“…The NFD diamine led to polyetherimide bearing two side chains -CH 2 C 4 F 9 [11] per monomer unit whereas the TFD diamine [12] that is the subject of this article, led to polyetherimide bearing one side chain -CH 2 C 6 F 13 per monomer unit. The scheme of the synthesis of fluorinated copolyetherimides by the step reaction of BAPA with various mixtures of m-PDA and TFD is shown in Fig.…”

Step polymerization of bisphenol-A diphthalic anhydride (BAPA) with various mixtures from m-phenylene diamine (m-PDA) and 2-(perfluorohexylmethyl)butan-1,4-diamine (TFD) led to hydrophobic copolyetherimides bearing R F = -CH 2 -C 6 F 13 side chains that were characterized by NMR, elementary analysis, DSC, TGA and surface energy analysis. By increasing the TFD unit%, the glass transition temperature (T g ) decreases according to the Fox equation from 217 8C (m-PDA 100% and TFD 0% like in ULTEM TM 1000) to 113 8C (m-PDA 0% and TFD 100%). Similarly, the surface energy (g s ) decreases from 45.3 mJ m À2 to 27.4 mJ m À2 . The thermal decomposition temperature (T d for 5% weight loss under argon) is slightly affected by introducing TFD units compared with T d for ULTEM TM and it is close to 400 8C. The best compromise between thermal stability, hydrophobic and organophilic properties as well as the ability to form a soft nonporous film by the cast-evaporating method led us to select the copolyetherimide with m-PDA 25% and TFD 75% for which T g = 121 8C, T d = 400 8C and g s = 30.8 mJ m À2 . # 2005 Published by Elsevier B.V.

An aromatic diamine monomer, 1H,1H-perfluorooctyl 3,5-diaminobenzoate (PFD), was synthesized in three steps, which was used to prepare the polyimides containing pendant perfluoroalkyl chains via the polymerization of PFD with commercial 4,4′-(hexafluoroisopropylidene)diphthalic anhydride. Various characterization techniques including thermogravimetric analysis, infrared spectroscopy, and X-ray photoelectron spectroscopy were used to characterize the new polyimides with perfluoroalkyl chains. The resulting polyimide film exhibits hydrophobicity with a contact angle of 95° for water, and the calculated surface free energy is 37.4 mN m−1. Superhydrophobic surfaces were also demonstrated by coating the polyimide containing pendant perfluorooctyl chains on rough alumina substrate.
