Provided are a thermosetting resin composition and a prepreg, laminate and printed circuit board using same. The thermosetting resin composition comprises a resin component, the resin component comprising a modified cyclic olefin copolymer having a structure as shown in formula I and another unsaturated resin. By introducing a methacrylate end group having a certain polarity into a cyclic olefin copolymer, a modified cyclic olefin copolymer is formed. The modified cyclic olefin copolymer can form a thermosetting material by means of cross-linking with itself or another unsaturated resin, whereby the bonding property can be significantly improved while retaining the excellent dielectric properties of the cyclic olefin copolymer itself. The laminate prepared using the thermosetting resin composition has good dielectric properties, a good peel strength and a good heat resistance, and can meet all the performance requirements for printed circuit board substrates in the current high-frequency and high-speed communication field.

The present invention is directed to the production of stretchable wrinkled film electrodes for use in wearable/portable ROC systems using electrochemical analysis techniques. A polymer layer is disposed on a conductive substrate and a sacrificial layer is disposed on said polymer layer. An electrode shape template is cut out of adhesive and disposed on the sacrificial layer. A metallic film is disposed on the sacrificial layer by the electrode shape template. The disposed layers are removed from the conductive substrate and placed in an oven to allow said layers to shrink. The shrunken metallic film is treated with a solution to promote bonding between the film and an elastomer. The elastomer is drop-cast onto the shrunken film and the sacrificial layer is dissolved to detach the shrunken polymer layer. The shrunken film and elastomer are placed in a chemical bath and dried, producing the stretchable wrinkled film electrode.
