Polyethylene is considered to be as one of the simplest polymer, it has ethene or ethylene as the monomer unit whereas the linear polymer is known as the high density polyethylene-HDPE. However, the majority of polymers or plastics used for engineering design are synthetic and often they are specifically formulated or “designed” by chemists or chemical engineers to serve a specific purpose. <<197A46634A2FDC458F48EDD045036786>]/Prev 389023/XRefStm 2357>> This can be accomplished by coating the conducting polymer over an insulating surface.
