Abstract

Suspensions of titania nanoparticles in benzyl alcohol were synthesised from TiCl4 by means of non-hydrolytic sol-gel (NHSG) process. The stable suspensions were mixed with an aliphatic epoxy resin and subsequently photo-polymerised in the presence of a cationic photo-initiator to produce transparent composite films. The presence of titania didn't influence significantly the polymerisation rate, while a progressive decrease in the maximum value of epoxy groups conversion was observed by increasing the titania content. Gel content analysis demonstrated that all organic species (benzyl alcohol and corresponding by-products) were covalently linked to the epoxy network, suggesting that both 'active chain end' and 'activated monomer' mechanisms were active during the propagation step in the cationic ring-opening polymerisation. The presence of titania increased significantly both glass transition temperature and modulus (in the rubbery region) confirming the reinforcing and stiffening effect due to both the presence of inorganic nanofillers and, most importantly, a higher cross-linking density of the composite material with respect to the pristine epoxy matrix. Nano-indentation and scratch tests also showed a systematic increase of hardness and scratch resistance by increasing the filler content. © 2011 Elsevier Ltd. All rights reserved.

Abstract

In the present paper a comprehensive analysis on the preparation and characterization of organic–inorganic hybrids containing perfluoropolyethers (PFPE) as organic component and silica ( in situ generated from tetraethoxysilane by means of the sol–gel process) as inorganic counterpart is reported. PFPE with different molecular weights and functionalities have been used in order to improve the miscibility with respect to other reactants and solvents comprising the final formulation of the coating. In this respect, PFPE oligomers have been used with or without chain extension with polycaprolactone segments. The hybrids have been applied with different techniques onto glass substrates as functional coatings and the effects of different molecular structures, molecular weights and organic–inorganic ratios have been thoroughly investigated in terms of surface properties (i.e. water and oil wettability and surface segregation of PFPE segments).
