Abstract:

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.
