Preparation and characterization of moulded shapes from Egyptian corncobs‐bisphenol polycondensate resins and aluminium powder

Abstract

Different types of moulded shapes were prepared from Egyptian corncobs‐bisphenol polycondensate resins and aluminium powder. Modifications of the produced resin with phenol‐formaldehyde, naphthalene‐formaldehyde, and anthracene‐formaldehyde, were performed. The electrical conductivity of the samples increases with the increase of temperature and aluminium concent. All samples reveal semiconducting behaviour.

Dielectric Modulus Relaxation and Hopping Conduction Mechanism of Bisphenol A Corncobs Polycarbonate

“…In the past few years, a rapidly growing demand for bisphenol A in industrial scale is for use in high-tech production, such as compact discs and digital video discs [1][2][3][4]. Bisphenol A corncobs (BPACC) is synthesized through the condensation reaction of BPA and the powder of Egyptian corncobs [5,6]. Both chemical analysis and IR spectroscopy have shown that BPACC resin has a complicated structure.…”
