P2F aims to produce a medically certified antiviral nano mask. The masks will be electrospun. Existing masks are made from melt blown material. MB material is uncomfortable for long use, and more importantly drops in filtration efficiency, when moist.
Advantages of an Electrospun Nano mask (NM) over Melt Blown (MB) masks:
1. Better breathing comfort than MB masks: The NF filter has finer structure than MB, uniform morphology, and uniform pore diameter which allows the water vapor laden air to be passed through the filter more efficiently, with less resistance. (My guess is that more air tends to flow from gaps around the mask if the material is resistant to flow, of course “fit” is a big issue)
2. Dries faster after washing (I think the intention eventually is to produce a washable one, its what the govt hopes for)
3. More consistently effective as bacterial/viral filter than MB (filtration efficiency based on particle size vs pore size, rather than static charge) (50-100nm pore size, air particle size is 4nm, viral particle size 80-160nm, latter bigger when incorporated within saliva)
AND 2 points which are advantages of having an antiviral Nano mask:
4. Nano particles (Ag/TiO2/Zn/Cu) within the mask material, have for a long time now, been shown to demonstrate biocidal property: this could help reduce virus transmission via contact for ex
5. Disposal of USED masks is a key issue given current masks end up harbouring the virus, even if they filter them. Masks currently worn for long periods, can become virus collectors esp in health care setting. (humid air from breathing reduces filtration; creates the conditions needed for penetration of the virus/bacterium into the mask)
All in all, definite demand and market for a scientifically proven antiviral mask, indeed space for numerous such types of mask manufacturers given the scale of the demand.
The concept of masks to reduce respiratory viral/bacterial infections will remain beyond Covid. Indeed there is evidence of copper’s biocidal property against MRSA and other hospital acquired infections. The use of P2F nano tech to “treat” surfaces, other PPE such as aprons, gloves etc lies ahead. There are also filters in various situations as others have pointed out.
The main point that I m looking for, is whether they actually convert the myriad opportunities. They seem to be moving quickly. Nsitu trademark for their brand of agri products/fertilisers for example, got registered as a trade mark in March 2020. They own patents on the manufacture process of nano particles (I believe its unique) and another patent on the incorporation of the nano particles into an organic compound (to apply as fertiliser to crops). Now they are moving towards a further patent on the nano filter material. It portends a company that is focussed on opportunities and keen to commercialise. A welcome change from the geocurve-gyrometric lethargy. IMHO only. DYOR.
