摘要:This invention relates to a novel class of hybrid lipid compound based on pentaerythritol, their intermediates, preparation methods and uses thereof. Different kinds of functional groups such as alkyl chain, siloxane group, azobenzene, porphyrins, cholesterol, benzene ring and carboxyl were introduced into the four hydroxyl groups of pentaerythritol through chemical reaction to obtain the final hybrid lipid compounds based on pentaerythritol. Cerasomes prepared from such lipids have uniform size, silicate network surface, good stability and biocompatibility, and the leakage of drugs is not easy. The present liposome can be used as functional materials such as drugs or drug carriers, or used for optical storage and molecular devices, simulation, design and synthesis of artificial systems, nano-composite membrane materials and the removal of organic pollutants, etc., in addition, the preparation method of the present invention is simple, and it is easy for industrial production.

摘要:Organic-inorganic hybrid materials using lignin as the organic phase for the synthesis of thin films are described. These hybrid materials are prepared through the known sol-gel method whereby a metal-oxide precursor and alkoxysilane functionalized lignin are used and subsequently processed to obtain coatings and thin films with a high content in lignin.

摘要:A preparation method of thermadapt shape memory polymers includes: (1) synthesis of pendant hydroxyl groups functionalized epoxy oligomer using epoxy resin and alcohol amine; (2) synthesis of alkoxyl groups terminated silane crosslinking agent by isocyanate silane coupling agent and diamine; (3) crosslinked shape memory polymers were prepared by condensation reaction of pendant hydroxyl groups functionalized epoxy oligomer and alkoxyl groups terminated silane crosslinking agent. The thermadapt shape memory polymers show high glass transition temperatures and high tensile strength. The original shape of thermadapt shape memory polymers can be reconfigured to a new permanent shape as needed, and thus effectively solving the bottleneck problems of reprocessing or reshape in the traditional crosslinked polymers once after molding. The thermadapt shape memory polymers are suitable for smart materials based on shape memory polymers with complex three-dimensional permanent shapes, and showing unfolding or folding behaviors along with convert to three-dimensional structures under heat stimulation.

摘要:This invention relates to a protected organotin-based catalyst system for polyurethane synthesis that is useful in coatings applications. The catalyst has low activity in the absence of oxygen. When a coating mixture comprising the catalyst is sprayed and/or applied to a substrate as a thin film in air, the catalyst is activated. For solvent-based refinish systems comprising hydroxyl and isocyanate species at high solids levels, the catalyst system therefore provides extended viscosity stability, i.e., pot life.
