摘要：
The polyvinylidene fluoride (PVDF)/multiwall carbon nanotube (MWCNT) composites, prepared by solution casting technique, can be used as electromagnetic interference (EMI) shielding material. The PVDF matrix shows MWCNT-dependent EMI shielding effectiveness, skin depth, morphology, mechanical, and dynamic mechanical properties. The transmission electron microscopy and field emission scanning electron microscopy images depict dispersion and distribution of MWCNT in PVDF matrix. The differential scanning calorimetry reveals MWCNT dependent crystalline melting temperature. The MWCNT is acting as reinforcing filler for PVDF matrix. The crystalline melting of PVDF and PVDF/MWCNT composites shows the occurrence of two endothermic peaks. Dynamic mechanical analysis of composites reveals MWCNT-dependent damping characteristics and storage modulus.
