A polymer with a 2D molecular structure stacks into tightly packed layers — forming films of nanoscale thicknesses that are nearly impermeable to gases and moisture. Polymers are attractive barrier ...

Because it's nearly impermeable to gases, the polymer coating could be used to protect solar panels, machinery, infrastructure, and more. (Nanowerk News) MIT researchers have developed a lightweight ...

MIT researchers tested the gas permeability of their new polymer films by suspending them over microwells to form bubbles. Some bubbles from 2021 experiments are still inflated. This optical ...
