Abstract
A kind of preparation method of thin polymer film, by will be by polyolefin master batch, isopropanol, graphene-Nano-meter SiO_22Composite material, odium stearate and dioctyl terephthalate mix and squeeze out to stretch by extruder being made, and thin polymer film of the invention is that a kind of safety is good, tensile strength is high, the film with good thermal conductivity and electric conductivity.
Description
Technical field
The present invention relates to a kind of thin polymer films and preparation method thereof.
Background technology
Thin polymer film is using organic high molecular polymer as film made of material.With the hair of petroleum industry and science and technology
Exhibition, the application field of thin polymer film constantly expand, and intelligent macromolecular membrane, high molecular functional have been developed to by initial packaging film
Film etc..It is selective diffusion barrier that wherein dosage is maximum, such as amberplex, micropore filtering film, ultrafiltration membrane, liquid film, liquid crystal
Film etc..There are nuclear fuel and metal smelting, gas separation, sea water desalination, ultra-pure water preparation, dirty useless processing, people in the field applied
The various aspects such as the manufacturing of work internal organs, medicine, food, agricultural, chemical industry.
Graphene is a kind of two dimensional crystal, and the common graphite of people is the planar carbon by being arranged from level to level with honeycomb-patterned ordered
Atom stack and formed, the interlaminar action power of graphite is weaker, it is easy to mutually stripping, form very thin graphite flake.When stone
After ink sheet stripping is at single layer, this is exactly graphene there are one the single layer of carbon atom thickness.The latest find of graphene is people
In terms of anticorrosion most efficient method.Common polymer coating is easy to be scraped off, and reduces protective value；And graphite
Alkene does protective film, has significantly delayed corrosion of metal speed, firmer antibody Monoclonal.Graphene is not only the new of electronic industry
Star, the future for being applied to traditional industry are also limitless.Its application direction：The fields such as marine anticorrosion, anti-corrosion of metal, heavy antisepsis.
Graphene has good heat conduction, electric conductivity.
