ABSTRACT—In search of alternatives for the professional conservator to use in the struggle against fungi that deteriorate paper documents, we decided to research chitosan, considering its antimolding and strengthening properties. This, the first of two articles on the topic, addresses physical results. Samples of Whatman no. 1 filter paper were coated with three chitosan salts—chitosan acetate (AQ), chitosan butyrate (BQ), and chitosan propionate (PQ)—and three cellulose ethers—sodium carboxymethylcellulose (CMC), methylcellulose (MC), and hydroxypropylmethylcellulose (HPMC). After evaluating their physical properties of folding endurance, zero-span tensile strength, brightness, and pH, both before and after sterilization with ethylene oxide (EtO), we determined that both types of products increased the zero-span strength and folding endurance of the paper.
