New Nanocomposites Findings Has Been Reported by
The news correspondents obtained a quote from the research, "The synthesis of poly (lactic acid)/clay nanocomposites was catalyzed by stannous octoate (SnOct(2)) and dibutyltindimethoxide (DBTM). The monomer to initiator ratio was kept at 2500:1 and the temperature was maintained at 150 degrees C. Three types of commercially available clays (Cloisite ® 30B, 15A, and Na+) were employed to study the effect of clay loadings on the polymerization of lactide and in situ formation of polymer-clay nanocomposites. The percentage yield decreased with increase in the clay loading from 0.1 to 5% for both Cloisite ® 30B and Cloisite ® 15A but no product was formed with Cloisite ® Na+ clay. The characterization of nanocomposites was done by using XRD (X-ray diffraction), TGA (thermo-gravimetric analysis), SEM (scanning electron microscopy) and TEM (transmission electron microscopy) analyses."
According to the news reporters, the research concluded: "This is the first report on the marked effect of clay mineral on in situ polymerization of lactide using microwave irradiation."
