The effect of radio-frequency (rf) plasma and rf electromagnetic field treatment on some physical and chemical properties of a white typographical paper has been studied. Paper samples were processed in 5.28 MHz helium plasma of a capacitively coupled rf discharge at pressure 0.7 Torr as well as were exposed to rf magnetic field at atmospheric pressure under conditions of the prebreakdown mode operation of the rf discharge. Structural features of paper before and after the treatment have been investigated using several techniques: digital laser speckle technique, laser goniophotometric Stokes polarimeter and attenuated total reflectance (ATR) infrared spectroscopy. It was shown that the plasma treatment modifies the microstructure of paper tissue without visible change of its macrostructure. The changes of statistical distributions of speckle patterns has been observed for plasma treated paper as a result of increase of correlative dimensions of structural heterogeneity of modified paper. The most probable reason of this effect is porosity increase of the paper as well as cellulose fibrils splitting. It has been shown also from the measurements of the polarization characteristics of radiation reflected and scattered by paper surface, that the magnetic component of the rf electromagnetic field exposure resulted in the structural orderliness decrease of the tissue, values reduction of paper's bi-directional reflection and transmission distribution functions, change of the shape of indicatrix of reflected light power at the wave length of 632.8 nm. In the case of perpendicular orientation of magnetic force lines to the plane of a paper sheet the more essential decrease of anisotropy in a surface and volume layers of a paper is observed, than at their parallel orientation. A frequency shift in the ATR spectra (in the range of 1300 – 1500 cm-1) has been observed also as a result of the rf electromagnetic field exposure. It may be connected with orientation effects of cellulose macromolecules and change their conformational structure.
