How is a virus able to survive on some surfaces longer than others?

Obviously I’m wondering this because I’ve heard COVID-19 can survive on plastic much longer than paper, and on paper much longer than certain metals.

What about those surfaces is able to keep the virus alive longer than the others?

Viruses need wet environments to remain intact and functional. A material with a lot of nooks and crannies or an absorbent material can that hold water gives e viral particles a wet place to stay intact and infectious. A smooth surface dries out quickly and thus the virus deactivates that much more quickly.
