amorphous PEG nanodomains for effective transport. Larger domain spacing for the
hexagonally packed cylindrical PEG domains in brush-type architecture with the
suppressed PEG crystallization gives better room for the higher loading of Li + loading. Decoupling of T ODT and LC temperature by the virtue of higher molecular
weight of a polymer can help in better understanding of the role of LC clearing
temperature on the temperature-dependent anisotropic conductivity.
Topological change due brush architecture of PEG side chains containing block
can provide us following advantages over the block copolymer system with linear
PEG block:
(i) Suppression of PEG crystallization temperature for higher molecular weight
polymer sample to obtain amorphous nanodomains conducive for anisotropic
ion transport.
(ii) Larger PEG domains due to stretching of the backbone due to PEO side chain
crowding at higher molecular weights can help in higher loading of ions for
transport.
(iii) Presence of smectic LC structure within the block copolymer superstructure
with amorphous PEG domains for ion transport.
(iv) Higher molecular polymer system can be obtained to decouple T ODT and LC
clearing temperature which in turn can help in getting better understanding of
the effect of LC clearing temperature on the temperature-dependent
conductivity.
Apart from these advantages, presence of vinyl groups in the norbornene backbone after polymerization provides sites for further cross-linking to obtain mechanically robust system with entrapped amorphous domains for the ion transport to
realize the goal of solid-state electrolyte membranes.
LCBBC73–25 system thus can be efficiently utilized to study the temperature
dependence of anisotropic conductivity. It can help us to define parameter space to
obtain magnetic field-based assembly of such brush-type polymers. Effect of field
strength on the anisotropic conductivity at particular temperature can help us understand the practical relevance of these materials.
