Nano Porous Carbon Film (NCS)
Product Detail
Nano porous carbon scaffold film (NCS) is a new type of carbon material. The basic components are carbon 91-95%, oxygen 4-8% and hydrogen 1%. If necessary, the carbon content can be further increased to 99%. Hydrogen and oxygen exist on the surface of the pore wall in the form of hydroxyl groups, and about 50% of the surface carbon atoms are connected with hydroxyl groups.
The advantages of NCS nano porous carbon membrane are as follows:
(1) Good conductivity
The carbon content in NCS is between 91-95%, which can be further increased to 99% if necessary, and has excellent conductivity (2-10 s / cm).
(2) Orderly internal structure
The internal structure of NCS is a three-dimensional through pore structure. The size and orientation of pores are very orderly, which is conducive to the diffusion of reactants and products.
(3) Strong controllability
The pore size of NCS is adjustable, which can be accurately regulated in the range of 10-1000 nm. The pore size of connecting holes between holes can also be regulated in a certain range, and micron pore structure can be introduced into NCS. The thickness of NCS can be adjusted in the range of 10-100 µ M. Chemical groups can also be modified inside NCS channels to realize the regulation of hydrophilicity and hydrophobicity.
(4) Excellent processing performance
NCS has certain mechanical strength and toughness, and is easy to process and shape without adding binder.
