The copolymer precursor, poly [4-(4-vinylbenzyl)oxy)phthalonitrile]-co-methyl methacrylate (poly (VBOPN-co-MMA)), was synthesized through copolymerization of VBOPN and MMA at a temperature of 110°C. Subsequently, a single-chain polymer complex of cobalt phthalocyanine (SCP-CoPc) was formed at 150°C by intramolecular macrocyclization between the cobalt and the phthalonitrile group in poly (VBOPN-co-MMA), using excess cyclohexanol. The formation of the SCP-CoPc complex was confirmed through various spectroscopic techniques such as UV/Vis, FT-IR, 1H-NMR, and 13C-NMR. In particular, the disappearance of -CN band at 2232 cm−1 from FT-IR indicated the formation of the SCP-CoPc complex, while the presence of specific absorption bands in the UV/Vis spectrum further confirmed its creation. The electrical, dielectric, optical, and thermal properties of the SCP-CoPc complex and SCP-CoPc/ZnO 5% composites were investigated. The SCP-CoPc/ZnO 5 wt% nanocomposite exhibited improved dielectric and DC conductivity with increasing temperature. The activation energy (Ea) was found to be 0.35 eV for SCP-CoPc and 0.25 eV for SCP-CoPc/ZnO 5 wt% nanocomposite, indicating that the electrical conductivity followed the Arrhenius equation. The optical properties, including band gap, dielectric constant, and refractive index, were calculated for the SCP-CoPc/ZnO 5 wt% nanocomposite. The SCP-CoPc complex possessed a band gap of 2.89 eV, while the SCP-CoPc/ZnO 5 wt% nanocomposite had a slightly reduced band gap of 2.36 eV. The refractive indices of SCP-CoPc and SCP-CoPc/ZnO 5 wt% were also determined.

Waste plastics (e.g., polyethylene, polyvinyl chloride, polypropylene, polystyrene) and petroleum sludge (i.e., main residual from the petroleum industry) pose a severe threat to the environment and human health. These materials are basically nonbiodegradable, and it is difficult to realize the recycling of them and resources via traditional treatment methods. Catalytic pyrolysis as a new recycling treatment method has the characteristics of high efficiency, environmentally benign, no secondary pollution and high product utilization value. This paper mainly reviews the research progress of catalysts used in the catalytic pyrolysis of waste plastics and petroleum sludge. They include molecular sieves, transition metals, metal oxides, clays and activated carbons used for the recycling of plastic, and molecular sieves and M-series catalyst (M=Al, Fe, Ca, Na, K) for treating petroleum sludge. The mechanism of catalytic pyrolysis is also elucidated in this paper. In addition, the challenges faced by catalytic pyrolysis of waste polymers and the future development prospects are also presented.
