Summary
The researchers in this experiment were able to tune the shape of polymer nanofibrils using a very accessible and easy method. First they produced a polyurethane acrylate (PUA) nanofibril structure. Then, by bombarding the polymer with electrons at a shallow angle, the nanofibril structure begane bending over forming small hooks. The researchers forsee applications for adhesion as the stuctures resemble gecko setae, or 'nanovelcro'.
