High Aspect Ratio Polymeric Nanoneedle Arrays [PDF]
Macromolecular Materials and Engineering, 2021 AbstractHigh aspect ratio (HAR) nanoneedle arrays can be used to tune the intrinsic properties of substrates such as their wettability and reflectivity. Here, a simple and scalable fabrication method for producing dense arrays of freestanding polyethylene glycol (PEG) nanoneedles with sub 50 nm tips and surface coverage up to 83 needles per µm2 is ...
