Method for producing plated component, plated component, catalytic activity inhibitor and composite material for electroless plating
A method for producing a plated part, includes: forming, on a surface of a base member, a catalyst activity inhibiting layer containing a polymer which has at least one of an amide group and an amino group; irradiating with light or heating a part of the surface of the base member on which the catalyst activity inhibiting layer is formed; applying an electroless plating catalyst to the surface of the base member heated or irradiated with the light; and bringing an electroless plating solution into contact with the surface of the base member to which the electroless plating catalyst is applied, to form an electroless plating film at a light-irradiated portion or a heated portion of the surface.
Nanomaterial of polyglycerol grafted cellulose nanocrystal dendrimer and preparation method thereof
The invention provides a nanomaterial of polyglycerol grafted cellulose nanocrystal dendrimer and a preparation method thereof. In the present invention, the cotton linter pulp is pulverized into flocculent fibers, fed to sulfuric acid, and reacted. After centrifugation, dialysis and ultrasonic cell disruption, cellulose nanocrystals are obtained. Carboxylated cellulose nanocrystals are further obtained after oxidation with TEMPO, dialysis, and freeze-drying. The carboxylated nanocrystals are further added to DMF, and under a nitrogen atmosphere, glycidol is grafted to the hydroxyl groups on the surface by heating with stirring. After the reaction is completed, the product is centrifuged, dried under vacuum, dialyzed, and freeze dried to obtain a nanomaterial of primary polyglycerol grafted cellulose nanocrystals. Dendrimers with different particle size ranges can be prepared by controlling the number of reactions, which contain a large number of hydroxyl groups on the surface, and are amenable to various modifications.

The arms on a star are covalently attached to the core of the star; each arm comprises one or more (co)polymer segments; and at least one arm and/or at least one segment exhibits a different solubility from at least one other arm or one other segment, respectively, in a reference liquid of interest.
Capsule for drug delivery systems of targeted tissue-specific delivery type using carbosilane dendrimer
The present invention relates to a targeting-type capsule for drug delivery systems. The present invention addresses the problem of providing a capsule for drug delivery systems by utilizing the reactivity of a thiol with an alkyl halide, wherein the capsule comprises a silole-containing carbosilane dendrimer and a labeling protein containing a target recognition site (e.g., green fluorescent protein), can include a biological polymer or another molecule therein, and can deliver the biological polymer or the like selectively into a target cell.
Method for preparing topological elastomers with highly branched structures, low modulus and high elasticity
A fabrication method and application of topological elastomers with highly branched structures, low modulus and high elasticity. The topological elastomers comprise dendritic macromolecules. The fabrication method includes direct crosslinking, post-crosslinking, grafting, and copolymerization. The performance of the elastomer can be easily tuned via changing the topology of the polymer network. The breakthrough of this invention lies in that these topological elastomers with highly branched structures are having low modulus and high elasticity, which would expand its application in the field of elastomer. Notably, the variety of topological elastomers, the versatility of curing chemistries, the availability of a wide variety of monomers, and the various polymerization methods are enabling the fabrication of topological elastomers with feasibility and efficiency.
