All-covalent bond bonded inorganic-organic nano composite material as well as preparation method and application of all-covalent bond bonded inorganic-organic nano composite material
The invention relates to a novel all-covalent bond bonded inorganic-organic nano composite material as well as a preparation method and application thereof. The composite material is formed by bonding an inorganic substance as a continuous phase and an organic polymer as a dispersive phase through a covalent bond Si-O-Si and/or Si-O-C, wherein the inorganic matter is silicon oxide, silicon nitride or a silicon-oxygen-nitrogen matrix; the organic polymer is an organic polymer with at least one of active functional groups-OH,-COOH,-NH2 and-CH (O) CH-. In the structure of the inorganic-organic nano composite material, rigid silicon oxide, silicon nitride, a silicon-oxygen-nitrogen matrix and covalent bonds limit the movement of polymer chains and chain segments, so that the thermal stability of an organic polymer is remarkably improved, and the initial decomposition temperature of the composite material is improved by more than 100 DEG C compared with that of the organic polymer forming the material.
本发明涉及一种新型的全共价键键合的无机‑有机纳米复合材料及其制备方法和应用。其是以无机物为连续相，有机聚合物为分散性，两者通过共价键Si‑O‑Si和/或Si‑O‑C键合形成的复合材料；其中，所述无机物为氧化硅、氮化硅或硅氧氮基体；所述有机聚合物为具有活性官能团‑OH、‑COOH、‑NH2、‑CH(O)CH‑中至少一种的有机聚合物。所述无机‑有机纳米复合材料结构中刚性氧化硅、氮化硅、硅氧氮基体和共价键限制了聚合物链和链段的运动，从而显著提高了有机聚合物的热稳定性，复合材料的初始分解温度相对于构成该材料的有机聚合物提高了100℃以上。
