“…3 The operating frequency is a function of how quickly the electrical double layer is formed, which is a function of ion conductivity in the PIL. 1,4 The ion conductivity of the PIL can be tuned with the polymer architecture, the choice of counterions, and the glass transition temperature (T g ) of the PIL. 5−7 For example, compared to random copolymers, the preparation of the block copolymers, with an ionic (PIL) block, will commonly result in microphase separation, 8−10 providing effective domains for ion transport and overall improvement in mechanical properties.…”

1,2,3-Triazolium-based polyionic liquids (PILs) were made by a copper-catalyzed azide−alkyne cycloaddition (CuAAC) "click" reaction from poly(4-vinylbenzyl chloride). The click reaction facilitates the design and manipulation of the polymer architecture by selecting the desired alkynes, the azide-containing moieties, and the alkylating group of the 1,2,3-triazole group. Using this versatile chemistry and design, we prepared PILs with comblike homoand block copolymer architectures using bistrifluoromethanesulfonimidate (TFSI-) as counterions. The block copolymer self-assembles into an ordered morphology. The block copolymer was integrated into metal−insulator−metal capacitors and found to display a prominent electrical double layer when characterized by electrochemical impedance spectroscopy.

Well-defined fluoropolymers exhibit unique properties such as excellent oil and water repellency, satisfactory thermal stability, low refractive index, and low surface energy.The origin of these properties is attributed to the presence of strong electronegative and low polarizable Fluorine atom in the backbone of such polymers which leads to a strong C F bond (with a high bond dissociation energy of 485 kJ mol −1 ). Due to these features, these polymers have found applications as functional coatings, thermoplastics, biomedical items, separators and binders for Li-ion batteries, fuel cell membranes, piezoelectric devices, high quality wires and cables, etc. Usually, fluoropolymers are synthesized by conventional radical (co)polymerization of fluoroalkenes which leads to the production of (co)polymers with ill-defined end group, uncontrolled molar mass, and high dispersity values. In the last two decades, significant developments of various reversible deactivation radical polymerization (RDRP) techniques have helped the design of macromolecular architectures (including block, graft, star, dendrimers) on demand. However, for relevant new applications, well-defined fluoropolymers with well-defined macromolecular architectures (e.g. block copolymers as thermoplastic elastomers and electroactive polymers or graft copolymers for fuel cell membranes) are required.Several RDRP methods developed in the last couple of decades have paved the way for the synthesis of (co)polymers with well-defined molar mass, dispersity, chain end-functionality and

Nitroxide mediated polymerization (NMP), sometimes known as stable free radical polymerization (SFRP), is considered one of the main types of reversible deactivation radical polymerization (RDRP) that have emerged as a major advance in polymer synthesis in the past 30 years. This review examines NMP's development from a uniquely Canadian perspective. Inspired by reports of a reversible equilibrium between the TEMPO persistent radical and a growing polymeric radical chain, researchers at the Xerox Research Centre of Canada (XRCC) reported radical polymerizations of styrene with hallmarks typically associated with living polymerizations: linear degree of polymerization of with conversion, narrow molecular weight distributions, and ability to re‐initiate the chain end with additional monomer. This effort expanded to polymerizations in dispersed aqueous media (eg, miniemulsion) and to polymerizations directed for various architectures (block, graft, star), but NMP was ultimately generally limited to styrenic monomers. Consequently, NMP trailed other RDRP methods, such as atom transfer radical polymerization (ATRP) and reversible addition fragmentation transfer polymerization (RAFT), due to its limited monomer choice. With the advent of second‐generation alkoxyamine initiators, however, the range of monomers polymerizable in a controlled manner greatly expanded to include acrylates, acrylamides, and eventually methacrylates (under certain conditions), providing renewed impetus towards using NMP. Consequently, Canadian researchers applied these new alkoxyamines for more versatile polymers, resulting in products such as stimuli‐responsive polymers, CO2‐switchable latexes, bio‐hybrid composites, organic photovoltaic materials, and photolithographic materials. The chronological progression of the developments in NMP from various Canadian laboratories highlights these achievements in new polymeric materials.
