Oligomer-grafted nanofillers and advanced composites

摘要

Disclosed are oligomer-grafted nanofiller compositions and composites comprising oligomer-grafted nanofillers. Compositions of nanofillers grafted with oligomers for placement in a polymer matrix comprising a polymer derived from a plurality of polymerizable units comprising nanoparticles, one or more coupling groups attached to the nanoparticles , And one or more oligomers attached to the coupling group. In certain embodiments, the oligomer is derived from two or more polymerizable units, and at least one polymerizable unit is at least substantially similar to at least one of the polymerizable units of the polymer matrix. In another embodiment, the oligomer comprises two or more polymerizable units and improves the dispersion between the nanoparticles and the polymer matrix, interfacial strength, or both dispersion and interfacial strength. Composite materials and methods are also disclosed. [Selection] Figure 15
