Reinforcement of shear thickening by polystyrene-polyacrylamide particles |
| 초록 |
Shear thickening(ST) refers to the drastic increment of viscosity that occurs when a high shearing force is applied to certain concentrated colloidal suspensions. For ST behavior, the hydro-cluster mechanism is accepted as a mechanism,in which inter-particle interaction is important. To enhance inter-particle interactions, we prepared functionalized polystyrene particles with polyacrylamide surface(PS-PAAm particles). We introduced PS-PAAm particles as abundant hydrogen bonding donor. The effect of PS-PAAm particles on the ST behavior of mixed colloidal suspensions was investigated, the PS-PAAm particles affected ST behavior by enhancing inter-particle hydrogen bonding. |
