Selective Chemical Etching of a Rod-Coil Triblock Copolymer Containing Poly(9,9-didodecyl fluorene-2,7-diyl) and Poly(D,L-lactide) |
| 초록 |
A series of symmetric, semi-crystalline triblock copolymers of poly(D,L-lactide)-b-oligo(9,9-didodecyl fluorene-2,7-diyl)-b-poly(D,L-lactide) (PLA-b-PF-b-PLA) were synthesized by using ring opening polymerization method. Selective chemical etching was performed on the thin films of PLA-b-PF-b-PLA, spin-coated on the Si substrate with different rpms. Prior to chemical etching, the spin-coated films were completely dried and annealed under the atmospheres of selective solvents. These solvent-annealed films were chemically-etched by aqueous NaOH solution which selectively removed the PLA blocks of PLA-b-PF-b-PLA. The surface topologies of the spin-coated films of PLA-b-PF-b-PLA were carefully monitored by atomic force microscopy (AFM) and transmission electron microscopy (TEM). |
