Preparation method of organic-inorganic hybrid transparent mesoporous gel monolith

Abstract

The invention discloses a preparation method of organic-inorganic hybrid transparent mesoporous gel monolith, belongs to the technical field of mesoporous molecular sieve functional materials, and particularly relates to a preparation method of organic-inorganic hybrid transparent mesoporous gel monolith which is large in size, crack-free and optically transparent and provided with pore walls modified by ethylidene. The preparation method is characterized by comprising the following steps of: by using 1,2-bis(triethoxysilane) ethane as a single silicon source, rapidly synthesising the organic-inorganic hybrid transparent mesoporous gel monolith provided with pore walls modified by ethylidene by controlling a component proportioning ratio and the conditions of system gelation in an acidic medium taking a nonionic surfactant as a template. The preparation method of the material is simple, and easy to operate; the product is regular in shape, controllable in size, and good in heat stability and transparency; and modifying groups are uniformly distributed in the pore walls of the transparent mesoporous gel monolith and unable to block pore channels. The preparation method has an important application value in the field of development for novel optical devices.

Description

technical field

[0001] The invention discloses a method for preparing an organic-inorganic hybrid transparent mesoporous gel monolith, which belongs to the technical field of mesoporous molecular sieve functional materials, and specifically relates to a large-sized, crack-free, optically transparent organic-inorganic hybrid mesoporous gel monolith. Preparation method of colloidal monolith. Background technique

[0002] The transparent mesoporous gel monolith formed by surfactant as a template has high light transmittance, low external area, and its inherently ordered and adjustable pore structure can make dye molecules, photosensitive molecules, semiconductor particles Or conductive nanowires and other guest molecules can be intercalated at a higher concentration without mutual aggregation between molecules, so they have broad application prospects in the development of new optical devices.

[0003] However, as the host material of transparent mesoporous gel monolith, its p...
