Preparation of Fe-doping PMP foam
With ferrocene as dopant, Fe-doping PMP foams were prepared by thermal-induced phase inversion. The actual density values of doped foams are higher than the theoretical ones, and increase gradually from top to bottom. At a constant theoretical density, the actual densities of doped foams reduce with Fe content increase. Compared with PMP foam, the size of pore and skeleton of the doped PMP foam is bigger.
