笼形倍半硅氧烷改性的层状双金属氢氧化物及其制备方法和应用
摘要：
本发明公开了一种笼形倍半硅氧烷改性的层状双金属氢氧化物及其制备方法和应用，制备方法具体为以笼形倍半硅氧烷、可溶性金属盐、水和无机碱为原料，采用机械化学方法，经一步改性制备得到；所述笼形倍半硅氧烷选自含有阴离子基团的笼形倍半硅氧烷。采用该方法制备得到的笼形倍半硅氧烷改性的层状双金属氢氧化物POSS‑LDH属于LDH家族中全新的一类。该新型POSS‑LDH具有纳米级片层结构，原生粒径约小于100nm，同时具有优异的热稳定性和阻燃性能。
摘要（英）：

The invention discloses a POSS (polyhedral oligomeric silsesquioxane) modified LDH (layered double hydroxide) as well as a preparation method and an application thereof. According to the specific preparation method, the POSS modified LDH is prepared from POSS, soluble metal salt, water and an inorganic base as raw materials through one-step modification with a mechanochemical method; POSS is selected from POSS containing anion groups. The POSS modified LDH POSS-LDH prepared with the method belongs to a brand-new type in the LDH family. The novel POSS-LDH is of a nanoscale lamellar structure and has excellent thermal stability and flame retardance, and the primary particle size is about smaller than 100 nm.
