Multi-dimensional characterizations of washing durable ZnO/phosphazene-siloxane coated fabrics via ToF-SIMS and XPS

open access: yesPolymer Testing, 2022
The poor washing durability of nylon fabric coating hinders their applications. Here, by spray coating zinc oxide (ZnO) and APESP siloxane on the surface of nylon 6, we find that the washing durability of the coated fabric could be enhanced dramatically.
