Abstract:

PLA/starch composite foams were prepared by reactive extrusion and the influences of the content of starch、AC、maleic anhydride、BPO and screw speed on the properties of the foams were discussed. The results showed that the starch content was better to be lower than 20%, or it would have unfavorable effect on foamability. AC content should be 3phr~4phr, MAH and BPO could improve the compatibility of the composite system so that foam performance was improved, screw speed should be kept in 100rprm~200rpm.
