• Surface modification of silk fibroin fibers with poly(methyl methacrylate) and poly(tributylsilyl methacrylate) via RAFT polymerization for marine antifouling applications
  1 March 2015

  Buga, M.-R.; Zaharia, C.; Bălan, M.; Bressy, C.; Ziarelli, F.; Margaillan, A. Materials Science and Engineering: C, 2015, 51, 233–241
  Abstract : In this study, silk fibroin surface containing hydroxyl and aminogroups was firstly modified using a polymerizable coupling agent 3-(trimethoxysilyl) propyl methacrylate (MPS), in order to induce vinyl groups onto the fiber surface. The reversible addition–fragmentation chain transfer (RAFT)-mediated polymerization of methyl methacrylate (MMA) (…)

• Comparative effects of humid tropical weathering and artificial ageing on a model composite properties from nano- to macro-scale
  2 November 2015, by webmaster

  Belec, L.; Nguyen, T. H.; Nguyen, D. L.; Chailan, J. F. Composites Part A: Applied Science and Manufacturing 2015, 68, 235–241
  Abstract :
  The effects of humid tropical conditions and artificial ageing tests on a UD glass-fibre/epoxy composite are compared at different scales. A modified network of 500 nm width around each fibre is identified by AFM force measurements. The evolution of this interphase is correlated to the composite embrittlement observed in transverse bending tests (…)

• Multiscale investigation of the effect of sizing chemistry on the adhesion and interfacial properties of glass fiber-reinforced epoxy composites
  27 September 2022

  S. Assengone Otogo Be, A. Fahs, L. Belec, S. Belkessam, G. Louarn, J.-F. Chailan, Polymer Composites, 2022, 1-13. https://doi.org/10.1002/pc.27064
  Abstract
  The objective of the present work is to understand how the main constituents of sizing modify the interfacial strength, the mechanical properties of epoxy composites as well as their durability. In this study, two model interphases between E-glass fibers and epoxy resin were designed and studied in terms of adhesion and mechanical (…)

• Hydrolyzable Additive-Based Silicone Elastomers: A New Approach for Antifouling Coatings
  5 March 2020

  Gevaux, L.; Lejars, M.; Margaillan, A.; Briand, J.-F.; Bunet, R.; Bressy, C. Hydrolyzable Additive-Based Silicone Elastomers: A New Approach for Antifouling Coatings. Polymers 2019, 11 (2), 305
  Abstract : Fouling Release Coatings are marine antifouling coatings based on silicone elastomers. Contrary to commonly used biocide-based antifouling coatings, they do not release biocides into the marine environment, however, they suffer from poor antifouling efficacy during idle periods. To (…)

• Photo-oxidative degradation behavior of linseed oil based epoxy resin
  1 February 2017

  Dupuis, A.; Perrin, F.-X.; Ulloa Torres, A.; Habas, J.-P.; Belec, L.; Chailan, J.-F. Polymer Degradation and Stability 2017, 135, 73–84
  Abstract : The photo-oxidation behaviour of a biobased epoxy polymer has been studied under irradiation at wavelengths > 315 nm at 45°C and in the presence of oxygen. The resin is obtained after curing a blend of an epoxidized linseed oil (ELO) and epoxidized glycerol (EG) with methyltetrahydrophtalic anhydride (MTHPA). Molecular changes induced by the (…)

• Spatio-temporal variations of marine biofilm communities colonizing artificial substrata including antifouling coatings in contrasted coastal environments
  22 February 2018

  Briand Jean-François, Barani Aude, Garnier Cédric, Réhel Karine, Urvois Félix, Le Poupon Christophe, Bouchez Agnès, Debroas Didier, Bressy Christine, Spatio-temporal variations of marine biofilm communities colonizing artificial substrata including antifouling coatings in contrasted coastal environments, Microbial Ecology (2017) 74, 585-598
  Abstract : Surface colonization in seawater first corresponds to the selection of specific microbial biofilm communities. By coupling flow (…)

• Temporal covariation of epibacterial community and surface metabolome in the Mediterranean seaweed holobiont Taonia atomaria
  10 July 2019

  Paix, B.; Othmani, A.; Debroas, D.; Culioli, G.; Briand, J. Temporal Covariation of Epibacterial Community and Surface Metabolome in the Mediterranean Seaweed Holobiont Taonia atomaria . Environ Microbiol 2019, 1462-2920.14617. https://doi.org/10.1111/1462-2920.14617.
  Abstract : An integrative multi-omics approach allowed monthly variations for a year of the surface metabolome and the epibacterial community of the Mediterranean Phaeophyceae Taonia atomaria to be investigated. The (…)

• Cystophloroketals A–E, Unusual Phloroglucinol–Meroterpenoid Hybrids from the Brown Alga Cystoseira tamariscifolia
  31 July 2015

  Hattab, M. El; Genta-Jouve, G.; Bouzidi, N.; Ortalo-Magné, A.; Hellio, C.; Maréchal, J.-P.; Piovetti, L.; Thomas, O. P.; Culioli, G. Journal of Natural Products, 2015, 78 (7), 1663–1670
  Abstrat:
  Cystophloroketals A-E (1-5), five new phloroglucinol-meroditerpenoid hybrids, have been isolated together with their putative biosynthetic precursor, the monocyclic meroditerpenoid 6, from the Mediterranean brown alga Cystoseira tamariscifolia. They represent the first examples of (…)
