Nanofibre coatings

Micro- or nanofibre coatings are applied to the nonwoven substrate surface to create special surface properties (e.g. filter/barrier).

Textile materials can be used in moist wound management as fibres themselves (advanced fibres such as alginate and chitosan fibres), or conventional/advanced fibres can be modified or coated with various substances such as honey or hydrogels to obtain special properties such as ultra-absorbency, drag release, etc. In general, textiles used in wound-dressing products come in all possible forms, including fibres, nanofibres, filaments, yarns, and woven/knitted/non-woven and composite materials. 

Zhao et al. [68] prepared UF membrane by coating CS on electrospun nanofibrous polyvinylidene difluoride scaffolds. Further, the membrane was cross-linked using GA and modified using terephthaloyl chloride. The resultant UF membrane has shown excellent water-protein liquid filtration. Lin et al. [69] used to couple CS/UF process for the removal of dissolved organic matter and arsenic. They concluded that CS has a weak affinity for arsenic but is a good adsorbent for dissolved organic matter. A maximum of 65% arsenic rejection was achieved by the combined interactions of humic compound, CS, and arsenic.

There are some commercially available electrospinning processes, such as the Nanospider electrospun nanofibres, which can provide thin coatings on traditional filtration substrates and enhance the filtration performance of these materials many fold. This technology can yield nanofibres with a narrow diameter distribution and distinct diameter size that can be used to optimise the filtration behaviour of the filter substrates for many applications, where particle retention efficiency is a critical requirement. These suhmicron fibres can significantly improve the air filtration efficiency of a variety of media and filters. The submicron fibres provide improved filter efficiency in the interception and inertial impaction regimes. ... 

Silver/polypyrrole/polyacrylonitrile composite nanofibrous mats were obtained by applying coating method. AgN03/PAN mats were prepared by electrospinning and the mats were placed into the boiling mixture of pyrrole and toluene. Then the pyrrole was oxidized by silver ions, leading to PPy and elemental Ag.
