Macromole aggegation attitude material is that the plasma polymerization of monomer source is the new way for preparing various film material with function with plasma chemical method.
The feature that the present invention is different with other plasma polymerizations be adopt molecular-weight average greater than 200 liquid, solid-state organism as monomer source, carry out polymerization with the lower paraffin hydrocarbons for work gas.
It is monomer source that the present invention has provided with solid paraffin (molecular-weight average 400); methane is the example of the plasma polymerization of work gas; that its product film has is infrared, visible, ultraviolet light transmission is high; hydrophobic nature is strong; high temperature resistant; corrosion resistant characteristics can be used as the anti-reflection protective film of infrared visible light speculums such as alkali halide metal infrared single crystal and gold, aluminium.
Description
Plasma polymerization is a kind of method of preparation organic functional thin film material, and the feature of prior art is to adopt the liquid substance of gas or small molecules (molecular weight is not more than 200) as monomer.Be that the plasma polymerization of raw material has obtained practical application widely at present with hydrocarbon, organosilicon, organic fluorine micromolecular monomer, but these monomers also have problems, mainly be that kind is limited, can be used as the monomeric hydro carbons of plasma polymerization, organic fluorine, organosilicon are few, easy implode of these gases or blast, transportation and use are all dangerous, and cost an arm and a leg, the cost height is restricted the application of plasma polymerization.
The present invention is that macromolecular substance is the plasma polymerization of monomer source, is the novel method of plasma polymerization.It unlike the prior art, main summary of the invention is:
With molecular-weight average greater than 200 solid or fluid organic material (comprising superpolymer), as its molecular-weight average organic fluorine and organosilicon greater than 200, hydro carbons and other are greater than 150 the organism monomer source as plasma polymerization, these materials are vaporized under heating under vacuum and/or action of ultrasonic waves, and enter the plasma reaction district.
2. polymerism does not take place in above-mentioned vaporized product under the action of plasma of rare gas elementes such as argon gas, but at lower paraffin hydrocarbons: as methane, ethane, polymerization reaction take place under the plasma effect of propane.The latter not only connects the monomer source vaporized product and polymerization, and because the polymerization velocity of itself is low, the polymerisate of gained of the present invention mainly reflects the constitutional features of monomer source material.
Be used or do not use rare gas element all can, for improving the chemical structure of product, can use NH in case of necessity

2Act as additional work gas Deng gas.
The present invention is at the solid, liquid attitude hydro carbons of various molecular weight, silicone based and organic fluorine class material has successfully carried out plasma polymerization when being monomer, general processing condition are 20～400 ℃ of monomer source temperature, radio-frequency power supply power 20～200W, flow of monomer 0.2～2l/min reactor pressure 20～500Pa.
Compare with existing plasma polymerization method, macromolecular substance of the present invention is that the plasma polymerization technology of monomer source has following advantage:
1. enlarged the raw material range of plasma polymerization, use this method, no matter be gas, liquid or solid, no matter be small-molecule substance or high-molecular weight polymer, various organism all can become the raw material monomer of plasma polymerization, thus the easier type material that synthesizes desired properties.
The product that obtains with the present invention with similar small molecule monomer products therefrom relatively, the former has many unique distinctions on structure, performance, performance is more superior, as the following example of giving.
3. all than gas safety, convenience, price is also more cheap in transportation is used for macromole solid, liquid attitude material.The present invention helps plasma polymerization further promoting the use in industry.
It is monomer source that the present invention has provided with solid paraffin (molecular-weight average 400), is the plasma polymerization example of work gas with methane.Typical experiment condition is 100 ℃ of temperature, radio-frequency power supply power 170W, methane flow 1l/min, reactor pressure 178Pa.This polymerisate film only has obvious absorption peaks at 3.4 μ m except that to the visible transparent in the infrared light district of 2.5～25 mum wavelengths, all the other transmissivities are greater than 98%(thickness 0.4 μ m); Hydrophobic nature is strong, and contact angle is 94.9 ° ± 0.5 °, is insoluble to common organic solvents, acid-and base-resisting corrosion, 279.5 ℃ of thermal weight loss starting temperatures, 321 ℃ of neutral temperatures (still air atmosphere).Can as metals such as the moisture-resistant protective membrane of alkali halide metal single crystal infrared window and gold, aluminium as seen, the gloss protective membrane of infrared light reflector.
Existing Plasma Polymerization prepares the article (Appt.Opt.14(1975) 2631 of infrared single crystal moisture-resistant protective membrane technology at R.H.Hopkins); the report of M.Shen (ADAO75008(1978)); the article of F.G.YAMAGISHI (Thin Solid.Films.84(1981) 427); the article of Guneri AKOVALI (J.Appl.Polym.Sci.32(1986) 4027) in reflection is arranged; be characterized in ethane being monomer, being equipped with rare gas element sometimes is carrier gas.Wherein the moisture-resistant protective capability at the ethane plasma polymer film of NaCl single-crystal surface deposit of the report of Guneri AKOVALI is: relative humidity RH=50～60% o'clock, destroyed in 100 hours.
The moisture-resistant protective capability of example of the present invention on the NaCl monocrystalline is: relative humidity RH=50～70% o'clock, and 15 days (360 hours) are after microscopic examination and infrared spectra confirm not have destroyed; Drip on the direct NaCl monocrystalline behind plated film, film destroy after general 2 hours preferably reaches 4 hours (thickness 0.4 μ m).
The technical characterstic that existing plasma polymerization method prepares metallic mirror gloss protective membrane is to do monomer with small molecules organosilicon or organic fluorine class to carry out polymerization; its product has strong absorption peak at region of ultra-red; so can only use at visible region; these technology are at patent DE-AS2537416; DE-OS2263480; among DE-DS2659143 and the DD216736 introduction is arranged; wherein the protection level that reaches of DD216736 is: anti-at least 260 ℃ of high temperature, the test of 0.2% soda lye did not have any destruction sign in 3 hours.
The present invention preparation be that the plasma polymer film of raw material can be used as metallic mirror protective membrane infrared, visible region with paraffin; at least can anti-260 ℃ of high temperature 90 minutes; 300 ℃ of high temperature 60 minutes; soaked 12 hours at 0.2% soda lye, and in 4% soda lye, soak again and do not see any destruction sign in 1.5 hours.
