Abstract
The present disclosure is related to a non-volatile thermotropic composite material comprising a first component comprising a non-aqueous and non-volatile proton donating material; a second component comprising a monomer, an oligomer or a polymer as a proton accepting material; a non-volatile polymeric matrix; and wherein the non-volatile polymeric matric, the first component and the second component are configured to maintain at least one property which is reversibly changeable based on thermal energy received by or given out from the non-volatile thermotropic composite material. Proton donating materials include ionic liquid, poly(ionic liquid) and deep eutectic salt. The proton accepting material comprises at least an ether, a phenyl ester, an amide and an acrylate functional group. Also disclosed is a method of making said composite material comprising providing the first and second components and a non-volatile polymeric matrix and curing the mixture to form the non-volatile thermotropic composite material. The non-volatile thermotropic composite material can be used in smart windows.
