Abstract
This invention relates in general to the formation of films having a controlled molecular orientation prepared from rod-like extended chain aromatic-heterocyclic ordered polymers, and containing a binder in the micro-infrastructure. Such films have high tensile strength, modulus, and environmental resistance characteristics.
Claims7
A polymer film comprising an ordered rod-like extended chain aromatic heterocyclic polymer selected from the group consisting of poly(p-phenylenebenzo bisthiazole) and poly(p-phenylenebenzo bisoxazole) having a binder selected from the group consisting of glass, ceramic, polysulfone, epoxy and polyimide interpenetrated in the microinfrastructure, and wherein the polymer is infiltrated with the binder to form a microcomposite of the polymer and binder.
A polymer film comprising an ordered rod-like extended chain aromatic heterocyclic polymer selected from the group consisting of poly(p-phenylenebenzo bisthiazole) and poly(p-phenylenebenzo bisoxazole having a binder precursor selected from the group consisting of glass, ceramic, polysulfone, epoxy and polyimide interpenetrated in the microinfrastructure, and wherein the polymer is infiltrated with the binder precursor to form a microcomposite of the polymer and binder.
A polymer film comprising an ordered rod-like extended chain aromatic heterocyclic polymer selected from the group consisting of poly(para-phenylenebenzo bisthiazole) and poly(para-phenylenebenzo bisoxazole), and a glass binder infiltrated within the polymer to form a microcomposite of the polymer and the binder.
A polymer film comprising an ordered rod-like extended chain aromatic heterocyclic polymer selected from the group consisting of poly(para-phenylenebenzo bisthiazole) and poly(para-phenylenebenzo bisoxazole), and a glass binder precursor infiltrated within the polymer to form a microcomposite of the polymer and the binder.
A polymer film comprising an ordered rod-like extended chain aromatic heterocyclic polymer having a binder selected from the group consisting of glass, ceramic, polysulfone, epoxy and polyimide interpenetrated in the microinfrastructure prepared by treating by shear a dope containing an ordered polymer to produce a microscale structure orientation therein, solidifying said microscale structure by coagulation in an aqueous medium, penetrating a binder precursor into the microstructure of said solidified polymer, and converting said precursor to said binder.
