Civil Engineering Nanocomposites Nano-composites Carbon Nanofibers Polylactic Acid PLA Green Polymers This thesis evaluates the effects of graphite based carbon nanofibers (CNF) when incorporated within a NatureWorks Ingeo 3001D Polylactide (PLA) matrix. A film casting method was conducted in which CNF was mixed via sonication with neat PLA at 1% wt., 3% wt., and 5% wt. doses in aims of enhancing nanomechanical behavior and conductivity. A melt compounding method via twin extrusion, was also performed to fabricate PLA/CNF samples at the same CNF wt. doses as employed by the film casting method. Nanocharacterization of samples were performed via Atomic Force Microscopy (AFM) and Scanning Electron Microscopy to evaluate nanomechanical properties and nano/micro structure of PLA/CNF samples. The PLA/1%wt. CNF sample mechanically performed better than the neat PLA, 3%, and 5% CNF samples for the film cast (69,996.94 ± 4,545.29 psi) and extruded (95,111.72 ± 30,388.96 psi) methods with respect to AFM nanoindentation. Macroscale tensile testing was performed effectively extruded samples in which the PLA/3%wt. CNF loading case (Young's Modulus = 295,594.18 psi) performed the best. Conductivity measurements were also completed to evaluate the potential for PLA/CNF based nanocomposites to be considered electrical sensors for civil engineering applications. The PLA/5%wt. CNF film cast sample was found to possess the most favorable electrical resistance (859.45 O), while all other samples were deemed not conductive due to improper dispersion of CNF particulates. 2014 English text Ohio University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ohiou1408697877 http://rave.ohiolink.edu/etdc/view?acc_num=ohiou1408697877 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
