By
treating microfiber cloths with SiO2 (Silica) nanoparticles in solution
we can "trap" a concentration of nanoparticles inside the structure of
each microfiber which is then replicated throughout the superstructure
of the cloth.
This allows us to create, among other things,
superhydrophobicity ("water-fearing") and oleophobicity ("oil fearing")
cloths, often displayed as the so-called "Lotus Effect" -i.e. suspending
a condensed droplet on the surface of the material.
Owing to
their fine, compact structure, microfibre textiles offer excellent
filtration effects for air filtration. Hence, although we have
hydrophobicity and oleophobicity, air molecules can still pass through
the cloth unencumbered.
The trapped silica nanoparticles within
the microfiber cloth can then be used to buffer conventional silica
glass or polymer plastic surfaces to remove fine dirt and create a high
optical transparency without creating erosion.
Moreover, by
buffering with the silica nanoparticle-saturated cloth we can in-effect
deposit a fine layer of silica nanoparticles on top of lightweight
polymer plastic optics.
this can in principle give otherwise
ordinary polymer optics the effect of having a thin layer of what is
effectively nanoparticulate glass which can reduce fogging and increase
durability with polymer optics which fog and corrode much more easily
than glass.
This can give us, in principle, a new way to easily
optimize polymer-based optics, which are relatively cheap and
lightweight, to the best of our abilities in applications where weight
and expense of conventional glass optics can be a problem for our goals.
