Bonding and molecular environment effects on photoorientation in epoxy-based polymers having azobenzene units
Fernández Salvador, Raquel; Mondragón Egaña, Iñaki Bixintxo; Galante, María J.; Oyanguren, Patricia (Elsevier, 2009-03)An azo prepolymer (TAZ) was synthesized by reaction between Disperse Orange 3 (DO3) and diglycidyl ether of bisphenol A (DGEBA). The resulting TAZ was blended with DGEBA and two different monoamines, one aliphatic and ... -
Synthesis and characterization of epoxy polymers containing azobenzene groups that exhibit optical birefringence
Fernández Salvador, Raquel; Mondragón Egaña, Iñaki Bixintxo; Oyanguren, Patricia; Galante, María J. (2007-12-03)A push–pull azo dye (DO3) was used as photosensitive substance to satisfactorily synthesize new epoxy polymers containing azo groups covalently linked. Three different amines BA, TA and MXDA were used as hardeners. Materials ...
