▎ 摘 要
Amine-functionalized graphene nanoplatelet (GNP-A) was reinforced in a blend matrix of diglycidyl ether of bisphenol-A (DGEBA) and polystyrene-block-poly(ethylene-ran-butylene)-block-polystyrene (PSPEB) via facile solution approach. Diaminodiphenylmethane was employed as hardener. According to SEM, inclusion of pristine GNP enhanced surface roughness, however, autumn leaf like pattern was observed in amine-functional nanocomposite. For 0.1 wt.% pristine GNP loading T-max was observed as 545 degrees C, whereas GNP-A showed higher value (553 degrees C). Glass transition temperature of amine-system was also higher (230 degrees C) than pristine one (224 degrees C). DGEBA/PSPEB/GNP-A 0.1 depicted semi-crystalline nature (12.6 degrees and 19.8 degrees). EMI shielding effectiveness of nanocomposite was sufficiently high i.e. approximate to 18.87-20.15 dB.
