Abstract

PLLA is a biodegradable polymer that is widely used in industrial and medical field. In this works, PLLA was mixed with 1-6 v/v% with (TIAC) to investigate the changes in tensile and strains properties of the PLLA film. PLLA commonly used as plasticizer or crosslinked agent to change the polymer property. PLLA and TIAC mixture was irradiated under 10 kGy doses for both of gamma (γ) and electron beam (EB). The results showed that the tensile strength (maximum stress) reduce with the increasing of TIAC amount in the PLLA but slightly increase at 4 v/v% TIAC addition for both irradiated and non-irradiated PLLA. Strain was found to increase at 2 v/v%. TIAC but decreased when more than 2 v/v% TIAC was added for irradiated PLLA. DSC results showed the changes in glass transition temperature, Tg, cold crystallization enthalpy, Hc, cold crystallization temperature, Tcand melting temperature, Tmindicate the changes in mobility of PLLA chain and crystallization regions with present of TIAC and ionizing radiation in PLLA. The changes in fourier transform infra-red (FTIR) absorptions peak indicate the penetrating of TIAC molecules into the PLLA chains.
