<p>A wallboard (10, 20, 30) comprising a gypsum layer (12, 22, 32) and a cellulose-based layer (14, 24, 34) comprising zinc oxide covering at least a portion of a surface of the gypsum layer (12, 22, 32) is disclosed. The zinc oxide can be impregnated into the cellulose-based layer (14, 34), or coated on a surface of the cellulose-based layer (14, 34). The zinc oxide can also be incorporated into the gypsum layer (22, 32). The zinc oxide can have a specific surface of from 2 m<SUP>2</SUP>/gram to 100 m<SUP>2</SUP>/gram. A method of making gypsum wallboard (10, 20, 30) is also disclosed.</p> |
