Abstract:In this work, nanoporous zirconium-based MOFs materials (UIO-66, UIO-66-NH2) are introduced as fillers to enhance the mechanical properties of polydicyclopentadiene nanocomposites. MOFs/PDCPD are prepared by in-situ polymerization. Through infrared analysis and field emission scanning electron microscopy (FE-SEM), the effects of UIO particle function on the MOFs/PDCPD interface and the dispersion quality of nanoparticles in polydicyclopentadiene were studied. The mechanical properties of Zr-MOFs/PDCPD composites were studied by tensile test, unnotched impact test, bending test and other methods, and the optimal Zr-MOFs loading capacity was determined. The results show that when the UIO-66-NH2 content is 0.6%, the tensile strength, flexural strength, and impact strength of the composite material are increased by 29%, 30.8%, and 25.1% respectively compared with pure PDCPD. In addition, the modified composite The heat distortion temperature of the material has increased by 31.3%.
