含羧基侧基聚芳醚酮配位聚合物的制备与导热性能
Preparation and thermal conductivity of carboxyl-functionalized polyarylether ketone coordination polymers
摘要
Abstract
The polyaryletherketone(PEK-D)with rigid aromatic rings in the main chain and carboxyl groups precisely present at the side chains was successfully prepared through nucleophilic aromatic substitution reaction between 4,4'-bis(4-hydroxyphenyl)pentanoic acid(DPA)and 4,4'-difluorobenzophenone(DFK).The PEK-D-Fe3+and PEK-D-Cu2+coordination polymers were obtained through constructing the metal-carboxylate coordination networks with Fe3+and Cu+ions with the help of the strong coordination ability of deprotonated carboxyl groups.The disappearance of the characteristic carboxyl C=O peak and the present of the symmetric stretching vibration peak to carboxylate(—COO-)in the infrared spectroscopy confirmed the formation of coordination bonds between metal ions and carboxyl groups,and the fact that the carbonyl group in the main chain did not participate into the coordination.The results of Ultraviolet-visible absorption spectra indicated the emergence of LMCT transition pathways in the coordination system.The formation of coordination bonds significantly enhanced thermal properties,as convinced by the phenomenon that the glass transition temperature was enhanced from 178℃(PEK-D)to 254℃(Fe3+system),and further to 212℃(Cu2+system).Thermal conductivity measurements revealed that the thermal conductivity of Fe3+coordination system was 0.257 3 W/(m·K),and enhanced by 42.3％of PEK-D.The Cu2 coordination system also demonstrated a significant enhancement of 36.3％.关键词
