H 3 PO 4 -activated poly(vinyl alcohol) coated fiberglass mats (PAPCF) were prepared in air at temperatures below 400 °C. The surface chemistry and pore structure of PAPCF were characterized by using N 2 adsorption at 77 K, XPS, DRIFTS, TGA, NaOH uptake and Ag + adsorption. PAPCF prepared at 300 °C yields a high BET surface area (up to 1745 m 2 /g of coating)...
Fibrous porous materials (FPMs) have been prepared by coating a glass fiber with an aqueous solution of poly(vinyl alcohol) (PVA) and H 3 PO 4 , followed by stabilization and heat treatment in air. The H 3 PO 4 was then removed by washing with deionised water and NaOH. The results show that H 3 PO 4 acts as a dehydration agent to promote pyrolytic and...
Fibrous porous materials (FPMs) have been prepared by coating a glass fiber with a solution of polymer and ZnCl 2 , followed by stabilization in air and heat treatment in N 2 . The ZnCl 2 was then removed by washing with D.I. water and HCl. Four kinds of polymers, a phenolic resin, polyacrylonitrile, poly(vinyl alcohol) and cellulose, were used to prepare solutions with ZnCl...
