Structures and Relaxation Dynamics of Fluoroalkyl Block Copolymers in Selective Solvents |
| 초록 |
Due to the superhydrophobic nature and low refractive index, fluoroalkyl polymers can be excellent choice for multi-functional surface coating. Recently, we reported swelling-induced pore generation from the fluoroalkyl-containing block copolymer (F-BCP) films. Herein, we investigated the structures and relaxation dynamics of the self-assembled F-BCP structures using small-angle X-ray scattering (SAXS), small-angle neutron scattering (SANS), and dynamic light scattering (DLS). SAXS and SANS provided the equilibrium structures of spherical F-BCP micelles in selective solvents. DLS results confirmed that the relaxation dynamics is drastically affected by temperature within ambient range. This is supported by the fact that fluoroalkyl polymers have relatively low friction coefficients near the ambient temperature. Consequently, the film morphology and the pore volume fraction after swelling-induced pore generation were strongly dependent on temperature during the film preparation. |
