Patent number: 9296874
Abstract: A polymeric composition containing a polyacetal resin in conjunction with a blend of metal salts for reducing formaldehyde emissions. In one embodiment, the blend of metal salts comprises a metal salt of a fatty acid blended with a metal salt of a polycarboxylic acid. The metal salt of the fatty acid may comprise calcium propionate, while the metal salt of the polycarboxylic acid may comprise calcium citrate. The metal salts have been found to reduce formaldehyde emissions, especially when the composition contains a low gloss additive, such as acrylic polymer particles.

Patent number: 9242024
Abstract: The present invention provides a three-dimensional nanofibrous scaffold for tissue regeneration, which is increased in porosity and thickness to enlarge the surface area thereof, thereby enabling cell adhesion at a high density, and a method for fabricating the same. The method for fabricating a three-dimensional nanofibrous scaffold for tissue regeneration includes the steps of: (a) preparing a polymer solution; (b) preparing a nanofiber matrix, in which a plurality of nanofibers is entangled with each other, from the polymer solution prepared in step (a) using electrospinning; and (c) immersing the prepared nanofiber matrix in a solution and subjecting the solution to ultrasonication, thereby increasing the thickness and porosity of the nanofiber matrix.
