Abstract
The invention relates to a method of bonding different materials of construction using hybrid materials comprising nanoscale, superparamagnetic, ferromagnetic, ferrimagnetic or paramagnetic powders enveloped or in part not enveloped by poly(meth)acrylates, and to their use.
Claims17
An adhesive, comprising:
- nanoscale superparamagnetic, ferromagnetic, ferrimagnetic, or paramagnetic particles not enveloped by poly(meth)acrylates;
- and
- a core comprising nanoscale superparamagnetic, ferromagnetic, ferrimagnetic, or paramagnetic particles enveloped by at least one shell comprising at least one poly(meth)acrylate,
- wherein the core comprises a matrix and domains,
- each of the domains is a region within the matrix, spatially separate from other domains,
- each of the domains comprises at least one magnetic metal oxide having a diameter of 2 to 100 nm, and
- the matrix comprises a non-magnetic metal oxide or metal dioxide.
