PVA Bio Composites: Dielectric behavior of PVA Bio composites,Used
Delivery time: 8-12 business days (International)
The development and electrical characterization of Sisal powder filled Polyvinyl alcohol (PVA) composites is reported. Effect of temperature and frequency variation on dielectric constant (e), dielectric dissipation factor (tan d) and on a. c. conductivity (sa.c.) were determined. With the increase of filler content, the dielectric constant increased, it was mainly due to motion of the dipolar groups of the interfacial polarization occurring in the composites. The conductivity increased with rise in temperature. Differential scanning calorimetry (DSC) scans were run by using a Mettler DSC. Tm of PVA was little affected on adding untreated sisal fibre powder .On adding treated sisal fibre a new degradation peak appeared around 290 oC.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
