Adel, Nivin M. Ahmed, Amal H. Abdel Kader, Mona K. Al-Shemy, and 1 more This is a preprint; it has not been peer reviewed by a journal. https://doi.org/ 10.21203/rs.3.rs-4696043/v1 This work is licensed under a CC BY 4.0 License Status: Posted Version 1 posted You are reading this latest preprint version Abstract This study focuses on the development of coating films composed of the biodegradable poly (lactic acid) (PLA) combined with metal oxide TiO2/SiO2 core-shell pigments for enhancing the properties of paper sheets used in packaging, besides overcoming the limitations of the individual materials. The objective of this work is to investigate the impact of the different pigment concentrations on the structural, mechanical and barrier properties of the coated paper sheets. Coated papers with biodegradable materials are essential for improving the different properties, such as density, surface gloss, smoothness, and moisture resistance. In addition, core-shell pigments can offer enhanced properties by combining the different properties of more than one component together; such as titanium and silicon oxides, which can provide availability and low cost. The relevant physical and chemical properties for the prepared coating composites and the altered paper sheets were evaluated using XRD, XRF, TEM, SEM, EDX, FTIR, CA and TGA. The findings can contribute to the progress of sustainable and functional packaging materials, highlighting the importance of core-shell pigments in improving their performance.
