The main aim of this research was the generation of new intelligent materials, in this case thermoreversible material, based on an epoxy matrix modified with liquid crystal for optoelectronic application. The samples were prepared by the reaction‐induced phase separation (RIPS) of a solution of 4′‐(hexyloxy)‐4‐biphenyl‐carbonitrile (HOBC) and polystyrene (PS) in diglicydylether of bisphenol‐A epoxy resin (DGEBA). The systems were cured with a stoichiometric amount of an aromatic amine hardener, 4,4′‐methylene bis(3‐chloro‐2,6‐diethylaniline) (MCDEA). Taken into account results obtained by differential scanning calorimetry (DSC) and transmission optical microscopy (TOM) equipped with a hot stage it was found that depending on morphology generated by RIPS of HOBC/thermoplastic particles in the epoxy matrix thermally reversible light scattering (TRLS) material can be obtained.
