Paper and cellulose-based materials lose strength and structural integrity when exposed to moisture due to the interaction of water with the material's hydrogen-bonding network.

The analysis

The retrieved literature consistently supports the widely established scientific consensus that unmodified cellulosic paper and fibers lose mechanical strength and become fragile when wet due to water disrupting internal hydrogen bonds and interacting strongly with hydroxyl groups.
