Superhydrophobic film fabricated by controlled microphase separation of PEO–PLA mixture and its transparence property

Preparation and characterization of poly(lactic acid)/poly(ethylene oxide) blend film: effects of poly(ethylene oxide) and poly(ethylene glycol) on the properties

“…have investigated the miscibility, mechanical properties and biodegradation of melt‐extruded PLA/PEO and PLA/PEG blends and found that the tensile strength and elongation at break of PLA/PEO blown films increase when the PEO content is 15 wt% . Micro‐phase separation of solvent‐cast PLA/PEO, during superhydrophobic transparent film fabrication, was shown by Pi et al . Oliviera et al .…”

Facile Preparation of a Fluorine‐Free, Robust, Superhydrophobic Coating through Dip Coating Combined with Non‐Solvent Induced Phase Separation (Dip‐Coating‐NIPS) Method

“…It was revealed by Jiang et al [ 14 ] that in addition to micron‐scale papillae and epicuticular wax, the nanoscale roughness on the surface of a lotus leaf plays a crucial role in superhydrophobicity. Hence, myriads of methodologies have been developed to construct superhydrophobic surfaces based on the combination of micro‐/nanoscale two‐tier structure and low‐surface‐energy material, including sol–gel processing, [ 5,15 ] electrospinning, [ 16 ] lithography, [ 17,18 ] molding, [ 19,20 ] layer‐by‐layer assembly, [ 21,22 ] phase separation, [ 11,23–26 ] and chemical etching. [ 27 ] Among all these approaches, phase separation is a straightforward and low‐cost, but rather effective way to obtain superhydrophobic surfaces, which was utilized to prepare a self‐cleaning polypropylene film early in 2003 by Erbil et al [ 28 ]…”

“…[ 31 ] Nanoparticles, which can act as nucleating agents and alter the phase separation pathway, are commonly used in NIPS to create a patterned surface and increase roughness. [ 25,32 ] Meng et al [ 33 ] reported a superhydrophobic and water‐vapor permeable coating using poly(styrene‐ block ‐butadiene‐ block ‐styrene) and hydrophobic SiO 2 nanoparticles through the spray‐coating technique in combination with non‐solvent vapor induced phase separation; the material could be applied to prepare waterproof but breathable textile. Seyfi et al [ 34 ] proposed a method combining nanoparticles and a non‐solvent to fabricate superhydrophobic polystyrene coatings with self‐cleaning functionality; the incorporation of nanoparticles was found to improve the adhesion strength and mechanical stability of the obtained coatings, compared with those prepared using a non‐solvent only.…”

Durable bonding of silica nanoparticles to polymers by photoradiation for control of surface properties

“…The first is based on top–down fabrication methods that include plasma etching and soft lithography . The second is based on bottom–up texturing or self‐assembly methods including sol–gel processes, electrodeposition, microphase separation, templating, controlled design, and nanoparticle (NP) assembly . The third approach is based on replicating methodologies including biologically inspired design, also referred as biomimetic.…”
