英文摘要the structure and rheological properties of graphene-based particle (gp-x)/polydimethylsiloxane (pdms) composites are investigated as the surface oxygen content of graphene-based particle is varied, i.e., from 6.6% (gp-1) to 15.3% (gp-2), 25.5% (gp-3) and 43.1% (gp-4). interestingly, the dispersion state of graphene-based particles in pdms does not change monotonically with increasing surface oxygen content. the size of layered stacks and aggregates first decreases from gp-1 to gp-3 and then increases from gp-3 to gp-4 with increasing surface oxygen content. the larger size of layered stacks and aggregates in gp-1 and gp-4 suspensions results from strong inter-particle p-p and hydrogen bonding interactions. under weak shear, gp-1 and gp-4 form larger aggregates in pdms, which align along the vorticity direction, inducing negative normal stress differences (delta n) in the composites. however, gp-2 and gp-3 do not further aggregate under weak shear and the delta n is almost zero. it is further inferred that the strong inter-particle attractive interaction leads to the vorticity alignment of aggregates under weak shear.
