schematic diagram of the flexible scraper technique coating ultra-thin materials for the film preparation that the present invention is implemented.
Embodiment
Embodiment of the present invention is described more fully below in conjunction with the accompanying drawings.
The flexible scraper technique of film preparation provided by the invention is coated with schematic diagram such as Fig. 1 institutes of certain thickness material
Show, the barrier layer (11) is covered on sample (10), and the film (12) of the organic electro-optic device is covered on sample；Institute
State flexible scraper (13) by self gravitation on sample with sample surfaces gentle touchdown；The scraper fixing device (14) is located at
With fixing flexible scraper (13) between flexible scraper (13) and displacement platform (15)；Institute's translation stage (15) connects flexible scraper
(13) and ensure that its horizontal direction is parallel with sample 10.By the volatilization of the mobile control solvent of scraper, so as to generate needs
Thin-film material, film thickness are together decided on by the thickness on barrier layer and the solid content of solution.It is thin with organic polymer insulating materials
Exemplified by film coating, benzene class organic solvent can be generally used, scraper speed can use 1cm/s.
The schematic diagram of the flexible scraper technique coating ultra-thin materials of film preparation provided by the invention is as shown in Fig. 2 when painting
When cloth ultra-thin materials (such as semiconductor layer, interface-modifying layer), can simply dispense barrier layer (11), remaining keep with it is upper
State unanimously, due in the absence of barrier layer, contact printing can be completed so as to realize the coating of ultra-thin materials.With organic molecule half
