- Abstract
Graphite reinforced polydicyclopentadiene (polyDCPD) composites were synthesized via the in situ ring-opening metathesis polymerization (ROMP) of DCPD with vapor-grown carbon fiber (VGCF), acidified multiwall carbon nanotube ( a-MWCNT), and mildly oxidized graphene oxide (MOGO) as distinctive reinforcing fillers, respectively. We studied the morphological effect of the fillers on the mechanical and thermal properties of graphite/polyDCPD composites. Mechanical property tests showed that the addition of VGCF greatly strengthened the tensile strength, the introduction of a-MWCNT dramatically extended the elongation at break, whereas the incorporation of MOGO enhanced both performances of the resulting composites. Impact tests showed that the maximum mechanical performances of a-MWCNT/polyDCPD and MOGO/polyDCPD composites both were got with 0.4 wt% of fillers ( a-MWCNT and MOGO) loading. Meanwhile, all of the reinforced composites exhibited increased thermal stabilities compared with the unfilled polyDCPD, confirmed by increased Tgs and thermal decomposition temperatures at 5 wt% weight loss.
