Polymer nanocomposite reinforced with selectively synthesized coiled carbon nanofibers
Coiled carbon nanofiber were selectively synthesized over Inconel metal as substrate. Effect of different heating rates and substrate surface roughness on morphology of coiled carbon nanofibers was studied using various characterization techniques. After analysis of carbon growth, best heating rate for homogenous coiled growth was identified as 5 degrees C min(-1) with surface roughness of 1.7 mu m for Inconel. The coiled carbon nanofibers were used as filler materials with different wt. % in polyurethane for fabrication of nanocomposite. Properties of nanocomposites and nanofibers were studied using FESEM and XRD. Mechanical properties were also investigated by nano indentation, wear and tensile testing. There was 114% and 48% increase in elastic modulus and hardness respectively. With increase in wt. % of carbon nanofibers there was also decrease in wear and increase in tensile strength of polymer nanocomposite.
