Reinforcement structure for rubber articles and methods of preparation
A reinforcement means for molded and extruded articles such as tires has a metal structure with a layer of silica gel bonded thereto. The silica gel bonds the reinforcement means to the rubber compound during the molding/vulcanization of the rubber compound without the need for a slow curing stage. The silica gel may be applied to the metal structure by a sol-gel process with the gel formed by drying the sol at a temperature up to 150 C. The reinforcement means is preferably a cable formed from steel wires coated with the silica gel. To further improve bonding of the silica gel to the rubber compound, an organosilane bonding agent may be included in the rubber compound or the reinforcing means provided with a second layer comprising an organosilane as a bonding agent. The reinforcement means are particularly useful for strengthening and providing geometric stability to tires.
Low temperature formation of perovskite films in supercritical fluids
Crystallization of perovskite films was performed in supercritical carbon dioxide with and without organic co-solvents. Post deposition crystallization of the films was performed in a binary, single phase supercritical fluid at constant conditions (45? C., 1200 psi) but with varying organic co-solvent volume fractions up to 2%. The co-solvents can provide selective interactions with one or both of the perovskite precursor compounds resulting in different film morphologies ranging from uniform films containing large grains to films exhibiting large cubic or hexagonal crystals or preferential crystallographic orientations. The use of supercritical fluids to enhance or tune crystallization in solid-state thin films could have broad applications toward the realization of high efficiency photovoltaic devices.
