The interfacial adhesion of the composite materials was evaluated using the single fiber fragmentation technique. The results indicated an improvement in the interfacial shear strength with the addition of the short-MWCNTs treated with acid solutions and grafted onto the surface of the CF fiber using electrostatic attraction. -

MWCNTs/B-epoxy) were examined by employing dynamic mechanical analysis, critical stress intensity factor (KIC) tests, and impact strength tests. The electromagnetic interference shielding effectiveness (EMI-SE) of the composites was evaluated using reflection and absorption methods. Mechanical properties of MWCNTs/B-epoxy were enhanced with an increase in the MWCNT content, whereas they deteriorated when the MWCNT content was >5 parts per hundred resin (phr). This can likely be attributed to the... -

of carbons with adjacent shells separation of ~0.34 nm. Multiwalled carbon nanotubes were synthesized by arc-discharge technique. MWCNTs were formed at the cathode deposit along with other carbonaceous materials like amorphous carbon, graphite etc. However, to get the best advantage of carbon nanotubes in various advanced applications, these undesired carbonaceous materials to be removed which is... -

본 연구에서는 방사선에 의한 그래프트 중합을 이용하여 생체분자가 고정화된 다중벽탄소나노튜브 (MWCNT)를 제조하였다. 생체분자의 고정화를 위하여 MWCNT에 아크릴 산을 그래프트 중합하였다. 열중량분석과 라만 분석을 통하여 MWCNT에 폴리(아크릴 산)이 효과적으로 그래프트 중합되었음을 확인하였다. 폴리(아크릴 산)이 그래프트 된 MWCNT에 DNA와 단백질과 같은 생체분자들을 고정화하였다. X-선 광전자 분광법과 형광분석을 통하여 생체분자들이 성공적으로 MWCNT에 도입되었음이 확인되었다. -
