Polytetrafluoroethylene–nanocellulose composites with negative in-plane thermal expansion and low relative permittivity

Abstract Low-dielectric materials for advancing telecommunication technologies must exhibit a low coefficient of thermal expansion (CTE), low relative permittivity ( ε ), and low dielectric loss tangent (tan δ ) at frequencies > 10 GHz. However, these properties are difficult to...
