An adhesive composition degradable by dielectric heating. The adhesive composition comprises a thermosetting polymer and a material sensitive to dielectric heating. The material sensitive to dielectric heating is selected from any one or more of hollow nanospheres, nanotubes, nanorods, nanofibres, nanosheets, graphene, graphene derivatives, nano/micro hybrids and mixtures of two or more nanoscale particles. The adhesive composition may be particularly useful in the assembly and disassembly of parts, particularly parts which have complicated and/or blocked joined surfaces. A method of joining at least two parts of an article together and a method of disassembling at least two parts of an article, using the adhesive composition are also provided. The adhesive composition may provide a reworkable nano-composite adhesive. The adhesive composition may be used to reversibly bond a biomedical or dental implant to a part of a human or animal body.

A low-voltage varistor includes a cured body of a resin composition for forming the low-voltage varistor. The resin composition includes: (A) at least one selected from carbon nanotubes and carbon aerogels; and (B) at least one selected from epoxy resin and acrylic resin.

A method for making a carbon nanotube composite structure includes providing a polymer substrate having a first surface and a second surface opposite to the first surface.
