Antistatic effect of glycerol monostearate on volume resistivity and mechanical properties of nanocomposite polystyrene-nanocrystal cellulose
Abstract
Research on polymer-based nanocomposite polystyrene (PS) and nanocrystalline celluloses (NCCs) using antistatic agent of glycerol monostearate (GMS) for materials engineering has been done. The research was carried out in several stages. First, the matrix was made by mixing PS with BPO into laboplastomil at room temperature for three minutes at 50 rpm, followed by the addition of MA at the same time. Second, the above mixture was dissolved in toluene over a magnetic stirrer for three hours at room temperature until a viscous liquid was formed. A variety of concentrations of NCCs and GMS were added into the above mixture at a temperature of 60°C with rotational speed of 700 rpm. Third, the viscous liquid mixture was poured into the watch glass coated with aluminum foil. After hardened, the nanocomposite was pressed at a temperature of 90°C with a pressure of 1800 kgf. Subsequently, the samples were prepared for further characterization, namely tensile, structural, morphological, and Volume resistivity tests. Because of its high surface area, the addition of NCCs is able to improve the mechanical properties of the nanocomposite. IR spectra showed that there is physic interaction between PS, NCCs, and GMS. The result of nanocomposite tensile test with the addition of 1-5% GMS showed the highest value was obtained by the addition of 3% GMS with Young's modulus of 910.70 MPa and Volume resistivity of 48.81 × 109ohm cm. Meanwhile, the addition of 1-5% NCC showed the highest value was obtained by the addition of 3% NCC with Young's modulus of 1090.60 MPa and Volume resistivity of 4.278 × 109ohm.
