STUDY ON INTERFACE STATE AND MECHANICAL BEHAVIOR BETWEEN NCA/POLYMER CHAIN

The nanoparticle chain aggregates (NCA) posessed of elastic behavior was described. Elastic NCA is importance infection for nanoparticles dispersed on polymer. The adsorption and twining between the polymer chain/NCA can better intercept the stress propagation through the matrix. At the same time, the nanoparticles chains also have the connection effective in the matrix, when NCA are pulled out and make the matrix deform and crack, but the NCA can not be pulled out completely until fracture at the neck of the NCA. The stress can be transferred by the necks from the matrix to the NCA, so the mechanical properties of the composites are insensitive to the interface between the polymer chain/NCA. It shows that the roughly surface of spherical particles might contributed to reinforcing polymer.
