Abstract

Novel star-branched organic-inorganic hybrid electrolyte based on the selectivity of the sequential triazine substitutions by using 2, 4,6-trichloro-1,3,5-triazine were prepared. The study aimed at developing highly conductive polymer electrolytes with sufficient mechanical strength and good solvent retention. The synthesis was based on the use of cynauric chloride as the central core to couple with triblock copolymer PPG-PEG-PPG diamine, and thereafter the crosslinking with epoxy alkoxysilanes. The use of cynauric chloride served as an excellent central core because of clear destination of the relative reactivity among three chlorides at different temperatures. The technique allowed for tailoring the copolymer structure and composition by judiciously selecting the starting amines and reaction conditions. The characterization of these hybrid electrolytes was performed using solid-state 29 Si and 13C NMR measurements.
