高分子炭黑复合材料流变行为-导电功能的相关性研究的综述报告 Abstract Polymercarbonblackcompositeshavebeenwidelystudiedasaconductivematerialduetotheirgoodelectricalandthermalproperties.Understandingtherheologicalbehaviorofpolymercarbonblackcompositesiscrucialfordesigningandprocessingsuchmaterials.Inthisreview,wesummarizerecentresearchontherheologicalbehaviorofpolymercarbonblackcomposites,withafocusontherelationshipbetweentherheologyandtheconductivityofthematerials.Wealsodiscusssomefuturedirectionsforresearchinthisarea. Introduction Polymercarbonblackcompositesareaclassofmaterialsthatarewidelyusedinavarietyofapplicationssuchasconductivecoatings,electromagneticinterferenceshieldingmaterials,andbatteryelectrodes.Theexcellentelectricalconductivityofcarbonblack,combinedwiththeflexibilityandprocessabilityofpolymers,makesthesecompositesparticularlyattractiveforsuchapplications.Theconductivityofpolymercarbonblackcompositesdependsonvariousfactors,includingthecarbonblackcontent,theparticlesizeanddistribution,thepolymermatrix,andtheprocessingconditions.Therefore,understandingtheeffectofthesefactorsontheconductivityandtherheologyofthecompositesisimportantfordesigningandprocessingsuchmaterials. RheologicalBehaviorofPolymerCarbonBlackComposites Therheologicalbehaviorofpolymercarbonblackcompositesisinfluencedbyvariousfactorssuchasthecarbonblackcontent,theparticlesizeanddistribution,andthepolymermatrix.Therheologicalpropertiesofpolymercarbonblackcompositesaremeasuredusingtechniquessuchasdynamicrheology,steady-stateshear,andoscillatoryshear.Studiesontherheologicalbehaviorofpolymercarbonblackcompositeshaveshownthatthecompositesexhibitnon-Newtonianflowbehavior,whichcanbemodeledusingthepower-laworHerschel-Bulkleymodel.Thedegreeofnon-Newtonianbehaviorincreaseswithincreasingcarbonblackcontentanddecreasingparticlesize.
