Novel Approaches To The Synthesis of Clicked Block Copolymers
Block copolymers are widely used in both the academic and industrial communities due to their unique properties. With the development of living polymerization techniques, the synthesis of block copolymers with controlled molecular weights and unique architectures has reached an all time high. Here …

Functional Materials and Device Concepts for Magnetic Sensing, Gas Detection and Energy Harvesting
… combines flexible, tunable magnetostrictive polymer composites with an electret to form a scalable capacitive sensor for low-field detection. The second avoids magnetostrictive materials by using permanent magnets to induce mechanical strain and piezoelectric transduction to generate the …

Mixed-gas Transport in Microporous Polymer Derivatives for Energy-Efficient Gas Separations
… materials formulations that address these polymer-specific disadvantages. Polymers of intrinsic microporosity (PIMs) were designed as ultrahigh-free-volume materials with inefficient chain packing and high surface areas, resulting in pure-gas performance beyond that of traditional glassy …

Cyclopentadiene as a Platform for Polymer Synthesis and Modification of Macromolecular Systems
… substituent on the terminal diene rings. Polymerizations with 1,4- and 1,3-diethynylbenzene afforded linear Diels-Alder polyphenylenes (DAPPs) having lateral tert-butyl and perfluoro-4-tolyl substituents. The perfluoro-4-tolyl-substituted DAPPs are thermally stable, glassy solids (Tg ~ 230 …

Synthesis and evaluation of quadruple hydrogen-bonding modules for smart materials applications
… derivatives that can be incorporated into polymers and onto surfaces. A method for the synthesis of non-symmetric diamidonaphthyridines from bromonaphthyridines using copper catalysis with aqueous ammonia at ambient temperature and pressure is detailed in chapter two. Chapter three relates …

Polymer-based Graphene Oxide Derivatives as a tunable multi-purpose platform
… Waals forces, thus making difficult any further functionalization of the carbon platform. Instead, the top-down approaches involve Graphite as raw material. Among the available synthesis methods, the most diffused ones employ oxidation and exfoliation procedures of Graphite to obtain Graphene …
