炭化水素鎖固定化処理綿布の表面形状と特性. (Japanese)

Surface Conngurations and Characteristics of Hydrocarbon Chain-immoDilized Cotton Fabric. (English)

In order to clarify surface configurations and characteristics of hydrocarbon chain-immobilized cotton fabric, the surface configurations of the immobilized cotton single nber were observed using a scanning electron microscope (SEM) and an amplitude modulation atomic force microscope (AMAFM). Changes in characteristics of cotton fabric and its fiber were measured on the phase mode and force curve of AM-AFM, and the coefficient of friction (MIU) and the mean deviation of MIU (MMD) of the friction tester (KES-SE). We obtain the following results-l)The resulted AFM image of the hydrocarbon chains immobilized fibers shows that a whole of single cotton fiber surface was covered with the hydrocarbon chains.2) From the phase ana adsorption images, it was found that the surface of the hydrocarbon chain-immobilized cotton fiber is a surface where the visco-elasticity and the adhesion force are largely fluctuated as compared with that of the untreated fiber. In addition, it was suggested that the fluctuation of adhesion force is related to the state of water caused by distribution and aggregation state of immobilized hydrocarbon chains. 3) MIU and MMD of the hydrocarbon chains immobilized fabric obtained by KES attaching silicon contactor are lower than that of untreated fabric.
