Název v původním jazyce

Tailored expanded graphite based PVDF porous composites for potential electrostatic dissipation applications

Popis výsledku v původním jazyce

Electronic components are susceptible to damage from ESD. Sufficient electrical conductivity is required to dissipate electrostatic charge build-up brought about by the charged orbital environment. In this work, the composites with surface and volume resistivity sufficient to mitigate electrostatic charge build-up (105-1011 Ω) are prepared by incorporation of a low loading level of EG in PVDF polymer matrix with the approach of water immersion phase inversion. Because the porous surface structure and the residual of PVP endow the composites with good hydrophilicity, which promotes the electric charge to escape quickly through the water after the composites absorb the water from the air. Meanwhile, the incorporation of EG can improve the mechanical strength and thermal stability of composites. Such advanced materials can be designed for potential applications in a variety of industries where ESD protection and contamination control are required.
