Investigation of polymer nanocomposites reinforced with nanocarbon.

摘要

Polymer / nanocarbon composites have excellent mechanical and electrical properties. In this study polycaprolactum (nylon-6) reinforced with multiwalled carbon nanotubes (MWCNT's) and graphene is examined and compared to nylon-6 nanofiber. Polycaprolactum functionalized with nanocarbon is prepared and characterized using Scanning Electron Microscopy (SEM), Differential Scanning Calorimetry (DSC) and Thermo Gravimetric Analysis (TGA). Nylon-6 nanofibers are spun by electro spinning process. The fibers with a dimension of 400-500 nm are obtained and is revealed by SEM. Reinforcement of nanocarbon is done by dip coating process. Nanocarbon (MWCNT's and graphene) is suspended in deionized water mixed with surfactant TritonX-100 for uniform dispersion. The nylon-6 nanofiber material is then dipped in the nanocarbon (MWCNT's and graphene) solution and then dipped in deionized water to remove excess nanocarbon. Dip coating process is done by using MWCNT's solution; graphene solution and a mixture of both. The fibers are then dried at room temperature. The morphology, crystallinity and thermal stability of polymer/nanocarbon composite are analyzed by using SEM, DSC and TGA.
