Stabilization And Preservation Of Charred Documents Using Natural Polysaccharides And Their Decipherment

Abstract

Charred documents pose a significant challenge in forensic document examination, requiring specialized techniques for their stabilization and decipherment. Conventional methods for charred document examination commonly employ chemicals such as polyvinyl acetate (PVA) for their preservation; however, the use of PVA and similar chemicals presents several drawbacks, including limited availability, toxic effects, non-biodegradability, poor resistance to weather and moisture, and slow setting speed. These limitations highlight the need for alternative, more environment-friendly solutions that can effectively stabilize and preserve charred documents while facilitating their future examination and analysis. This thesis aimed to address this need by proposing a green and novel coating material synthesized from natural polysaccharides, providing a promisin newlineg alternative to polyvinyl acetate to stabilize and decipher charred documents. newline newline
