TLDR
In this article, the authors review the recent work on the deterministic (top-down) micro/nano structuring and stochastic (random) micro-nano texturing of polymeric materials for a variety of applications.Abstract:
We review our recent work on the deterministic (top down) micro/nano structuring and stochastic (random) micro/nano texturing of polymeric materials for a variety of applications. We create polymeric microfludics/microsystems using plasma processing as well as 'smart' polymer surfaces with controlled wetting and optical properties. First, fabrication of polymeric micro-nanosystems and microfluidics using standard photolithography followed by plasma etching is proposed as an alternative method for polymer microfabrication. Second, plasma induced polymer nanoroughening (nanotexturing) is proposed as an extremely attractive methodology to control the wetting properties of polymers and create superhydrophilic or hydrophobic or robust superhydrophobic polymer surfaces. These surfaces may in addition possess controlled optical properties, such as antireflectance combined with good transmittance. Third, ordered spontaneously formed structures are created on plasma processed polymers. Potential applications are discussed.read more

TL;DR: In this paper, the authors describe how plasma-wall interactions in etching plasmas lead to either random roughening/nanotexturing of polymeric and silicon surfaces, or formation of organized nanostructures on such surfaces.

Philip S. Brown,Bharat Bhushan +1 more
TL;DR: A facile method for creating re-entrant geometries desirable for superoleophobicity via entrapment of nanoparticles in polycarbonate surfaces is reported, which could prove useful in improving the anti-bacterial, mechanical, and liquid-repellent properties of plastic devices.

TL;DR: In this paper, the structural stability of the nanotexture against capillary and adhesion forces during successive wetting-drying cycles, and the thermodynamic stability (robustness) of these surfaces related to the maximum sustainable pressure of the Cassie-Baxter inhomogeneous wetting state were investigated.
