Transport characteristic of porous polymer particles studied by inverse gas chromatography (iGC) and tomography
Original language description
The goal of this study is to demonstrate the application of inverse gas chromatography (iGC) in the characterization of polymer particle morphology and the estimation of penetrant transport in porous polyolefine particles. Standard theories of iGC consider only diffusion and adsorption inside porous particles. In our case the theory of iGC has to be extended about the diffusion of penetrants taking place both in particle pores and in particle polymer phase. Moreover, our capability to perform iGC measurements at various pressures proved to be valuable, because the diffusivity is inversely proportional to pressure. The iGC technique is useful in the characterization of the interactions between mobile gas phase and stationary solid phase (i.e., porous polymer particles) placed in the column. We shall first introduce our experimental apparatus allowing the measurements in the long thermostated columns at temperature up to 120?C and pressure up to 12 bar. Column characteristics are evaluat
