Effect of maleic anhydride and oxygen functionalized carbon nanotube on polyamide 6 and polypropylene blend properties

This work aims to investigate how adding functionalized carbon nanotubes (CNTs) to a Polyamide 6/polypropylene blend influences its properties. CNT functionalization was carried on through plasma with oxygen (CNT_O2) or maleic anhydride (CNT_MA). CNT_O2 presented the highest amount of oxygen, but, as the treatment time in plasma was twice as long as that of the CNT_MA sample, the oxygenated groups, for the most part, tended to formed lactones....
