Mechanical Engineering Materials Science Coal Surface Modification Functionalization Coupling Agents Composites Esterification This study evaluated the functionalization of bituminous and sub-bituminous coals via acid and hydrogen peroxide routes to improve interfacial adhesion in coal-plastic composites. Three coals were studied, including Pittsburgh No. 8, Kittanning, and Powder River Basin. Boehm analysis and Fourier-transform infrared spectroscopy were used to study coal surface chemistry. Additionally, the interactions (esterification) between the coal’s hydroxyl functional groups and graft-maleic anhydride on four different coupling agents were studied. An investigation of the effect of coal filler content (0-60 wt.%) and coupling agent content (0-3 wt.%) on the tensile and flexure properties of the material was conducted. When the coupling agent was added, the greatest improvement in mechanical properties occurred at 60 wt.% coal content and 3 wt.% coupling agent (maleic anhydride grafted-polypropylene) content. 2020-06-01 English text Ohio University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ohiou1576755034712695 http://rave.ohiolink.edu/etdc/view?acc_num=ohiou1576755034712695 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
