Fabrication of Nanobiocomposites

The thermal stability of nanobiocomposites was analyzed up to 500°C with a heating rate of 10°C/min under the atmosphere with flow rate of 100 ml/min. Changes in weight percentage and the decomposition temperatures of the samples were recorded with a thermogravimetric analyzer (TGA Q 500, TA Instruments). Approximately 10 mg of each sample were loaded for each measurement. 

The dimension change and coefficient of thermal expansion (GTE) of nanobiocomposites were analyzed from 30 to 100°G at a heating rate of 5°G/min under the atmosphere with flow rate of 100 ml/min. The probe was applied at 0.05 N loading and it measured strain and temperature of specimens. The GTE was taken as the linear slope of the dimensional stability-temperature curve with a thermomechanical analyzer (TMA Q 400, TA Instruments). The specimen dimension was 7.0 mm x 7.0 mm X 1.7 mm. 

The storage modulus, loss modulus, tan delta, and glass transition temperature of nanobiocomposites were analyzed from -30 to 100°G at a heating rate of 5°G/min under 

The surface morphologies of fractured surfaces of nanobiocomposites were observed with scanning electron microscope (SEM, S-4800, Hitachi, Japan) and energy dispersive X-ray (EDX). The fractured surface of biocomposites was prepared with impact test specimens. Prior to the observation, all the specimens were coated with Au in order to prevent electrical discharge. The acceleration voltage used was 15-25 kV.
