dc.description.abstract본 연구에서는 항공기 방빙을 위해서 탄소계 소수성 입자인 탄소나노튜브의 코팅 횟수에 따른 테프론-폴리우레탄 탑코트의 나노입자 부착력과 표면 소수성 특성을 평가하기 위하여 실험을 진행하였다. 나노입자 부착력을 측정하기 위해서 인발접착시험을 진행하였고, 표면소수성 특성을 측정하기 위해서 정적접촉각 시험과 거칠기 평가를 진행하였다. 거칠기평가를 통하여 탄소나노튜브가 테프론-폴리우레탄 탑코트에 함침된 정도를 할 수 있었고, USB-현미경을 통하여 테프론-폴리우레탄 탑코트에 탄소나노튜브가 함침 및 분산정도를 확인하였다. 그 결과 코팅횟수가 많을수록 탄소나노튜브가 응집되고 이에 의하여 접착력이 감소한다는 것을 확인하였다. 실험결과 코팅 횟수에 따라 테프론-폴리우레탄의 소수성은 커지고 접착력은 감소하였다. 그로 인해 테프론-폴리우레탄 탑코트 와의 접착력 향상과 최적화된 소수성을 가지는 탄소나노튜브의 코팅횟수를 파악할 수 있었다.-
dc.description.abstractThis work presents an experiment study to evaluate the nanoparticle adhesion and surface hydrophobicity characteristics of Teflon-polyurethane top coat depending on the number of multi-wall carbon nanotube (MWCNT) coatings, which is a carbon-based hydrophobic particle. In order to measure the adhesion between the nanoparticles and the top coat, adhesion pull-off test was performed with different MWCNT oxidation times. Static contact angle and roughness measurements were carried out to characterize the surface hydrophobic behavior. Through the roughness evaluation, it was confirmed that the carbon nanotubes were wetted in the Teflon-polyurethane top coat, and the degree carbon nanotube wetting was confirmed through a USB-microscope. As a result, it was found that the larger the degree of wetting, the better the adhesion. From the experimental results, as the hydrophobicity of Teflon-polyurethane increased, the adhesive property decreased with the number of coatings. It was possible to improve the adhesive force and determine the number of coatings of carbon nanotubes with optimized hydrophobicity.-
