Abstract
Official abstract text for this publication.
The present invention provides a method for preparing a composition comprising porous ceramic, comprising the following steps: (a) synthesizing poly(N-isopropylacrylamide-co-methacrylic acid) (p(NIPAAM-MAA)) or similar thermo-response compound thereof; (b) mixing a dispersant with hydroxyapatite or calcium phosphate salt; (c) mixing the p(NIPAAM-MAA) of the step (a) or similar thermo-response compound thereof with water to obtain a hydrogel solution; (d) mixing the hydrogel solution of the step (c) and product of the step (b) to produce a mixture; (e) adding macromolecular particles to the mixture of the step (d) and stirring to produce a slurry; (f) filling the slurry of the step (e) into a template slot; and disposing the template slot filling with the slurry of the step (f) on a crucible, then proceeding high temperature sinter in a furnace to form the composition comprising porous ceramic.
