Tam sim no, polypropylene (PP) yog cov khoom loj tshaj plaws thiab siv cov thermoplastics, nrog cov hluav taws xob rwb thaiv tsev, tshuaj tiv thaiv thiab qaug zog, thiab lwm yam, qhov tsis zoo yog qhov kub thiab txias brittleness (brittleness kub -35 degree C), kev laus, Thaum tshav kub kub tsis kam thiab nplaim retardant tsis zoo, thiab PP cov khoom yas yog feem ntau ua rau cov khoom zoo li qub thiab hluav taws xob zoo li qub. Polypropylene yog dav siv nyob rau hauv tsheb qhov chaw, cov khoom siv hluav taws xob, cov khoom ntim, cov kav dej thiab cov khoom siv thiab cov khoom siv niaj hnub, thiab lwm yam. Cov tsis xws luag hauv kev ua kom sov, nplaim hluav taws kub thiab kev laus tiv thaiv kev siv cov polypropylene.
Graphene oxide (GO) qauv zoo ib yam li graphene, nrog cov qauv honeycomb morphology, muaj lub zog zoo thiab yoog raws, nrog rau qee yam ntawm cov hluav taws xob thiab thermal conductivity, thiab cov ntaub ntawv polymer los tsim cov khoom sib xyaw, nrog kev txhim kho toughening, txhim kho cov cua sov thiab tshem tawm lub luag haujlwm ntawm hluav taws xob zoo li qub.
Lub zog tensile thiab flexural zog ntawm graphene oxide-hloov cov ntaub ntawv PP nce zoo tshaj plaws thaum GO doping yog 0.4%.
Cov txiaj ntsig ntawm thermal conductivity thiab nplaim taws retardancy ntawm graphene oxide hloov PP cov ntaub ntawv qhia tau hais tias thermal conductivity λ ntawm graphene oxide hloov PP cov ntaub ntawv tau nce nrog nce ntawm GO doping. Qhov no yog vim GO nanoflakes muaj cov thermal conductivity zoo, thiab qhov nce hauv thermal conductivity loj dua ntawm 0.4% GO doping, uas yog 205.3% siab dua li cov qauv tswj. Qhov no yog vim lub fact tias GO nanoflakes yog uniformly dispersed nyob rau hauv lub PP resin los tsim ib tug nruam system, thiab cov tshav kub hloov tau zoo dua.
Ib yam li ntawd, cov nplaim hluav taws kub nyhiab ntawm graphene oxide-hloov PP tau nce ntau nrog cov doping ntawm GO, LOI ntawm PP yog 18. yog 0.4%, uas yog cov khoom siv hluav taws xob. Yog li ntawd, cov doping ntawm GO tuaj yeem ua rau cov thermal conductivity thiab nplaim taws retardant cov khoom ntawm graphene oxide hloov kho PP cov ntaub ntawv zoo dua, thaum doping tus nqi ntawm GO yog 0.4%, graphene oxide hloov PP cov ntaub ntawv muaj thermal zoo heev. conductivity thiab nplaim retardant zog.
