摘要: The effect of biofouling on physical, chemical and mechanical changes Bisphenol A polycarbonate im- mersed at a depth three meters two different locations (Port FSI, Chennai, India) in the Bay Bengal Sea over period six months was subject this study. Biofouling terms total suspended solids, organic matter viable count higher Port than probably because dissolved oxygen former latter site. An increase glass transition temperature (from 133°C to 147 144°C FSI respectively) observed samples indicating loss amorphous region conformational change polymer. fold decrease ten- sile strength, 33% contact angle and, reduction tertiary methyl carbonate carbonyl indices were observed. These findings indicate that undergoes combination biodeterioration biodegradation un- der these conditions.
