A solvent-free electroconductive composition may be used to make electroconductive lines on a surface of a substrate or electroconductive plugs within via holes of a substrate. The solvent-free electroconductive composition is generally made of about 40 to about 95 wt % of a conductive component, about 4 to about 30 wt % of a polymer or oligomer comprising a reactive functional group, up to about 20 wt % of a monomeric diluent comprising a reactive functional group, and up to about 3 wt % of a curing agent. In some instances, the solvent-free electroconductive composition further includes up to about 3 wt % of a lubricating compound. Substrates made using solvent-free electroconductive compositions may be used in printed circuit boards, integrated circuits, solar cells, capacitors, resistors, thermistors, varistors, resonators, transducers, inductors, and multilayer ferrite beads.
无溶剂导电组合物可用于在基材表面制作导电线或在基材通孔内制作导电塞。无溶剂导电组合物一般由约 40 至约 95 wt % 的导电成分、约 4 至约 30 wt % 含有活性官能团的聚合物或低聚物、最多约 20 wt % 含有活性官能团的单体稀释剂和最多约 3 wt % 的固化剂组成。在某些情况下,无溶剂导电组合物还包括最多约 3 wt % 的润滑化合物。使用无溶剂导电组合物制成的基板可用于印刷电路板、集成电路、太阳能电池、电容器、电阻器、热敏电阻器、压敏电阻器、谐振器、传感器、电感器和多层铁氧体磁珠。
