Description
Technical field
The utility model is related to a kind of mutual capacitance touchscreens functional sheet and preparation method thereof, for handset touch panel etc., category
In touch-screen research field.
Background technology
Current capacitive touch screen is due to stable performance characteristics, and rapid substitution resistive touch screen is touched as the market mainstream
Screen structure is touched, common conventional capacitive formula touch-screen uses ITO+PET+OCA (tin indium oxides+poly terephthalic acid second two substantially
Alcohol ester+optics acrylic is without base material double sided optical glue) made for raw material；
Due to PET non-refractories and ultraviolet, heat distortion temperature is 70 degree, and moisture-proof is poor (saturated water absorption is 0.6%)；
Easily softening is rotten under 40 DEG C of high temperature above states, can reduce the capacitive sensing amount of whole capacitance type sensor, thus influences whole
Body touches effect, simultaneously because moisture-proof is bad, uses such a structure condenser type touch-screen, aqueous vapor meeting in severe rugged environment for a long time
Conductive layer is slowly entered, causes the problems such as metal is migrated, conductive layer sensing sensitivity is reduced.It mainly has following problem, due to
PET materials are limited, and the optimum working temperature of capacitance plate is 5 DEG C~35 DEG C, and working relative humidity 30%~90% is unsatisfactory for work without condensation
Make to be possible to that " drift " phenomenon occurs during environment.The storage temperature of capacitance plate is -20 DEG C~60 DEG C, in high temperature or low temperature ring
Stored in border, transport may also damage capacitance plate.Optimal use temperature is 5 DEG C~35 DEG C, and such a capacitance plate compares fearness high temperature,
It is exposed to the sun or is placed in for a long time in the hot environment more than 40 DEG C for a long time under sunshine, it is possible to permanent damages capacitance plate.
Simultaneously because easy scratch surface in pet sheet face not scratch-resistant, actual production process, and it is used as touch-control to show base
Bottom, must be requested that outward appearance is good, thus PET construction capacitance touch screen, there is also surface tear problem, is reduced in manufacturing process
Whole capacitance touch screen processing procedure yields.
Therefore existing market main flow capacitive touch screen is mainly used in mobile phone, computer, flat board, wrist-watch etc. mainly indoors
On the smart machine used in normal temperature environment, it is impossible to be used for a long time in outdoor or other severe rugged environments (such as inside automobile), this
Also the use to capacitive touch screen brings a definite limitation, it is impossible to promote the extensive utilization of capacitive touch screen.
Graphene (graphene) is the only one layer of atomic thickness for being stripped out, being made up of carbon atom from graphite material
Two dimensional crystal.2004, Univ Manchester UK physicist An Deliegaimu and Constantine's Nuo Woxiao loves,
Graphene is isolated in success from graphite, it was demonstrated that it can be with individualism, and therefore two people also obtain Nobel's thing in 2010 jointly
Neo-Confucianism prize.Graphene is both most thin material, is also most tough material, 200 times more taller than best steel of fracture strength.
It has good elasticity again simultaneously, and stretch range can reach the 20% of own dimensions.It is that current nature is most thin, intensity highest
Material, if making hammock with the graphene of one piece of 1 square metre of area, weight itself just can bear one less than 1 milligram
One kilogram of cat.Graphene most potential application at present is the substitute as silicon, ultra micro transistor npn npn is manufactured, for producing
Following supercomputer.Replace silicon with graphene, the speed of service of computer processor will be fast hundreds times.On the other hand,
It is very fine and close, even minimum gas atom (helium atom) can not also be penetrated.These features cause it to turn into many science
Family is as the conception of the raw material of transparent electron product, such as transparent touch display screen, luminescent screen and solar panel.But
It is to implement its application, it is still necessary to carry out breakthrough effort.
