Effect of the structural parameters of a series of fluoromonoacrylates on the surface properties of cured films

Journal of Polymer Science Part A Polymer Chemistry (2001)

Bruno Améduri Roberta Maria Bongiovanni V. Lombardi Antonino Pollicino Aldo Priola

Abstract A series of fluorinated acrylates [F(CF 2 ) q (CH 2 ) p OCOCHCH 2 , where q = 8 and p = 2 ÷ 11) were synthesized and used as comonomers in the photopolymerization of acrylic systems. These fluoroacrylates were synthesized in a three‐step procedure through the radical addition of perfluoroalkyliodides to an unsaturated alcohol followed by their acrylation. The mixtures, containing up to 0.8% (w/w) of the comonomers, produced transparent films after UV curing; they showed changes in the surface properties as a function of the comonomer type and concentration. With contact‐angle and X‐ray photoelectron spectroscopy analyses, the relationship between the structure of the monomers and the surface properties of the UV‐cured films was investigated: the wettability decreased, depending on the length of the fluorinated group ( q value) and the hydrogenated segment of the monomer ( p value). © 2001 John Wiley & Sons, Inc.

Cellulases are enzymes with great potential for converting biomass to biofuels for sustainable energy. However, their commercial use is limited by their costs and low reusability. Therefore, the scientific and industrial sectors are focusing on finding better strategies to reuse enzymes and improve their performance. In this work, cellulase from

Surface rearrangements of polymeric materials containing fluorinated chains as studied by contact angle and other methods

CRC Press eBooks (2014)

Roberta Maria Bongiovanni V. Lombardi A. Priola

olymeric films were prepared from different methacrylic copolymers containing perfluoropolyether chains of the type: CF3CF2O (CF2CF2O)(m)(CF2O).CF2- Investigations of the films by dynamic contact angle measurements and by X-ray photoelectron spectroscopy showed a considerable difference between the surface and the bulk composition, with highly hydrophobic and lipophobic outermost layers created by the alignment of the perfluoroalkoxy groups. On the two sides of the polymer films different surface characteristics were found depending on the substrate employed. A dynamic surface rearrangement was observed when the films were exposed to different environments; depending on the chemical composition and the structure of the films, the restructuring was found to be reversible to the original state.

New acrylic‐allylic resins containing perfluoropolyether chains for UV‐cured coatings

Pigment & Resin Technology (1999)

V. Lombardi Roberta Maria Bongiovanni Giulio Malucelli Aldo Priola Silvia Garavaglia

New acrylic and allylic resins were prepared by functionalising perfluoropolyethers chains, which assured peculiar surface properties. Blends having a different amount of the acrylic and of the allylic systems were cured in air by UV irradiation. The cure of the films was found dependent on the ratio between the two resins; the concentration for the obtaining of a film fully cured in air was determined. On the basis of this concentration, a macromer functionalised with the right amount of both the acrylic group and the allylic one was synthesised.
