Figure 3

FTIR spectra of (A) BA scaffolds sintered at 900°C, (B) PEG-impregnated BA scaffolds sintered at 900°C (PEG-P900), (C) pristine PEG, (D) BA scaffolds sintered at 1000°C and (E) PEG-impregnated BA scaffolds sintered at 1000°C (PEG-P1000).

Note that most of the peaks of PEG and the untreated BA are present in PEG-P900 and PEG-P1000, indicating the strong adsorption of PEG in the scaffolds.
