芬兰赫尔辛基大学的高分子研究人员通过高分子化学实验研究发现,用聚合物复合PEI包覆的铜粒子可以用于给纸张提供高导电表面。导电纸张需要一种比贵金属更为便宜的替代品,比如铜。聚合物是大分子化合物,性能会随温度发生
Macromolecular researchers at the University of Helsinki in Finland found through polymer chemistry experiments that copper particles coated with polymer-bound PEI can be used to provide paper with highly conductive surfaces. Conductive paper requires a cheaper alternative to a precious metal, such as copper. Polymers are macromolecular compounds that behave with temperature
