Abstract
AbstractIn this article, we present fabrication of ecofriendly, biodegradable and printable polyester films using polyethylene glycol, lactic acid and maleic anhydride as monomers. The susceptibility of polyester films towards biodegradation was tuned by varying lactic acid concentration. Films with 0.5 moles concentration of lactic acid exhibited maximum susceptibility towards degradation i. e. 39% in 60 days. Experimental results revealed that the films were printable with ink, label and stamp printing. The films were durable for tape and solvent test and capable of retaining dye on their surface owing to polar interactions between dye molecules and carboxylic groups of polymer chain ends.
