Supercritical Carbon

Polyester fabric was pretreated with 3-aminopropyltrimethoxysilane (APTMS) through supercritical carbon dioxide (scCO2) process before electroless copper plating. APTMS pretreated polyester fibers were characterized by contact angle. Deposit weight, surface morphology and electromagnetic interference (EMI) shielding effectiveness (SE) of electroless copper plated polyester fabrics were investigated. The results show that polyester fibers are covered with APTMS after APTMS modification in scCO2 medium. Copper coatings on the polyester fibers are uniform after copper plating. Electromagnetic interference shielding effectiveness of the copper plated polyester fabric arrives at 60-80dB at frequencies ranging from 2 to 18 GHz.

Shielding Material

In order to obtain the electromagnetic shielding material, the lightweight flakes of poplar are selected to be the substrate. After the electroless copper plating, the flakes turn to electric cell which is made by hot-press with bicomponent epoxy, and it turn to electromagnetic shielding materials. In this paper, the electromagnetic shielding effectiveness of electromagnetic shielding materials is investigated. The results indicates that the reasonable ratio of main components of the electroless copper plating is: copper sulfate 80g/L, reducing agent 90 g/L, K-Na tartrate (TART) 65 g/L, EDTA•2Na100 g/L, α, α'-dipyridyl 10mg/L, potassium ferrocyanide 50 mg/L. In the testing of Hertzian waves between 9 kHz～1.5GHz, the average effectiveness of electromagnetic shielding is 60.4dB.
