| 4 | Description | Abstract | The present paper depicts about the synthesis of cellulose ethyl ammonium thiophosphate (CEASP) and its metal complexes with Cd, Mo and Ce. CEASP and its metal complexes have been characterized by infrared (IR), X-ray diffraction (XRD) and energy dispersive X-ray spectroscopy (EDXS) studies. The surface morphology of samples has been premeditated by means of scanning electron microscopy (SEM). The thermal studies of samples have been carried out at multiple heating rates 2, 5, 10 and 20 o°C min-1 from ambient to 700 oC in nitrogen atmosphere. Non-isothermal model free kinetic methods have been used to calculate activation energy of samples i.e. Friedman, Ozawa-Flynn-Wall (O-F-W) and modified Coats- Redfern. The activation energy of samples lie in range 72-282 kJ mol-1. Thermal study shows that initial degradation temperature of CEASP and its metal complexes decreases and there is abrupt increase in char yield of synthesized samples as compared to pure cellulose. These and other related information suggest that such type of derivatisation could be proved a good flame retardant for cellulose. |
