Synthesis and characterization of linear and non-linear copolymers. Study of the mechanical properties and their conductivity for lithium-ion battery applications

In this research work, linear homopolymers and copolymers were synthesized, along with miktoarm star copolymers bearing polyanionic chains, where lithium is used as the counter cation, with potential use on solid polymer electrolytes, as additives or polymer matrices.
At first, the synthesis of STFSIK monomer was conducted, and its polymerization through NMP techniques afforded linear homopolymer samples. As a result, linear homopolymers PSTFSIK, of various molecular weights were synthesized, while a polymerization kinetic study took place, using a specific NMP alkoxyamine initiator. Subsequently, the lithiated form of the polymers, PSTFSILi, was obtained via an ion – exchange reaction.
Likewise, by the simultaneous polymerization reaction of styrene and STFSIK, a series of linear random copolymers PS-co-PSTFSIK/Li was created, in which the effect of the PSTFSILi weight fraction content was evaluated on the thermal properties of the samples, that were characterized with comparable degree of polymerization.
For the synthesis of the miktoarm star copolymers, a polyethylene oxide star macroinitiator was synthesized, which was then subsequently employed for the NMP polymerization of STFSIK, or in other case STFSIK and St.
The miktoarm star copolymers PEO/PSTFSILi produced, were also studied in terms of their ionic conductivity and their mechanical properties to be evaluated as materials that could potentially be used in lithium-ion batteries.
