Novel polyvinyl chloride composite via hybrid metal-organic framework grafted polyethyleneimine and layered double hydroxide incorporation: Thermal, rheological, and electrical properties
Improving the heat stabilization of polyvinyl chloride (PVC) is of great importance, particularly for its use in electrical insulation. In this study, a novel zeolitic imidazole framework (ZIF-8) was modified using polyethyleneimine (PEI) and layered double hydroxide (LDH) to create a new PVC heat s...

| description | Improving the heat stabilization of polyvinyl chloride (PVC) is of great importance, particularly for its use in electrical insulation. In this study, a novel zeolitic imidazole framework (ZIF-8) was modified using polyethyleneimine (PEI) and layered double hydroxide (LDH) to create a new PVC heat stabilizer. The heat stability of PVC was analyzed using oven, Congo red, and thermogravimetric analysis (TGA) tests, with the dosage of modified ZIF-8 found to have a significant impact on PVC's heat stability (increasing from 33 to 58 min). Additionally, con-calorimetry was performed to evaluate the effect of LDH modification on ZIF-8′s flame retardancy, revealing that LDH delayed flame emission from 255 to 560 s. Lastly, volume resistance and mechanical tests were conducted to assess the effect of the novel ZIF-8 modification on PVC compound properties. |
