A new type of cyclo-linear structured high phenyl content siloxane elastomer (Ph-CLS-E) is prepared through “one-pot” hydrosilylation reaction that take advantage of the reactivity differences of the cyclic, linear precursors...

Construction of segregated structure is an effective way of preparing highly conductive composite. Here, we report an environmentally friendly method to prepare highly conductive linear low‐density polyethylene/graphene nanoplatelets composite with segregated structure (s‐LLDPE/GN) and low GN content. Firstly, GN coated LLDPE granules are prepared through aqueous dispersing and gradually drying. Then, the s‐LLDPE/GN composites are obtained by melting and self‐leveling without extra pressure. This method not only favors the forming of GN segregated network, but also allows certain fusing of the polymer at the interfaces that contribute to good mechanical strength of the composite. The electrical conductivity of the composite increases to 4.5 S/m when the GN content is 1.0 wt%. The composite with 0.5 wt% GN shows 10−1 S/m electrical conductivity, and retains 82% of the tensile strength of pure LLDPE. The facile and green process in this method can be applied in many other polymer composites and show high potential for industrial application.
