How strong is the adsorption capacity of activated carbon fiber felt? After high temperature activation of carbon fiber, the surface of the fiber is full of micropores (that is, the position occupied by hydrogen and oxygen atoms before volatilization). The pore size is one hundred thousandth of a human hair. The inner surface of the micropores is spread out, and the spread area of 1g of activated carbon fiber felt is as high as 1600 square meters. This is because these micropores play the role of odor absorption. It can be known from physics that there is gravitational force on the surface of an object. The larger the surface, the greater the adsorption force. It is through this van der Waals force that the activated carbon fiber adsorbs surrounding molecules and is firmly in the micropores.

The comparison results of the adsorption function are as follows:

Powder activated carbon (Pac)<Activated carbon rod (CTO)<Granular activated carbon (GAC)<Carbon fiber (ACF)
