Curing reaction of azomethine epoxy liquid crystals

Abstract

The aromatic epoxy N,N-bis[4-(2,3-epoxy propoxy)benzylidene]-1,4-phenylenediamine (AZ-1) with mesogenic properties was synthesized and cured in the presence of 4,4’-methylene-bis(3-chloro-2,6-diethylaniline) (MCDEA) or 2,7-diaminofluorene (DAF) as the curing agents. The curing reactions were studied by differential scanning calorimetry (DSC), polarized optical microscopy (POM) and wide-angle X-ray scattering. The product obtained in the curing reaction of AZ-1/MCDEA mixture shows a texture of smectic-like structure. The curing reaction of AZ-1/DAF mixture led to a heterogeneous structure, without liquid crystalline properties.
