Abstract:
The aim of this research was the abatement of the microbial contamination on paper and paper consolidation by plasma treatment.
Plasma sterilization proved to be more efficient than three traditional
treatments. For plasma processes, two
gas mixtures, Ar/H2 and O2/H2, were
compared as a function of power and
time. Scanning electron microscopy
observations and Fourier transform
infrared spectroscopy by attenuated
total reflectance seemed to show that
the plasma treatment did not affect the
paper surface. X-ray photoelectron
spectroscopy detected very small
changes of the functional groups at the
surface of the paper sheets. Although
the two mixtures had the same
sterilization efficacy, the optical
emission spectroscopy, which measures
the ultraviolet, and the tensile strength,
measured before and after the
treatment, indicated that the O2/H2
mixture was to be preferred. The consolidation of paper using plasma
treatment was successfully carried out
with a silicon-like film.
