The conservation and protection of historic monuments or
culturally significant structures have recently attracted much attention from
material scientists. A few years ago, various synthetic polymers have been
widely used in the treatment
of construction materials of historical monuments for consolidation and
conservation of such structures. Using polymeric coatings for this area has
created serious challenges for the surface science and technology. Some of the challenges
are as follows.
Van Hees and Brocken evaluated the salt growth in brick
masonry specimens, coated with a water repellent, during a salt crystallization
test. They demonstrated that the behavior of different salts on development of
salt damages is completely different. However, it is demonstrated that the
adsorption of dusts suspensions and watersoluble air pollutants decreases with
increasing hydrophobicity of the surface of building materials.
The fluorine substitution of the hydrogen atoms present in a
macromolecular chain improves the heat resistance and chemical resistance,
delays or inhibits flame propagation, lowering the critical surface tension and
exalts the dielectric characteristics.Acrylic resins undergo deterioration face
conditions under UV
radiation and their climatic exposure causes degradation of their
structure. However, their physical characteristics and low price always
consider important research topics. In this research work, the focus was on the
development of films of PVDF and PMMA blends and their spectroscopic analysis
(FTIR and UV-visible spectroscopy).
