Abstract

The invention relates to T16 cage structure epoxy phenyl silsesquioxane and a preparation method thereof, and belongs to the technical field of organic-inorganic hybrid materials. The preparation method comprises the following steps: adding silane containing phenyl and epoxy groups and a solvent into a reactor, stirring, controlling the temperature of the reactor to be 25 DEG C, dropwise adding a catalyst namely a NaOH solution, controlling the temperature of the reactor to be 40 DEG C, and reacting for 1-2 hours to obtain a reaction solution; and adjusting the reaction solution to be neutral by using diluted hydrochloric acid, washing by using deionized water, drying, filtering, carrying out rotary evaporation on the filtrate, and drying to obtain the T16 cage structure epoxy phenyl silsesquioxane. The single T16 cage structure epoxy phenyl silsesquioxane containing 7 phenyl groups and 9 epoxy groups obtained in the invention has good thermal stability and reaction activity; and the preparation method is mild in condition, easy to control and suitable for expanded production.

Description

technical field [0001] The invention relates to a T16 cage structure epoxy phenyl silsesquioxane and a preparation method thereof, belonging to the scientific field of organic-inorganic hybrid materials. Background technique [0002] Polyhedral Oligomeric Silsesquioxane (Polyhedral Oligomeric Silsesquioxane, POSS) is a nanoscale organic-inorganic hybrid material at the molecular level. The shell composition of the organic substituents with different properties introduced by the atoms connected. The general structural formula of POSS is (RSiO 1.5 ) n , the value of n is generally 6, 8, 10 or 12, etc. R is a variety of organic substituent groups connected to silicon atoms, which can be inactive or active groups, and the connected R groups can be changed through organic chemical reactions to obtain Functionalized POSS for specific properties. POSS has the characteristics of low molecular density, low dielectric constant, small physical size, good organic compatibility and h...
