제목 A ladder-type solid polymer electrolyte of Poly (hydroxymethyl 3,4-Ethylenedioxythiopene)-co-Poly(ethylene glycol) using the graft copolymerization
초록 A ladder-type solid polymer electrolyte of poly (hydroxymethyl 3,4-ethylenedioxydhiopene) (PHEOT) and Poly(ethylene glycol) (PEG) is synthesized using the graft copolymerization. PHEDOT uses as main frame of a new synthetic material and PEG as the rungs in this ladder structure. PEG molecular weigtht dependence of crosslinked PHEDOT-co-PEG network is evaluated through ionic conductivity and capacitance of PHEDOT-co-PEG. The sinsertion of the ionic salts into PHEDOT-co-PEG ladder structure lead to the enhancement of the ionic conductivity compared to PEG/LiClO4. The syenrgic effect may be explained as the more efficient segmental motion of the polymer chains or better electron mobility in the network due to relatively high crystallinity of PHEDOT frame.
