Hisfieldof research issurfacechemistry, surface electrochemistry, and corrosion science, with emphasis on the understanding of thestructureandpropertiesofmetalandalloysurfaces.Hisresearchinterestsincludethegrowthmechanismsand structure of oxide layers on metals and alloys in gaseous and aqueous environments, adsorption ofinorganic, organic and biomolecules, themechanisms of corrosion ofmetals and alloys at the nanoscale,passivity,passivitybreakdownand localizedcorrosion, initialstagesofhigh temperatureoxidation,and theapplications of advanced surface analyticalmethods such as X-ray Photoelectron Spectroscopy, ScanningTunnellingMicroscopyandSpectroscopy,andTime-of-FlightSecondaryIonsMassSpectrometry.Dr.Marcushas published over 400 papers in scientific journals, books and conference proceedings in the areas ofcorrosionscience,surfacechemistryandelectrochemistry,surfaceanalysisandmaterialsscience,plustwobooks “CorrosionMechanisms in Theory and Practice” and “AnalyticalMethods in Corrosion Science andEngineering”.Hehasgivenover100invitedlecturesatInternationalConferences.HeservesorservedontheeditorialboardoffivemajorjournalsinElectrochemistryandCorrosion:ElectrochimicaActa,CorrosionScience,MaterialsandCorrosion,CorrosionEngineering,Science,andTechnology,andCorrosionReviews.Pr.Marcushasreceivedanumberofawardsandhonors,includingthe2005UhligAwardfromtheElectrochemicalSociety,the2008WhitneyAwardfromNACEInternational,theCavallaroMedaloftheEuropeanFederationofCorrosionin2008,theU.R.EvansAwardoftheUKInstituteofCorrosionin2010,theLeeHsunAwardoftheInstituteofMetalsResearchof theChineseAcademyofSciences in2012.Hewas theD.B.RobinsonDistinguishedSpeakeroftheUniversityofAlberta,Edmonton,Canadain2013.HeisanelectedFellowoftheElectrochemicalSociety(2005)andoftheInternationalSocietyofElectrochemistry(2009).

ABSTRACT:

Thesurfaceofmaterialsofteninteractswiththeenvironment,whichmaybeagas(e.g.air)oraliquid(e.g.water). This interaction can be detrimental to the material and cause its degradation by corrosion.

Thermosetbased lightweightconstructionmaterialsareused inmany industriesduetotheirhigh(thermo)mechanical performance. However, the cross-linked structure of the thermosets, which is responsible fortheirgoodperformance,isnotalwaysanadvantage.Conventionalrecyclingandrepairmethodsareoftennotapplicableforthermosettingpolymers.Themostfrequentlyusedrecyclinganddisposalmethodsforthermosetcomposites,whicharelandfilling,burningorgrindingintoarawpowder,arenotefficient.Thestate-of-the-artrepairmethodsaremostlybasedonremovingthedamagedareabygrindingormilling,followedbystickingnewlayersevenifthecompositeisonlyde-laminated.Inthecaseofadelamination,itwouldbemoreefficienttoremovethedam-agedmatrixwithoutdamagingtheendlessfibers.ForthisreasonFraunhoferPYCOdevelopedasimple,efficientandquickrecyclingandrepairmethodforcyanate-andcyanate-epoxide-basedcomposites.Cyanatesare formedviacyclotrimerization reaction fromat leastdifunctionalcyanatemonomers,showinghighglasstransitiontemperatures,thermalsta¬bilityandhighme-chanicalstrengthaswellasalotofotherexcellentproperties.Furthermore,cyanatescanreactwithavarietyofcompounds,e.g.epoxides,givingthepossibilitytoproducepolymerswithtailor-madeproperties,forexampleforapplica¬tionsacquiringfastcuringorcuringatlowtemperatures.Regardingtotherecyclingprocess,thematrixresincanbedecomposedandfiberswithgoodpropertiescouldberegained.Therecyclingofcyanateesterscanbedoneunderrela¬tivelymild conditions (from room temperature up to 190 °C) using a special class of agents, producing triazine-containing structures, aswell as phenols.
