摘要：
The dispersive component of the surface free energy γds of glass fibers and their acid-base interaction can be evaluated by the measurement of specific retention volumes of several kinds of probe molecules by use of an inverse gas chromatography. The effect of the treatment of glass fibers with silane-coupling agents was also evaluated. The specific retention volumes of n-alkanes changed linearly with their C number or vapor pressure. Those of polar molecules varied with their donor number (DN) or acceptor number (AN). The γsd values and electron-accepting or donating abilities depended upon the kind of functional groups contained in the coupling agents. © 1990 Steinkopff.
