发明名称 Supramolecular composite film material and method for fabricating
摘要 The present invention provides an optically anisotropic composite film material possessing improved working characteristics, including hydrolytic stability and mechanical strength with respect to environmental factors. These and other advantages of the present invention may be achieved by creating a supramolecular composite film material. This supramolecular composite film material comprises a matrix of thin crystal film composed of organic supramolecules containing polar groups, and a binding agent representing a water-soluble aliphatic compound containing at least two functional groups. The present invention further provides a method for manufacturing supramolecular composite film materials possessing these advantageous properties. In one embodiment, the method comprises the following steps: (i) formation of a layer of lyotropic liquid crystal composed of supramolecules of a cyclic organic compound with conjugated pi-systems and substituted polar groups; (ii) application of an external orienting force to said layer and further removal of a solvent with the resulting formation of a thin crystal film; (iii) treatment of the thin crystal film with a solution of inorganic salts leading to the formation of an insoluble crystalline film of supramolecules composed of said organic molecules; (iv) impregnation of said insoluble film with a binding agent capable of interacting with the polar groups with the subsequent formation of a filled film; and (v) drying of said filled film leading to the formation of a supramolecular composite film material.
