To put it simply, nanofibers are a super, super thin material that can be made from a super strong (and super thin) carbon material, and are generally good conductors of heat and electricity.
Nanofibers were first produced via electrospinning more than four centuries ago. [28] [29] Beginning with the development of the electrospinning method, English physicist William Gilbert (1544-1603) first documented the electrostatic attraction between liquids by preparing an experiment in which he observed a spherical water drop on a dry surface warp into a cone shape when it was held below ...
Polymeric nanofibers have been used in air filtration applications for more than seven decades. [49] [59] Because of poor bulk mechanical properties of thin nanowebs, they are laid over a filtration medium substrate. The small fiber diameters cause slip flows at fiber surfaces, causing an increase in the interception and inertial impaction ...
Another study shows the potential of polyaniline nanofibers as NO 2 gas sensors. [13] NO 2 gas acts as a strong oxidizing agent to the emeraldine form of polyaniline nanofibers, which causes resistance changes greater than three orders of magnitude at 100 ppm. Sensing targets can be expanded through adding materials to the polyaniline nanofibers.
Nanofibers are key to the story and outcome of '3 Body Problem,' Netflix's major new sci-fi series. ... super thin material that can be made from a super strong (and super thin) carbon material ...
A strong electric field is applied to the solution to charge the polymer strands. The solution is put into a syringe and aimed at an oppositely charged collector plate. When the force of attraction between the polymer nanofibers and the collector plate exceed the surface tension of the solution , the nanofibers are released from the solution ...
A strong electric field of the order of 103 V/cm is applied to the polymer solution droplets emerging from a cylindrical die. The electric charges, which are accumulated on the surface of the droplet, cause droplet deformation along the field direction, even though the surface tension counteracts droplet evolution.
