    摘要: A method for making a fine electrically conductive grid embedded in a polymer substrate. The method includes the steps of providing a polymer substrate, forming a pattern of grooves in the substrate, filling the grooves with electrically conductive powder, and then applying heat and/or pressure to the substrate. The application of heat and/or pressure to the substrate causes the grooves to collapse inward against the conductive powder. Collapsing the grooves compacts the conductive powder within the groove, thereby establishing a continuously conductive grid line or circuit. The narrow grid lines that result allow more light to transmit through the substrate. The method allows grid lines to be made with higher aspect ratios (ratio of line depth to line width) than is possible by previous methods.
