Inorganic/organic hybrid polymers
… and characterise a range of inorganic/organic hybrid polymers containing pendant vinyl groups and to study their uses as possible fire retardants. The work consisted of several parallel strands: the synthesis of organically modified silicas; the preparation of vinyl containing silsesquioxanes …

Switching hybrid polymers with physically and covalently entrapped organic photochromes
… work was to test and tailor new sol gel derived hybrid polymer coatings for the incorporation of photochromic spirooxazines and chromenes. The development and optimisation of work was performed via two different routes (dye and matrix ones), that led to photochromic multi-layer coating systems …

Structure-property correlations in fluoroaryl functionalized inorganic-organic hybrid polymers for telecom applications
… ORMOCER® materials (inorganic-organic hybrid polymers) for optical waveguide applications in telecommunication is presented. The preparation of the materials included precursor silane synthesis, hydrolysis/polycondensation of organoalkoxysilane mixtures, and photolithographic processing …

Nanostructured gene and drug delivery systems based on molecular self-assembly
… of a new family of linear-dendritic "hybrid" polymers with plasmid DNA for applications in gene therapy. It begins with an overview of the design of next-generation, non-viral gene delivery systems and continues through the synthesis and validation of hybrid polymer systems, which …

Triplet-Triplet Annihilation Upconversion in Solid-State Organic-Inorganic Ureasil Polymer Hosts
… TTA-UC systems based on organic-inorganic hybrid polymers known as ureasils as hosts for a range of sensitizer/emitter pairs over the solar spectrum. Ureasils consist of organic poly(oxyalkylene) chains covalently linked to an inorganic siliceous network via urea bridges. A library of …

Characterization of a Novel Dynamic Combinatorial Depsipeptide System with Implications for the Origin of Biopolymers
… of these monomers to form functional covalent biopolymers under simulated early Earth conditions has proven difficult, if not impossible. A further complication is that the peptide bonds holding proteins together are not easily broken in plausibly prebiotic settings, a kinetic limitation that …

Understanding and Preventing the Degradation of Silicon as a Lithium Ion Battery Anode
… the thin-film electrode. These inorganic-organic hybrid polymers are synthesised from simple starting materials, allowing the functionalisation with various organic side-groups to tune their properties. The polymer synthesis and deposition of thin polymer films are described in detail and the film …

NOVEL SOFT SURFACES WITH INTERESTING SURFACE AND BULK MORPHOLOGY
… object from the surface of these triblock copolymers have been measured. Results obtained from laboratory scale experiments have been verified by static immersion tests performed in the marine environment, involving the removal of adhered soft and hard fouling organisms. Gaining insights on …
