What's Happening?
Researchers led by Michael S. Strano and J. Scott Bunch have developed spin-coated 2D polyaramid nanofilms that exhibit molecular impermeability, akin to inorganic crystalline materials. These nanofilms, synthesized through polycondensation, feature nanoplatelets with diameters around 10 nm. The films, processed using trifluoracetic acid, demonstrate high chemical stability and mechanical robustness, comparable to graphene. Testing revealed that even the thinnest films (4 nm) maintained their integrity, with a gas permeability threshold significantly lower than existing liquid-crystalline polymers. This advancement in nanofilm technology could have wide-ranging applications in various industries.
