Abstract
Semiconductor nanoparticle-modified NBR glove surfaces were treated with long chain fluoroacrylate copolymer to self-assemble fluoroacrylate copolymer molecules through their COOH functional groups, chemisorbed onto activated carbon nanoparticles surfaces, via cationic sites, on the surfaces which lack valency satisfaction. These chemisorptions of long-chain fluoroacrylate copolymer molecules on activated carbon nanoparticle surfaces leading to a full coverage of the particle surfaces with fluoroacrylate copolymer molecules a few Angstrom distance from the nanoparticle surface, thus introducing super-hydrophobic properties to the glove materials. The glove surfaces modified by semiconductor nanoparticles, activated carbon nanoparticles and fluoroacrylate copolymer molecules have contact angles greater than 170° and roll-off angles less than 2° thus providing excellent super-amphiphobic properties introduced to glove materials through our novel invention.

Background Art
Field of the Invention
The present invention is directed to Super-Amphiopobic property of the Poly(Nitryle- Butadiene)rubber glove.
Summary of Invention
Technical Problem
Biomimetic surfaces and materials received great attention of scientists and engineers due to their unusual properties. Biologically inspired design,derivation from nature is referred to as "biomimetics" Biological nanostructure have been observed on many kinds of surfaces such as rice leaves, butterfly wings,lotus leaves mosquito eyes, cicada wings, red rose petals, gecko feet, desert beetle, spider silks, and fish scales which contain excellent hydrophobicity or super- hydrophobicity . Such natural structures represent new insights into the design of artificial super- hydrophobic structures. A super-hydrophobic surface is a surface on which a drop of water forms an almost perfect sphere. Very slight tilting is sufficient to cause the water drop to roll off. However those properties are called high water contact angle and low sliding angle, the ability of a surface to bounce off water droplets contain the third property of a super-hydrophobic surface that is important for both biological and technical applications.
Solutions to Problem
Recently, a research work has been focused towards the preparation and theoretical modeling of super-hydrophobic surfaces as observed by the large number of publications and various approaches. Many efforts to create super-hydrophobic surfaces have been put forward. Many of the fabrication techniques are simple, inexpensivehowever; some of them included multistep procedures and harsh conditions, or required specialized reagents.The various methods for the preparation of biomimetic super-hydrophobic surfaces since last two decades have been reported, such as phase separation , electrochemical deposition , template method, Emulsion , plasma method , crystallization control , chemical vapor deposition , wet chemical reaction , sol-gel processing , lithography, electrospinning , solution immersionand so on. Besides water repellency, other properties such as transparency, colour change, anisotropy, reversibility,
flexibility, electrowetting, and breathability have also been incorporated into biomimetic super- hydrophobic surfaces. Although there are many exciting challenges facing this field, there are a number of opportunities in design, synthesis, and engineering of super-hydrophobic surfaces and
Advantageous Effect of Invention
These surfaces are of special important, because properties such as anti -microbial, mud resistance, and self-cleaning are expected. These properties are attractive for many industrial and biological applications such as anti-biofouling paints for boats, antis-ticking of snow for antennas and windows, self-cleaning windshields for automobiles, microfluidics, lab on chip devices, metal refining, stain resistant textiles, anti-soiling architectural coatings, and etc..
nature serves as a merchant of endless inspirations. Since last decade, many significant review articles have been published describing the different synthesis strategies to fabricate artificial super-hydrophobic surfaces.
Industrial applicability
This review will focus on the most recent developments (the last four years) in the super- hydrophobic surface research. The major part of this review is organized in four sections. The first section gives a brief introduction about the super-hydrophobic surfaces. In the second section, we review the theoretical basis relevant to the wetting of a solid surface by a liquid. The third section provides a comprehensive overview on the approaches for the preparation of super- hydrophobic surfaces, with particular focus on the fabrication methodology, materials, micro- nanostructures and potential industrial applications. Finally in the fourth section, we will provide our personal prospects and research directions about the construction of super-hydrophobic surfaces. Due to the space limitation, we cannot review all the significant and interesting work in the active super-hydrophobic field.
