| 20120108689 | PROCESS FOR FORMING A POROUS PVA SCAFFOLD USING A PORE-FORMING AGENT - The present invention relates to a process for forming a porous poly(vinyl alcohol) (PVA) scaffold using a pore-forming agent, and more particularly, to a process for forming a porous PVA scaffold using a pore-forming agent, comprising: mixing PVA with the pore-forming agent to form micropores in the PVA scaffold and using an easily decomposable pore-forming agent after the formation of the pores to improve convenience and reduce the processing time in manufacturing the porous PVA scaffold as well as to enable a pore size and porosity to be selected. A process for forming a porous PVA scaffold using a pore-forming agent according to the present invention includes heating to melt the PVA, cooling the melted PVA and mixing the PVA with a heat-decomposable pore-forming agent, repeating the freezing/thawing of the mixed PVA to cure the PVA mixture, and stirring the cured PVA mixture with a hydrochloric acid solution at a high temperature of 65° C. or more to produce foam. | 05-03-2012 |
| 20100028430 | MATERIAL AND MANUFACTURING METHOD OF BIOACTIVE PROTEIN-CALCIUM PHOSPHATE COMPOSITE - Disclosed are a bioactive protein-calcium phosphate ceramic composite for surface modification of a substrate for use as a substitute in the treatment of musculoskeletal disorders, and a preparation method thereof. The bioactive protein-calcium phosphate ceramic composite is prepared by mixing an aqueous solution of calcium phosphate and a protein, and impregnating the calcium phosphate and the protein in the resulting aqueous solution to co-precipitate them on a substrate, such as metals, ceramics and polymers, wherein the substrate is patterned, and different proteins are impregnated in at least two regions of the patterned regions. | 02-04-2010 |
