Investigation of thermal, mechanical and electrochemical properties of nanocomposites based on CuO modified poly(vinyl chloride)/poly(methyl methacrylate) blend

Abstract

The preparation of binary polymer blend nanocomposites with different nanomaterials is a relatively new approach to achieve desired physical, thermal, mechanical, and electrochemical properties because it has the collective effects of both polymer blending and fillers. Transition metal oxides constitute a large class among those fillers because the precursors for metal oxides are abundantly available. However, very few studies have been accomplished on incorporating transition metal oxides into binary polymer blends. In this project, cuprous oxide (CuO) nanoparticles (NPs) with a crystallite size of 24.95 nm were incorporated into poly(vinyl chloride)/poly(methyl methacrylate) (PVC/PMMA) blend, and thin films of the nanocomposites were obtained through a solution casting technique. Scanning electron microscopy, X‐ray diffraction, universal testing machine testing, thermogravimetric analysis, and cyclic voltammetry were used to study morphological, crystalline, mechanical, thermal, and electrochemical properties of the nanocomposites. Scanning electron micrographs showed that the blend was completely miscible and CuO NPs were well dispersed within the matrix. Mechanical properties greatly improved with each wt% addition of CuO NPs. Thermogravimetric analysis thermograms revealed a two‐stage degradation for neat PVC/PMMA blend and CuO/PVC/PMMA. Cyclic voltammetry results indicated a free electron transfer in neat blend that further improved with the incorporation of increasing percentage of CuO NPs. J. VINYL ADDIT.

Performance Evaluation of Mixing Mechanism and its Effects on Thermal Behaviour of Plasticised PVC

“…PVC has low heat of combustion and it is an essential characteristic that gives it a preference over other plastics when flammability resistance is the basic choice for an appropriate application. The total heat emitted during combustion and the rate of this heat is one of the most important factors that control the actual spread of flame, which determines how can the materials fighting the fires [7][8][9][10][11][12].…”

Application of CuO nanoparticles modified with vitamin B1 for the production of poly(vinyl alcohol)/CuO nanocomposite films with enhanced optical, thermal and mechanical properties

“…It displays that the tensile strength and elongation decrease by adding CuO NPs into the PVA matrix (Table ). This behavior is justified with the strong interfacial interaction between the nano‐fillers and the polymer matrix . Therefore, inorganic nano‐fillers have been applied in the plastic industry to improve the mechanical behaviors of thermoplastics.…”

Enhancing the microstructural, optical, and tensile properties of the PVC‐PMMA blend film: The role of PbO nanoparticles incorporation

“…Firstly, it should be mentioned that the tensile test is considered an efficient and heavily used mechanical test in the case of polymeric systems. [61][62][63][64] This test helps in finding important parameters. From surveying the literature, it was found that the tensile properties of blend and PNC films depend on: (i) The dispersion of nanofillers.…”
