Surface characterization of glass fiber by inverse gas chromatography

Abstract

The surface properties of glass fiber were quantificationally analyzed by inverse gas chromatography (IGC). Five n-alkanes (C₆, C₇, C₈, C₉, and C₁₀) were chosen as apolar probes to characterize the dispersive component of surface free energy. Trichloromethane (CHCl₃), acetone, and tetrahydrofuran (THF) were chosen as polar probes to detect the Lewis acid-base parameters. It is found that the dispersive components of free energy are 32.3, 30.5, 27.5, and 26.9 mJ/m² at 70, 80, 90, and 100 °C, respectively. The Lewis acidic number K _a of the glass fiber is 0.512 4, and the basic number K _b is 2.862. The results mean the glass fiber is a Lewis basic material.
