Sr2+ was chemically grafted onto the hydroxyl position of bacterial cellulose. FTIR and UV-Vis spectroscopy were employed to evaluate the chemical bonding of the modified structure of the bacterial cellulose. Chemical bonding between Sr-O was then formed. The existence of strontium was confirmed using XRF. Significant enhancement of the dielectric properties was observed. Next, a small amount of modified bacterial cellulose was prepared as a binary blend composite. The ratio between the poly vinylidene fluoride and the modified bacterial cellulose was investigated. Thermal stability and the mechanical properties were superior to these of the neat modified bacterial cellulose. The degradation temperature was higher than 300๐C. The outstanding property of the composite was its flexibility. The excellent properties of the modified bacterial cellulose and poly vinylidene fluoride composite make it a good candidate as an electro-active bio-composite.
