| 英文摘要 | The structure and rheological properties of carbon-based particle suspensions, i.e., carbon black (CB), multi-wall carbon nanotube (MWNT), graphene and hollow carbon sphere (HCS) suspended in polydimethylsiloxane (PDMS), are investigated. In order to study the effect of particle shape on the structure and rheological properties of suspensions, the content of surface oxygen-containing functional groups of carbon-based particles is controlled to be similar. Original spherical-like CB (fractal filler), rod-like MWNT and sheet-like graphene form large agglomerates in PDMS, while spherical HCS particles disperse relatively well in PDMS. The dispersion state of carbon-based particles affects the critical concentration of forming a rheological percolation network. Under weak shear, negative normal stress differences (Delta N) are observed in CB, MWNT and graphene suspensions, while Delta N is nearly zero for HCS suspensions. It is concluded that the vorticity alignment of CB, MWNT and graphene agglomerates under shear results in the negative Delta N. However, no obvious structural change is observed in HCS suspension under weak shear, and accordingly, the Delta N is almost zero. |
