Studying the Possibility of Extending the Lifespan of Paper Documents and Archives Using the Polymer Coating Method.

Paper is a widely used material that is affected by environmental stresses and makes paper prone to damage. The paper is characterized by the absorption of water and moisture due to porosity, We have overcome this problem by employing polymer materials as water-resistant coatings acting as a barrier to protecting the paper, Polymer paper coating forms a clear membrane on the fiber forming a bridge of monomers on the surface of the paper. Two polymer coatings were used as a treatment, namely Polystyrene and sealer (alkyd resin). The results showed the possibility of enhancing the durability of the paper and preserving it from damage and deterioration. The treatment gave a decrease in moisture content, response to abrasion and scratching while increased folding tolerability, the burst strength, tear resistance, hardness compared to untreated paper and the paper porosity important indicator to overcome. The degree of brightness, the degree of color and visible light and ultraviolet radiation [UV] effect of the specimens were studied in detail. [ABSTRACT FROM AUTHOR]
