Three novel side-chain fluoroalkyl polyether oligomers with different molecular weight were synthesized base on the ring-opening polymerization of 3-perfluoro-n-butyl-1,2-epoxypropane, followed by terminal esterification using acryloyl chloride. The oligomer intermediates were used as functional monomers for emulsion copolymerization with methyl methacrylate, butyl acrylate, and hydroxyethyl methacrylate. The produced latexes were used for hydrophobic and oil-phobic finishing on cotton fabric surface and the treated cotton fabrics were tested by scanning electron microscopy and energy-dispersive spectroscopy, combined with chemical composition analysis by X-ray photoelectron spectroscopy. The result showed that fluorinated copolymers were successfully coated on the cotton fibers’ surface. Water contact angles was used to evaluate the wettability and the results showed that treated cotton fabrics possessed good hydrophobicity with the contact angle of 139.1 ± 1°, and the heat resistance of treated cotton fabrics was identified improved through the thermogravimetric analyses (TGA).

In this study, three novel side-chain fluoroalkyl oligoethers with different molecular weights were synthesised via a ring-opening reaction of 2,2,3,3,4,4,5,5,5-nonafluoropentyloxirane. The fluorooligoethers were then silanized and characterised by FT-IR,1H, and 19F NMR spectroscopies. These silanlized fluorooligoethers were used to fabricate hydrophobic coatings on silicon substrates, which were pre-treated with O2 plasma, by the method of liquid phase deposition. The chemical compositions and structures of the film surfaces were analysed by X-ray photoelectron spectroscopy and the results showed that silanized fluorooligoethers formed self-assembled films on the silicon wafer. The surface wettability of the coatings was measured by water contact angles. It is noted that the annealing process can improve the hydrophobicity with the highest water contact angle being 115.2 ± 1° and hexadecane contact angle being 67.2 ± 1°. The surface morphologies and roughness of the self-assembled films were measured by atomic force microscopy (AFM), as a result, the surface was found to be rougher with the increment of the molecular weight of the fluorooligoethers.

Two new perfluoroalkylated phthalocyanine derivatives were synthesised and characterised in order to investigate the effects of the fluorophobic/fluorophilic interactions on their mesophase and electronic properties. Both compounds exhibit columnar mesomo
