The Covid-19 coronavirus, SARS-CoV-2, is inactivated much faster on paper (3 h) than on plastic (7 d). By classifying materials according to virus stability on their surface, the following list is obtained (from long to short stability): polypropylene (mask), plastic, glass, stainless steel, pig skin, cardboard, banknote, cotton, wood, paper, tissue, copper. These observations and other studies suggest that SARS-CoV-2 may be inactivated by dryness on water absorbent porous materials but sheltered by long-persisting micro-droplets of water on waterproof surfaces. If such physical phenomenons were confirmed by direct evidence, the persistence of the virus on any surface could be predicted, and new porous objects could be designed to eliminate the virus faster.
新冠病毒（Covid-19 coronavirus，SARS-CoV-2）在纸张（3 小时）上的失活速度比在塑料（7 天）上快得多。通过根据其表面上病毒的稳定性对材料进行分类，得到以下列表（从稳定性长到短）：聚丙烯（口罩）、塑料、玻璃、不锈钢、猪皮、纸板、钞票、棉花、木材、纸张、纸巾、铜。这些观察结果和其他研究表明，SARS-CoV-2 可能会在吸水性多孔材料上因干燥而失活，但在防水表面上持续存在的小水滴的庇护下得以存活。如果这些物理现象被直接证据所证实，那么任何表面上病毒的持久性都可以被预测，并且可以设计新的多孔物体来更快地消除病毒。
