Milling Effects on Hybrid Collagen / Inorganic Phase Composites

Abstract:

Phospho-silicate glass powder consisting of particles sized up to 60 micrometers was incorporated into insoluble collagen by mechanical milling. After 8 hours milling at 180 rpm, the two phases are still separated. Increasing of mill frequency at 1800 rpm led to glass particles encapsulation in the collagen matrix after 90 minutes. The collagen structural properties after mechanical bonding to glass powder particles are investigated by vibrational spectroscopy in order to emphasize the milling effects upon the protein secondary structure.
