摘要：plasma surtace modification (Argon: Hydrogen=0.6:0.4) of basalt fibers was mvestigated and the element contents of basalt and wood fibers were determined by X-ray energy dispersion spectroscope (EDS). configuration of basalt fibers was described by means of confocal Laser Raman microRaman spectrometer and Fourier transform infrared spectroscopy. And the morphology of fiber surface was studied with scanning electron microscope (SEM). The modified samples were characterized by X-ray photoelectron spectra (XPS). The results showed that the roughness of basalt fibers was increased with the increase of exposure time of plasma. At the same time the wettability and surface characteristics such as active groups of NH2, OH were improved as well. Basalt fibers were of good chemical stability, better mechanism intension and thermo-stability etc. They mainly consist of [SiO4]^4-, [Si2O6]^4-,[Si2O5]^2-. Further experiments demostrated that they were degraded into edaphic matrix after use. Therefore, they were environmentally friendly.
