The photocatalytic degradation of linear low density polyethylene (LLDPE) using CaO nanoparticles was carried out using 500 Watt lamp. After degradation of LLDPE, morphology, crystallinity as well as thermal properties of the specimen was investigated by scanning electron microscopy (SEM), X-ray diffraction (XRD) and differential scanning calorimetry (DSC). SEM results, before and after photodegradation, showed the LLDPE to be much more prone to cracking into small snippet, which indicated a rise in crystallinity with different amount of CaO nanoparticles. The DSC result confirmed the remarkable influence of photodegradation on degree of crystallinity (XC %), fusion enthalpy (ΔΗ Jg−1) and melting temperature (Tm) of LLDPE. Infrared spectrometry (FTIR) has demonstrated different functional groups obtained after chain scission. The comparison of FTIR before and after photodegradation confirmed fragmentation of the polymer chain. Results showed that LLDPE was degraded successfully by using CaO nanoparticles under visible light exposure.
