Industrial applications of

nanotechnology

  urfaces and coatings-

The most prominent application of

nanotechnology in the household

is self-cleaning or "easy-to-clean"

surfaces on ceramics or glasses.

Nano ceramic particles have

improved the smoothness andheat resistance of common

household equipment such as the

flat iron.

Textiles:-

The use of engineered nanofibers

already makes clothes water- and

stain-repellent or wrinkle-free.

Textiles with a nanotechnological

finish can be washed less

frequently and at lower

temperatures.

Nanotechnology has been used to

integrate tiny carbon particles

membrane and guarantee full-

surface protection from

electrostatic charges for the

wearer.

Military

y using nanotechnology! the

military would be able tocreate sensor systems that

could detect biological agents.

 Nanoparticles can be inected

into the material on soldiers#

uniforms to not only make the

material more durable! butalso to protect soldiers from

many different dangers such

as high temperatures! impacts

and chemicals.
