Abstract:
1. A method for preparing a composition comprising porous ceramic, comprising the following steps: (a) synthesizing poly(N-isopropylacrylamide-co-methacrylic acid) (p(NIPAAM-MAA)); (b) mixing a dispersant with hydroxyapatite; (c) mixing the p(NIPAAM-MAA) of the step (a) 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 polyethylene 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 (g) disposing the template slot filling with the slurry of the step (f) in a crucible, then heating the crucible in a furnace to form the composition comprising porous ceramic.
