The mesoporous silica, the silica tube and the polyhedral oligomeric silsesquioxane are discussed in the context of decreasing the dielectric constant of PI, and the prospects for the development of low dielectric constant PI materials The preparation by adding porous materials into PI can produce pores with supporting structures, leading to low dielectric properties and good mechanical properties of the composite. It is a new way to prepare PI of low dielectric constant., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=B4YNQt5UEkRjV4Ffd10c3g==, pdfFileSize=453868, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=1.
