Solid state coagulation of optical quality polymer thin films |
| abstract |
A method for preparing optical quality, thin films of polymers and co-polymers, as well as blends of such polymers or co-polymers with flexible polymers and co-polymers which comprises n (a) preparing a solution of the polymer or co-polymer or blend in a suitable solvent; n (b) forming a film from the solution; n (c) cooling the thus-formed film to a temperature below the freezing point of the solvent; and n (d) dissolving the solvent out of said film at a temperature below the melting point of the solvent. n This method can be employed to prepare films of high optical clarity for electro-optical device applications. Because of their thermal stability, mechanical strength and chemical resistance, films prepared according to this method can also be used as filters and separation membranes. |
