Fabrication, structure and properties of epoxy/metal nanocomposites
Gd2O3 nanoparticles surface-modified with IPDI were compounded with epoxy. IPDI provided an anchor into the porous Gd2O3 surface and a bridge into the matrix, thus creating strong bonds between matrix and Gd2O3 . 1.7vol.-% Gd2O3 increased the Young’s modulus of epoxy by 16–19%; the surface-modified...

| 总结: | Gd2O3 nanoparticles surface-modified with IPDI were compounded with epoxy. IPDI provided an anchor into the porous Gd2O3 surface and a bridge into the matrix, thus creating strong bonds between matrix and Gd2O3 . 1.7vol.-% Gd2O3 increased the Young’s modulus of epoxy by 16–19%; the surface-modified Gd2O3 nanoparticles improved the critical strain energy release rate by 64.3% as compared to 26.4% produced by the unmodified nanoparticles. The X-ray shielding efficiency of neat epoxy was enhanced by 300–360%, independent of the interface modification. Interface debonding consumes energy and leads to crack pinning and matrix shear banding; most fracture energy is consumed by matrix shear banding as shown by the large number of ridges on the fracture surface. |
