Microwave‐assisted green approach for graft copolymerization of <scp>l</scp>‐lactic acid onto starch
Abstract
<jats:title>ABSTRACT</jats:title><jats:p>Poly <jats:sc>l</jats:sc>‐lactic acid grafted starch (St‐<jats:italic>g</jats:italic>‐PLA) copolymers were directly synthesized under microwave irradiation by using sodium hydroxide (NaOH) and stannous 2‐ethyl hexanoate acting as a catalyst, without the use of toxic solvents. The product were characterized by Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance (<jats:sup>13</jats:sup>C CP/MAS NMR), X‐ray diffraction (XRD), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA‐DTG). SEM analysis indicated that microwave heating had a considerable effect on the interfacial adhesion between PLA and starch. Thermogravimetric analysis (TGA‐DTG) revealed that copolymers exhibited better thermal stability. Maximum PLA grafting was achieved with the following reaction conditions: 450W microwave power, monomer ratio of 1:5 and 0.4<jats:italic>M</jats:italic> of NaOH. This study demonstrates that it is possible to obtain St‐<jats:italic>g</jats:italic>‐PLA copolymers with better processing characteristics and smaller sizes via microwave‐assisted synthesis. The applied procedure is an interesting “green” synthesis method for the production of biodegradable materials used in a diverse range of applications. © 2015 Wiley Periodicals, Inc. J. Appl. Polym.
