Flexible EMI Shielding Materials Using Conducting Copolymers
Abstract
Tactical shelters used by the Army are constructed from metallic sheet materials, which provide high electromagnetic shielding interference (EMI) protection. Because these materials provide no flexibility, they will not meet the future needs of the Army. There is therefore a need for materials with high electrical shielding characteristics in a light weight, tent like, flexible fabric to enable a rapidly erectable and collapsible capability. The work described herein involves the research and development of flexible EMI shielding materials using metallic mesh or knitted wire mesh sandwiched between two sheets of an electrically conducting copolymer which is elastomeric in nature. The rationale for using a conducting polymer matrix is that a perforated barrier (wire screen) cannot give better shielding than a homogeneous one, everything else being equal.
