Abstract

The invention belongs to the technical field of organic and inorganic nano hybrid materials, and discloses a hollow microsphere based on methacrylic acyloxy cage-like silsesquioxane as well as a preparation method and an application thereof. The method comprises the following steps: preparing emulsion with stable methacrylic acyloxy cage-like silsesquioxane and Pickering effect, and drying the emulsion; soaking the dried emulsion by adopting a mixed solution which contains acetone and cyclohexane and serves as an etching agent so as to remove polystyrene nuclear to obtain a product. The product is extremely good in adsorption performance and can be applied to the field of sewage treatment. The operation technology is relatively simple, and experiment conditions are mild; the selected raw materials and reagents are easily obtained, and the yield of reaction is high.

Description

technical field [0001] The invention belongs to the technical field of organic-inorganic nano-hybrid materials, in particular to a microsphere with a hollow structure based on methacryloxy cage silsesquioxane (MA-POSS) and its preparation method and application. Background technique [0002] Cage silsesquioxane (POSS), also known as polyhedral cage silsesquioxane, is a general term for a class of silsesquioxanes with a lantern-like structure. According to the number of silicon atoms in POSS, they are also referred to as T for short. 8 -POSS([RSiO 1.5 ] 8 ), T 10 -POSS([RSiO 1.5 ] 10 ) and T 12 -POSS([RSiO 1.5 ] 12 ). The existing technology has synthesized high-yield, high-purity T 8 -MA-POSS and T 10 -MA-POSS, that is, methacryloxy cage silsesquioxane, and related articles are reported, such as articles by J.Peng et al. (J.Peng, K.Xu, H.L.Cai and J.C.Wu, RSC. Advances., 2014, 4, 7124-7131) and patent CN103214509A-cubic octamethacryloxypropyl silsesquioxane cryst...
