Abstract

A film of poly (L-lactide)(PLLA) and carboxymethyl starch (CMS) is prepared by casting evaporation method. The use of CMS blended with PLLA induces the porous film that is potentially used in tissue engineering applications. PLLA is blended with CMS in solution form and rolled on glass to produce a film. The film is then irradiated with gamma-ray (γ) at 10 and 80 kGy. FTIR analysis indicates weak interaction between PLLA and CMS at 10 kGy. Degradation and crosslinking are predicted to have occurred simultaneously at 10 kGy and massive degradation at 80 kGy as indicated in differential scanning calorimetry (DSC) curves. Mechanical analysis shows a higher strength at 10 kGy indicating that crosslinking has occured whereas degradation takes place at higher doses as shown in the reduction of mechanical strength for both PLLA and PLLA/CMS.
