二维MXene/零维钛酸铜钙杂化填料协同增强的高介电聚偏氟乙烯复合材料及其宽温域稳定性
Enhanced dielectric properties and wide-temperature stability of polyvinylidene fluoride composites reinforced with 2D MXene/0D calcium copper titanate hybrid fillers
摘要
Abstract
Polyvinylidene fluoride(PVDF)composites were fabricated by incorporating two-dimensional(2D)Ti₃C₂TₓMXene nanosheets and zero-dimensional(0D)calcium copper titanate(CCTO)nanoparticles as hybrid fillers.Micro-structural analysis reveals good interfacial compatibility between the fillers and polymer matrix,along with uniform filler dispersion.The resulting PVDF composites exhibit excellent surface quality(roughness less than 1/10 000)and remark-able dielectric performance.With the addition of 2 phr(parts per hundred rubber)Ti₃C₂Tₓ MXene and 10 phr CCTO,the composite achieved a high dielectric constant of 21.27 while maintaining a relatively low dielectric loss(<0.038).The enhanced dielectric constant can be attributed to the intensified interfacial polarization between the fillers and polymer matrix,as well as the formation of micro-capacitors within the composite structure.Furthermore,the CCTO/MXene/PVDF composites exhibit stable dielectric properties across a wide temperature range from room temperature to 160℃,indicating excellent temperature stability of the dielectric parameters.These results demonstrate that incorporating hybrid fillers of different dimensions significantly enhances the dielectric properties of polymer matrix composites while impart-ing high-temperature stability,making them promising candidates for high-temperature applications.关键词
