Abstract
Fluorene-containing poly(aryl ether nitrile) (FPAN) was prepared by a typically aromatic nucleophilic substitution polymerization. The chemical structure of FPAN was confirmed by FTIR and 1H NMR spectroscopy. Different morphologies of FPAN fibers could obtain through electrospinning. The light-emission properties of polymer in solution, casting film and fibrous membrane were examined by spectrofluorometry. This polymer had good thermal properties with glass-transition temperatures at 280 °C and 10 % weight loss temperatures in the range of 497–502 °C. Additionally, the contact angles in the thin-film state and electrospun fiber membranes were examined. The water contact angle of fiber membrane was improved compared to that of casting film which could reach to the 137 °. The resulting material exhibited stable luminescent intensity, possessed considerable thermal stability, and could be facilely processed into device for optical field applications.
