摘要:
A powder for sustained release of a gas including a hydrophilic core, a hydrophobic layer on an outer surface of the hydrophilic core, and particles in contact with the hydrophobic layer. The hydrophobic layer contains an acid releasing agent. The particles contain an anhydrous material capable of binding with water. The core, the particles, and the hydrophobic layer are substantially free of water, and the core is capable of generating and releasing a gas after hydrolysis of the acid releasing agent.
摘要:
The present invention provides novel thermoset copolymers, and methods for preparing same, having both the strength and the thermo-oxidative stability required for high performance, high temperature applications. The copolymers comprise (a) a thermoplastic resin having unreacted phenolic OH groups, and (b) bis-oxazoline monomers which have been modified to have at least one substituent on the oxazoline ring selected from the group consisting of a methyl group, a group having at least a substituent capable of undergoing addition polymerization, and a cyclic group capable of undergoing ring opening polymerization.
摘要:
A method of electrophoretic deposition of adsorbent media onto an electrically conducting substrate. The adsorbent media may include one or more porous coordination polymers and/or one or more secondary adsorbing particles. The adsorbent media may be continuously applied from a liquid composition at a selected thickness and at a controlled rate and as a function of voltage profiles.
摘要:
A composition for energy-controlled generation and release of at least one gas, which includes an energy-activated catalyst capable of being activated by electromagnetic energy, and a solid or a liquid containing anions capable of being oxidized by the activated catalyst or reacted with species generated during activation of the catalyst to generate at least one gas. The composition, when exposed to electromagnetic energy, is capable of generating and releasing the gas after activation of the catalyst and oxidation or reaction of the anions.
摘要:
A particle including anions dispersed throughout an amorphous, paracrystalline or crystalline solid solution, the anions being capable of reacting with hydronium ions to generate a gas. The particle can be incorporated into a powder capable of generating and releasing a gas after hydrolysis of an acid releasing agent.
摘要:
A composition for retarding bacterial, fungal and viral contamination and mold growth containing an acid releasing polymer, a hydrophilic material, and chlorite anions. Each component of the composition has a particle size of not more than about 1,000 angstroms. The composition is substantially free of water and capable of releasing chlorine dioxide upon hydrolysis of the acid releasing polymer.
摘要:
A composite for retarding, killing, preventing or controlling microbiological contamination includes a hydrophilic material containing an .alpha.-amino ether, .alpha.-amino alcohol or .alpha.-amino ester and a chlorite salt, and a hydrophobic material containing an acid releasing agent. The hydrophilic and hydrophobic materials are adjacent and substantially free of water, and the hydrophilic material is capable of generating and releasing chlorine dioxide after hydrolysis of the acid releasing agent.
摘要:
A multilayered composite for providing sustained release of chlorine dioxide includes a hydrophobic layer containing an acid releasing agent, and a hydrophilic layer containing chlorite anions. The hydrophilic and hydrophobic layers are adjacent and substantially free of water, and the hydrophilic layer is capable of releasing chlorine dioxide upon hydrolysis of the acid releasing agent.
