Thermal Motion of Isolated Poly(tert-butyl methacrylate) Chains on Solid Substrates |
| 초록 |
A better understanding of the dynamic behavior of polymer chains at solid interfaces is crucial in terms of their inherent scientific interests as well as technical applications. We here observed the thermal motion of isolated poly(tert-butyl methacrylate)(PtBMA) chains on hydrophilic and hydrophobic silicon substrates by atomic force microscopy (AFM). The apparent long-range diffusion of chains was observed on the hydrophobic substrate, while such was not on the hydrophobic one. This mobility difference of PtBMA chains on the two substrates should be arisen from the difference of the interfacial interaction via the existence of the adsorbed water layer. We will discuss the effect of humidity on chain mobility during the AFM observation. |
