Abstract
A flexible heat-dissipating sheet including a composite layer of filler and polymer resin is provided. The heat-dissipating sheet is obtained by dispersing a polymerization catalyst in a polymerizable thermoplastic resin and blending them with each other to form a thermoplastic resin composition, and mixing fillers with the thermoplastic resin composition, applying the resultant mixture onto a substrate film, followed by heating to carry out in-situ polymerization and to allow the composite layer of fillers and thermoplastic resin to be adhered to the substrate film. The heat-dissipating sheet has excellent heat-dissipating properties, i.e. heat conductivity, particularly in-plane heat conductivity, and shows improved physical properties, including mechanical properties and thermal properties, etc.
