Preparation and characteristics of polyimide-TiO2 nanocomposite film

UV‐Curable Organic‐Inorganic Hybrid Film Coatings Based on Epoxidized Cyclohexene Derivatized Linseed Oil

“…From the results above and previous reports [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]18] about hybrid films, the properties of the hybrid films are TEOS oligomer concentration dependent. However, different systems have different optimum sol-gel precursor contents [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]18] which depend on the chemical structures of the organic and inorganic materials.…”

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] However, most of these coatings were thermal cured and not photo-polymerized. As photopolymerization of the organic phase is much faster than the hydrolysis of TEOS, [25] to facilitate a rapid formation of the inorganic network and to avoid volatilization of the TEOS monomers, TEOS oligomers were used instead of monomer.…”

“…Increased tensile strength, hardness and adhesion to metal substrate have previously been reported in hybrid coatings. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]18] Increased tensile strength and hardness have been attributed to the increased crosslink density, which has in turn been attributed to the interaction between the organic and inorganic phase. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]18] Both the ring opening polymerization of epoxidized cyclohexene derivatized linseed oil (ECLO) and the sol-gel reactions of TEOS oligomers were acid catalyzed, resulting in cocomitant curing of both the organic and inorganic phases.…”

“…However, different systems have different optimum sol-gel precursor contents [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]18] which depend on the chemical structures of the organic and inorganic materials. To balance the tensile properties, fracture toughness, hardness, adhesion, impact and abrasion resistance, 15 wt.-% TEOS oligomer content is the optimum for this UV-curing TEOS/ECLO system.…”

Investigation of Cure Reaction, Rheology, Volume Shrinkage and Thermomechanical Properties of Nano-TiO2 Filled Epoxy/DDS Composites

“…The TiO 2 is extensively used in industry, such as additives for epoxies, plastics, and rubbers [6,[26][27][28][29][30]. Moreover, TiO 2 filled polymers are well-known antimicrobial materials [31][32][33][34][35].…”
