The present study explores the possibilities of using locally available inexpensive waste prawn shell derived chitin reinforced and bioabsorbable polylactic acid(PLA)laminated composites to develop new materials with excellent mechanical and thermal properties for implantable application such as in bone or dental *** at different concentration(1e20%of PLA)reinforced PLA films(CTP)were fabricated by solvent casting process and laminated chitin-PLA composites(lctp)were prepared by laminating PLA film(obtained by hot press method)with CTP also by hot press method at 160*** effect of variation of chitin concentration on the resulting laminated composite's behavior was *** detailed physico-mechanical,surface morphology and thermal were assessed with different characterization technique such as FT-IR,XRD,SEM and *** FTIR spectra showed the characteristic peaks for chitin and PLA in the *** images showed an excellent dispersion of chitin in the films and *** analysis(TGA)showed that the complete degradation of chitin,PLA film,5%chitin reinforced PLA film(CTP2)and lctp are 98%,95%,87%and 98%respectively at temperature of 500*** tensile strength of the lctp was found 25.09 MPa which is significantly higher than pure PLA film(18.55 MPa)and CTP2 film(8.83 MPa).After lamination of pure PLA and CTP2 film,the composite(lctp)yielded 0.265e1.061%water absorption from 30 min to 24 h immerse in water that is much lower than PLA and *** increased mechanical properties of the laminated films with the increase of chitin content indicated good dispersion of chitin into PLA and strong interfacial actions between the polymer and *** improvement of mechanical properties and the results of antimicrobial and cytotoxicity of the composites also evaluated and revealed the composite would be a suitable candidate for implant application in biomedical sector.
