Abstract

The invention relates to a polystyrene / two-dimensional silica compound and a preparation method thereof. A laminar organic / inorganic composite two-dimensional laminar compound with regularly arranged halogens is taken as an initiator which is used to carry out an atom transfer free radical polymerization reaction with styrene so as to obtain the polystyrene / two-dimensional silica compound. The component and the method open a new way for realizing the design and synthesis of a composite material with novel performances.

Description
