Sub- material, laminated film can be made up of the film of multiple layers of different materials, therefore laminated film can be made to have multiple material concurrently
Partial properties, assign the more combining properties of laminated film.At present, laminated film is widely used in packaging field, due to THIN COMPOSITE
Film has pliability strong, and mechanical property is excellent, the low feature of production cost, researcher gradually by laminated film apply sensor,
The field such as ultracapacitor and functional fibre, still, traditional laminated film surface is all smooth, exists and compares surface
The small shortcoming of product, it is impossible to preferably realize sensing, conductive, the function such as absorption.
The content of the invention
To solve problem above, it is an object of the invention to provide a kind of porous compound film and preparation method thereof, this is porous
Laminated film has the characteristics of specific surface area is big.
To achieve the above object, the technical scheme designed by the present invention is：
Porous compound film, including basement membrane, the outer surface of the basement membrane are pasted with outer layer porous membrane, and the outer layer is porous

With one kind in polyamide, the outer layer porous membrane is one kind in polypropylene, polyethylene, polyester and polyamide；The base
The thickness of film is 50~100 μm, and the thickness of the outer layer porous membrane is 50~100 μm.
Preferably, the outer layer porous membrane is same material with basement membrane.
The preparation method of porous compound film, comprises the following steps：
1) outer layer copolymer in mass ratio, is weighed：Acetylbutyrylcellulose is 6.5:3.5~9:1, conduct after being well mixed
Outer layer film raw material, double-deck cast film machine is put into by outer layer film raw material and basement membrane polymer, through double-deck cast film machine extrusion, is unidirectionally drawn
Stretch and be cooled and shaped the laminated film for obtaining being overlapped after process by basement membrane and outer membrane；The outer layer copolymer is polypropylene, gathered
One kind in ethene, polyester and polyamide；The basement membrane is one kind in polypropylene, polyethylene, polyester and polyamide；
2) laminated film is soaked in acetone soln, after acetylbutyrylcellulose in acetone extract outer membrane, outside
Tunic formation outer layer porous membrane, porous compound film is obtained after drying.
Preferably, the outer layer copolymer is same material with basement membrane polymer.Outer layer copolymer polymerize with basement membrane
Thing be porous compound film made from same material in two membranes composite effect more preferably, attaching it is tighter.
Preferably, outer layer porous membrane thickness is 50~100 μm, basement membrane thickness is 50~100 μm.
Preferably, the average diameter of the outer layer porous membrane Hole is 1~10 μm.
Preferably, the mass ratio of the outer layer film raw material and basement membrane polymer is 1:1~2.
The advantage of the invention is that：
1, compared with traditional composite membrane, outer membrane of the invention is outer layer porous membrane, and the specific surface area of outer layer is expanded
Big tens times, the porous compound film has micron-sized pore space structure, if being handled by functional materials, this is micron-sized
Pore space structure can adsorbed close functional materials so as to realizing special function, it is such as conductive, it is hydrophilic, it is hydrophobic, you can be spun special
Knitted fabric, is sensed, and the field such as ultracapacitor is applied.
2, after being combined by double-deck cast film machine, the composite effect of outer layer porous membrane and basement membrane is good, without viscous glutinous agent.
3, outer layer copolymer：Acetylbutyrylcellulose is 6.5:3.5~9:When 1, acetylbutyrylcellulose by and point
It is dispersed in outer layer copolymer, by blending extrusion one-way drawing, and continuous phase can not be formed, it is by acetone that acetate butyrate is fine
After dimension element extraction, outer membrane formation pore space structure, so as to form porous compound film.If mass ratio is more than 9:1, outer layer is porous thin
Hole diameter in film is too big more than 10 μm, influences the sensing or adsorption function of porous compound film；If mass ratio is less than 6.5:
3.5, blended extrusion one-way drawing can produce the acetylbutyrylcellulose of continuous phase, nanofiber is formed after acetone extract
Structure and pore space structure can not be formed.
