타이타니아 나노막대가 포함된 블록 공중합체 박막 표면의 전기장하에서의 불안정성 거동 연구 = Electrohydrodynamic Instability at Surface of Block Copolymer/Titania Nanorods Thin Film

다국어 초록 (Multilingual Abstract)

The influence of titania nanorods with an average diameter of 10 nm and an average length of 30 nm on the electrohydrodynamic instability of block copolymer (polystyrene-b-poly(2-vinylpyridine)) thin film was investigated in this article. The presence of titania nanorods increased the dielectric constant of the film, which resulted in a systematic reduction in the wavelength of the surface instability. Cross-sectional transmission electron microscopy analysis indicated that the migration/ aggregation of titania nanorods did not occur as a result of the applied electric field. This work can provide a simple route to the pattern formation using electrohydrodynamic instability with an aid of nanoparticles.
