    • It is an object of the present invention to provide a polyimide-based hybrid material which is industrially and advantageously utilized because of having better gas permeability, electric characteristics, heat resistance, mechanical strength, and the like as compared with the conventional polyimide-based hybrid materials, while keeping chemical resistance, forming characteristics (process characteristics), and the like inherently possessed by polyimide. Provided is a hyperbranched polyimide-based hybrid material constituted of an organic-inorganic polymer hybrid, wherein the organic-inorganic polymer hybrid has a hyperbranched polyimide moiety and an inorganic oxide moiety which are combining each other via covalent bond and constituting a composite structure.
    • 本发明的目的是提供一种与传统的聚酰亚胺类杂化物相比具有更好的气体渗透性,电特性,耐热性,机械强度等在工业上有利地使用的聚酰亚胺类杂化材料 材料,同时保持聚酰亚胺固有的耐化学性,成型特性(工艺特性)等。 提供一种由有机 - 无机聚合物杂化物构成的超支化聚酰亚胺系混合材料,其中有机 - 无机聚合物杂化物具有通过共价键彼此结合并构成复合结构的超支化聚酰亚胺部分和无机氧化物部分。
