Fig. 2From: Characterisation of a novel poly (ether ether ketone)/calcium sulphate composite for bone augmentationSEM micrographs of a fracture surface of a 20%PEEK/80%CS specimen prepared at a P:L ratio of 0.85 g/mL (a) prior to heat treatment and (b) after heat treatment. (c) FT-IR spectra between 500 cm−1 and 4000 cm−1 wavenumbers of PEEK and CSH (CaSO4.0.5H2O) starting powders, and a powdered 20%PEEK/80%CS specimen after heat treatmentBack to article page
