ABSTRACT A mulberry paper-based electromagnetic interference shielding material with screen-printing process was realized for high shielding effect and mechanical strength. With various film thickness of silver flakes achieved by controlling squeeze depth in the screen printer, the performance of the material was systematically investigated. By adaption of silver flakes on mulberry paper, the shielding effect of the screen-printed electromagnetic interference shielding material revealed over 70 decibels, which is the highest value of shielding effect for X-band. Moreover, after rupture test, 63% higher mechanical strength of 3.26 Mpa on the printed sample was observed compared to commercially available copy paper. As far as we know, this report is the first one related to the printed mulberry paper for electromagnetic interference shielding materials that require high mechanical strength with high shielding effect.

电磁干扰（EMI）屏蔽材料在桑纸上的丝网印刷工艺

摘要 利用丝网印刷工艺实现了一种具有高屏蔽效果和机械强度的桑椹纸基电磁干扰屏蔽材料。通过控制丝网印刷机中的挤压深度，获得不同膜厚的银片，系统地研究了材料的性能。银片在桑纸上的适应，丝网印刷的电磁干扰屏蔽材料的屏蔽效果达到70分贝以上，是X波段屏蔽效果的最高值。此外，在断裂试验后，与市售复印纸相比，在印刷样品上观察到 3.26 Mpa 的机械强度高 63%。据我们所知，
