Through　construction　of　a　three-dimensional　continuous　ceramic　network,　the　dielectric　performance　of　polymer　composites　can　be　enhanced　with　a　reduced　amount　of　ceramic　loading.　However,　the　commonly　employed　methods,　such　as　freeze　casting　or　sacrificial　template,　fail　to　precisely　control　the　structure　of　the　ceramic　skeleton,　leading　to　significant　randomness　in　content　control.　In　this　work,　a　Digital　Light　Processing　(DLP)　3D　printing　technique　is　utilized　to　precisely　fabricate　ordered　three-dimensional　ceramic　structures,　which　are　further　sintered　at　high　temperatures　to　obtain　a　continuous　barium　titanate　(BT)　skeleton　(BTS).　This　is　then　compounded　with　cyanate　ester　based　polymers　(CP)　to　prepare　BTS/CP　composites.　Results　show　that　when　the　content　of　BT　is　61.2　vol%,　the　dielectric　constant　of　the　composite　is　657　at　100　Hz,　which　is　about　173　times　higher　than　CP,　while　maintaining　a　lower　dielectric　loss　of　0.026.　Interestingly,　the　distribution　of　BTS　in　the　composites　has　a　significant　impact　on　the　dielectric　performance　of　the　composite.　When　the　BT　content　is　about　50　vol%,　the　dielectric　constant　of　the　“fine　and　dense”　skeleton　composite　is　2.1　times　higher　than　that　of　the　“coarse　and　sparse”　skeleton　composite.　This　study　proposes　a　novel　strategy　for　building　a　structurally　and　compositionally　controllable　three-dimensional　barium　titanate　(BT)　network　within　polymers,　demonstrating　the　noteworthy　influence　of　macrostructure　on　the　dielectric　performance　of　polymer　composites.　This　offers　a　fresh　approach　to　the　mass　application　of　ordered　three-dimensional　ceramic　skeleton　enhanced　polymer　composites　in　the　fields　of　electronics　and　electricity.　©　2024　Elsevier　Ltd
