Title:ResearchonUHMWPE/CarbonBlackAntistaticCompositeMaterials
Abstract:
Ultrahighmolecularweightpolyethylene(UHMWPE)isastate-of-the-artengineeringplasticwithexcellentmechanicalpropertiesandhighwearresistance.However,itlackselectricalconductivityandissusceptibletostaticelectricitybuildup.Thiscanleadtonumerousissues,suchasdustadhesion,electricaldischargehazards,andreducedservicelife.Toaddressthesechallenges,thedevelopmentofUHMWPE/carbonblackantistaticcompositematerialshasgainedsignificantinterest.ThisresearchpaperaimstoprovideanoverviewofrecentadvancementsandthepotentialapplicationsofUHMWPE/carbonblackantistaticcomposites.
Introduction:
UHMWPEisknownforitsexceptionalmechanicalproperties,includinghighimpactstrength,lowfrictioncoefficient,andexcellentwearresistance.Itsuseextendstovariousfieldssuchasautomotive,aerospace,medicaldevices,andsportsequipment.However,staticelectricityaccumulationonUHMWPEsurfaceshindersitsperformanceandmakesitunsuitableforcertainapplications.Toovercomethislimitation,theincorporationofconductivefillers,suchascarbonblack,intoUHMWPEmatrixhasbeenexploredtodevelopantistaticUHMWPE-basedcomposites.
