摘要: In the present work, a facile approach was employed to fabricate UV/heat dual-responsive triple shape memory polymer (SMP) by simply mixing Zn(Mebip)2(NTf2)2, metallosupramolecular unit formed coordinating 2,6-bis(N-methyl-benzimidazolyl)-pyridine (Mebip) ligands zinc di[bis(trifluoromethylsulfonyl)-imide] (Zn(NTf2)2), into one part of epoxy resin. Dissimilar previously reported UV sensitive SMPs with sophisticated molecular structure and relatively poor mechanical properties, advantage this is that UV-sensitivity achieved employing UV-heat transfer compound, matrix without significant sacrifice thermal properties. Also thanks light–heat nature Zn(Mebip)2(NTf2)2 segmented material structure, resulting displayed sensitivity composite part, while leaving neat SMP unchanged under source (solely sensitive). Thus an excellent heat selective localized effect.
