Abstract

Hydrophobic archival envelopes based on two different types of Hanji papers were prepared by gas grafting treatment with palmitoyl chloride. Samples of Hanji and copy paper were placed in each archival envelope, and after moist heat treatment at 80℃ and 65% relative humidity, the mechanical and optical properties of the paper samples before and after aging were measured. Except for the Hanji sample stored in a hydrophobic envelope based on traditional Hanji paper prepared by adding a mucilage of hibiscus roots, the strengths of the Hanji and copy paper samples stored in hydrophobic envelopes were higher than those stored in hydrophilic envelopes. However, no differences in the optical properties of the Hanji and copy paper samples were observed with regard to the hydrophobic treatment of the archival envelope. Consequently, we conclude that the hydrophobic treatment of the Hanji based archival envelope does not produce a significant improvement in the conservation characteristics of paper materials. We speculate that this is due to the gas-grafting treatment with the fatty acid chloride providing the paper with barrier properties to liquid moisture rather than to gas.
