A STUDY ON THE BIOSTABILITY OF PARYLENE-COATED PAPER

The article deals with the stability of paper coated with poly-para-xy lylene (parylene) as compared with the laminate paper-polyethylene tha t is widely used in archive paper conservation. The intensity of paper deterioration by fungi was estimated by loss in mas and by the result s of electronic microscopy. The investigations showed that mould growt h on paper coated with parylene (and polyethylene as well) is the resu lt of fungi consuming the paper in parts with mechanical damage in the coating rather than the result of fungi consuming the synthetics.
