abstract = {Herein, we report on the synthesis of a systematic library
of vinyl ether-based poly(ethylene oxide) (PEO) side-chain
copolymers in order to reduce the crystallization of PEO.
The influence of different grafted PEO side chain lengths,
the grafting density, and the [Li+]:[EO] ratio after mixing
with LiTFSI on the glass transition temperature (Tg), the
crystallinity, and the resulting ionic conductivity was
examined. Copolymers bearing longer PEO side chains and
higher grafting densities show higher crystallization
tendencies while their Tg is reduced at the same time.
Furthermore, the addition of LiTFSI reduces crystallization
but increases Tg. Because these effects are directly
impacting the ionic conductivity, we demonstrate that the
different parameters need to be carefully adjusted in order
to balance their influence. In this way, a fundamental view
that shows the potential of PEO side-chain copolymers for
their applications as polymer electrolytes is provided.},
