Piezoelectric property from processed crustacean shells

Abstract

The piezoelectric film was developed from bio waste crustacean of Prawn Shells (PS) and Crab Shells (CS). The absorption peak was optically canvassed at 266 nm and 377 nm for processed PS and at 249 and 276 nm for processed CS, respectively. The processed PS is about 40-46% and CS is about 40−43% transmittance in the spectral visible region. The structural and crystallographic features of processed PS and CS were studied by Fourier Transform Infrared Spectroscopy (FTIR). The coexistence of intra and inter-molecular hydrogen bonds is also apparent from the vibrational bands of 3145 cm−1 and 3011 cm−1 for PS and 3328 cm−1 and 3159 cm−1 for CS, respectively. The presence of amino acids in the triple helix structure of the polypeptide chains in prawn and crab shell is confirmed by Raman spectroscopy. The flexibility of processed crustacean of prawn and crab shell film will be utilized as energy harvesting contrivance applications.
