The method comprises the following steps: preparing an emulsion with a Pickering effect stabilized by methacryloxy cage silsesquioxane, and drying; using a mixed solution of acetone and cyclohexane as an etchant, and performing the above-mentioned emulsion after drying Soaking is performed to remove the polystyrene core to obtain the product. The product has good adsorption performance and can be used in the field of sewage treatment. The operation process of the invention is relatively simple, the experimental conditions are mild, the selected raw materials and reagents are relatively easy to obtain, and the reaction yield 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...
