Fabrication of Poly Phosphoric Acid into Polyacrilonitrile Composite Nanofibers

Abstract

Poly phosphoric acid/ Polyacrilonitrile composite nanofibers (PPA/PAN composite nanofibers) has been fabricated by the electro-spinning of PAN solutions containing different amount of PPA. The prepared nanofibers have been characterized by the using of FT-IR, SEM and XRD techniques

Design and characterization of nano-silica-bonded 3-n-propyl-1-sulfonic acid imidazolium chloride {nano-SB-[PSIM]Cl} as a novel, heterogeneous and reusable catalyst for the condensation of arylaldehydes with β-naphthol and alkyl carbamates

“…For example, a-aminoalkyl-b-naphthol derivatives have bradycardiac and hypotensive properties [34,35]. One of the rational synthetic approaches toward a-carbamatoalkyl-b-naphthols is the catalyzed condensation of arylaldehydes with b-naphthol and alkyl carbamates [36][37][38][39][40][41][42][43][44][45][46][47][48][49][50].…”
