Synthesis, Characterisation And Water Permeability Of Mwnt Buckypapers
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 10
Abstract
Significant work has been conducted to examine the synthesis and characterisation of MWNT buckypapers. Optimisation of the sonication time, electron microscopic investigation, contact angle analysis, electrical properties measurements, mechanical properties testing and surface area analysis were studied and compared to those of corresponding buckypaper membranes containing the same surfactant Triton X-100. Analysis of scanning electron microscopic images of the surfaces of MWNT/Triton X-100 buckypapers revealed that the diameter of their surface pores (65.6 ± 2 nm) was marginally smaller than that of the corresponding materials prepared using MWNTs (80 ± 2 nm). In contrast, the average internal pore diameter of MWNT buckypapers (27.7 ± 2 nm) was found to be slightly higher than that of their MWNT counterparts (24 ± 1 nm), after analysis of binding isotherms derived from nitrogen adsorption/desorption measurements performed on the materials. The average electrical conductivity of MWNT/Triton-X buckypapers reported here (~56 S/cm) was roughly double the average conductivity of MWNT/Triton-X buckypapers mentioned in a previous study (~24 S/cm). Mechanical property measurements in this research displayed significant variation from those obtained from other MWNT buckypapers prepared under the same conditions. The tensile strength, Young’s modulus and ductility of the MWNT/Triton X-100 buckypaper prepared in this study were 3.4 ± 0.8 MPa, 0.4 ± 0.2 GPa and 2.4 ± 0.2% respectively.
