在物理实验教学中需要导电纸，但要买到导电纸较困难，且价格又高，我们经研究，摸索出十分有效的制作导电纸的方法。制作过程将碳素墨水摇匀（上海吴经炭黑厂生产的碳素墨水好用），用排笔蘸上碳素墨水在纸上（市场上出售的复印纸）象刷油漆一样排刷，要求排笔一次要蘸饱墨水 Conductive paper is needed in physics experiment teaching, but it is difficult to buy conductive paper, and the price is high. We have studied and found a very effective method of producing conductive paper. During the production process, the carbon ink is shaken (carbon ink produced by the Shanghai Wujing Carbon Black Plant is easy to use), and the brush is brushed with carbon ink on a paper (copy paper sold on the market). Ask the pen to fill the ink once
