Disclosed is a method for preparing a bilayer scaffold through single process comprising: preparing a first polymer aqueous solution; adding a second polymer into the first polymer aqueous solution and stirring a reactant; adding a surfactant into the stirred reactant and stirring the reactant at high temperature and high speed; freeze-drying the stirred reactant thereby obtaining a sponge; dipping the sponge in a cross-linking agent thereby rendering be cross-linked; and freeze-drying the cross-linked reactant.

A catalyst complex for catalysis of degradation of a polymer material is described. Said complex comprises a magnetic particulate body containing iron oxide at its surface with an average diameter of 150-450 nm, and a plurality of catalytic groups grafted onto the iron oxide surface of the magnetic particulate body, which catalytic groups comprise a bridging moiety and a catalyst entity, wherein the bridging moiety comprises a functional group for adhesion or bonding to the iron oxide surface and a linking group towards the catalyst entity, and wherein the catalyst entity comprises a positively charged aromatic heterocycle moiety, and a negatively charged moiety for balancing the positively charged aromatic moiety.

The present invention relates to binder compositions with improved amine components, and a method of manufacturing a collection of matter bound by said binder compositions.

Disclosed are latexes, suspensions, and colloids having a cationic antimicrobial compound complexed with an anionic surfactant. The surfactant may have greater affinity for the antimicrobial compound than other anionic surfactants and other anions in the latex, suspension, or colloid that contribute to disperse phase stability to prevent disrupting the dispersions. Dispersions containing the antimicrobial compound may therefore have a shelf life comparable to dispersions that are otherwise identical but lack the cationic antimicrobial compound and its complexed anionic surfactant. Coatings made with the complexes can exhibit essentially undiminished antimicrobial activity.

A solid, ionically conductive, non-electrically conducting polymer material with a plurality of monomers and a plurality of charge transfer complexes, wherein each charge transfer complex is positioned on a monomer.

The present application relates to a curable composition. The present application provides a curable composition comprising an internal heat source for generating heat by application of an alternate-current magnetic field from the outside, together with a phthalonitrile compound and a curing agent therefor. The curable composition can precisely control the heat generated from the internal heat source according to the strength of the alternate-current magnetic field to precisely control curing conditions of the curable composition.
