Research Statement
Polymer rheology which is the science for the flow and deformation of polymeric materials, is the main research field of my Ph. D. thesis. A nonlinear thermoviscoelastic constitutive equation derived from the modified rational thermodynamics framework was examined to assess its predictive capabilities in describing various nonlinear mechanical properties in the glass transition region for a glassy polymer, poly(vinyl acetate). Recently, my research interest has changed to the area of utilization of organic clays ; natural soils were treated with the ammonium ions having the long hydrocarbon chains, thus changing their property from hydrophilic to organophilic nature. These organically modified clays (i.e., organoclays) can be used for the removal of organic contaminants from the aqueous solution mainly by absorbing harmful, organic contaminants to the cores of pseudoorganic medium formed by the agglomeration of the long hydrocarbon chains of the exchanged ammonium ions present in the galleries of the clay. Furthermore, analysis of adsorption phenomenon in the adsorber is another research area I used to be involved in.
