Abstract

To understand the effects of enzyme pretreatments on the dynamic wettability，changes in dynamic wettability of a poplar surface treated with an enzyme were studied using the dynamic wettability model of a wood surface. Also，effects of enzyme concentration and enzyme pretreatment time on dynamic wettability of a poplar surface were discussed. Results showed that enzyme pretreatments improved the dynamic wettability of a poplar surface with K value increments on the treated poplar surfaces of 11.5% for distilled water，7.3% for glycerol，and 4.1% for methylene iodide. In addition，the dynamic wettability of the poplar surface increased as the dose of the enzyme increased，and for a droplet on the poplar surface，a longer treatment time obtained a higher dynamic wettability.［Ch，2 fig. 3 tab. 8 ref.］
