Abstract
Polyvinylidene chloride (PVDC) resin modified with γ-methylacryloxy propyl trimethoxysilane (KH570) and acrylamide (AM) was prepared by semi-continuous seed emulsion polymerization. The polymerization process and reaction temperature were optimized through conversion rate and oven heat aging test. Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) analysis showed that KH570 and AM could be successfully grafted into the PVDC resin chain. When the addition amounts of KH570 and AM are 1 wt.% and 1.5 wt.%, respectively, and the reaction temperature is 74 °C, the resin film exhibits significant improvement in yellowing resistance and mechanical properties. The initial yellowing time of the resin film modified by KH570 and AM was 290 min, which was 5.8 times of the unmodified resin film, and the tensile strength can reach 10.81 MPa, which is 1.75 times of the unmodified resin film. Because the modified resin has good thermal yellowing and mechanical properties, it has potential application prospects in food and drug packaging.
期刊介绍:
Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field.
The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest.
Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials.
Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
