Composite materials were prepared by mixing in different proportions of hydroxyapatite (HA) and poly(ε-caprolactone-oxyethylene-ε-caprolactone) block copolymer (PCL-POE-PCL) to produce a new resorbable material for biomedical applications. This material has proved to be very interesting for production of periodontal membranes. Mechanical properties are linearly proportional to the amount of HA introduced. Fourier transform infrared (FTIR) investigations have pointed out that HA is able to… CONTINUE READING
