Preparation and Properties of Kevlar or Polysulfonamide Pulp Reinforced Activated Carbon Fiber Paper

Abstract:

In this paper, Kevlar or Polysulfonamide (PSA) pulp were used to replace plant fiber pulp partially or completely and by adjusting their ratios and a variety of Kevlar or PSA pulp reinforced activated carbon fiber paper (ACFP) were prepared via wet-laid paper making technology. The influences of addition of Kevlar or PSA pulp on the permeability, mechanical property, filtration performance, adsorption property of ACFP were discussed by maintaining the addition content of activated carbon fiber unchanged. Results showed that with the addition content of Kevlar or PSA pulp increased, the permeability and filtration performance of ACFP decreased obviously, while the bursting strength and the static CCl₄ adsorption performances were firstly increased and then decreased. Generally, the permeability and filtration performance of Kevlar pulp reinforced ACFP were slightly worse than that of PSA pulp reinforced ACFP, while the bursting strength as well as the static CCl₄ adsorption properties of Kevlar pulp reinforced ACFP were better than that of PSA pulp reinforced ACFP.
