导电功能木质复合板材的渗滤阈值

PERCOLATION THRESHOLD OF ELECTRICALLY CONDUCTIVE FUNCTION IN WOOD-BASED COMPOSITE PANELS

通过导电单元掺杂粘合单元并叠层复合木质单元研究了导电功能木质复合板材的渗滤阈值。结果表明 ,形成渗滤效应时的阈值为 8%～ 1 4 % ,对应的导电单元施加量和填充量分别约为 1 4 %～ 2 5%和 1 2 %～ 2 0 % ;形成渗滤效应之后 ,导电功能的均匀性较好。此外 ,相关机理和量化关系还有待于深入研究。

The percolation threshold of electrically conductive function was studied by mixing adhesive elements with conductive elements and then laminating with wood elements together to form wood\|based composite panels.The results showed that the threshold values were about 8%～14%,and the spreading content and filling content were correspondingly about 14%～25% and 12%～20%,respectively.The uniformity of conductive function was better once the percolation phenomena occurred.Additionally,some mechanism and numerical relationship should be further researched.
