Properties of multi-walled carbon nanotube reinforced epoxy composites fabricated by using sonication and shear mixing
Min Ye Koo, Hon Chung Shin, Won-Seok Kim and Gyo Woo Lee 한국탄소학회 Carbon Letters 7 Pages
한국탄소학회 Carbon Letters 2014, Vol.15 No.4 4 255-261 (7 pages)
Multi-walled carbon nanotube reinforced epoxy composites were fabricated using shear mixing and sonication. The mechanical, viscoelastic, thermal, and electrical properties of the fabricated specimens were measured and evaluated. From the images and the results of the measurements of tensile strengths, the specimens having 0.6 wt% nanotube content showed better dispersion and higher strength than those of the other specimens. The Young’s moduli of the specimens increased as the nanotube filler... -

본 연구는 MWCNT로 보강된 SBR 나노복합재료를 컴파운딩법(compounding)으로 제조하여 산 처리된 MWCNT와 커플링제 상호간의 물리적 화학적 특성을 조사하였다. 황산과 질산으로 산화된 MWCNT는 FT-IR 분석 결과 -COOH로 기능화됨을 확인하였고, Raman 분석 결과 표면의 defect 존재와 disorder됨을 확인하였다. 또한, 제조된 SBR 복합재료의 가황 특성, 전기적 열적 특성 및 기계적 특성을 비교 평가하였다. 그 결과 산 처리된 MWCNT와 커플링제와의 상호 결합력으로 인해 기계적 물성은 상대적으로 증가하였으나, 전기적 열적 특성은... -

Characterization and influence of shear flow on the surface resistivity and mixing condition on the dispersion quality of multi-walled carbon nanotube/polycarbonate nanocomposites
Young Sil Lee, Kwan Han Yoon 한국탄소학회 Carbon Letters 7 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.2 3 86-92 (7 pages)
Multi-walled carbon nanotube (MWCNT)/polycarbonate (PC) nanocomposite was prepared by direct melt mixing to investigate the effect of the shear rate on the surface resistivity of the nanocomposites. In this study, an experiment was carried out to observe the shear induced orientation of the MWCNT in the polymer matrix using a very simple melt flow indexer with various loads. The compression-molded, should be eliminated. MWCNT/PC nanocomposite sample exhibited lower percolation thresholds (at 0.8... -

물에 분산되어 있는 multi-walled carbon nanotube (MWCNT)를 혼합시켜 전도성 코팅 용액을 제조한 후, 이것을 polycarbonate 기재 위에 도포하여 코팅 막을 형성하였다. ATWPUD와 MWCNT를 혼합하여 얻어진 코팅 막의 표면저항 값은 $10^{7.6}{sim}10^{7.7}{Omega}/cm^2$로 순수한 waterborne polyurethane dispersion (WPUD)과 MWCNT의 혼합물로부터 제조된 코팅 막의 $10^{10.9}{Omega}/cm^2$ 보다 우수한 전기전도도를 나타내었다. 또한 ATWPUD에 첨가되는 MWCNT의 양이 증가될수록 코팅 막의 전기전도도는 증가하였지만 연필경도 및... -
