Abstract
Maleated cassava starch (MCS)/poly (vinyl alcohol) (PVA)/kaolin clay (KC) nanocomposite films with high mechanical and barrier properties were prepared by a simple casting film. Based on the MCS/PVA matrix, the effects of KC content on the MCS/PVA/KC nanocomposite films were investigated. SEM results demonstrated that the MCS/PVA/KC nanocomposite films exhibited KC good dispersion in the polymer matrix. FTIR spectra showed that the molecular interactions in the MCS/PVA/KC films with higher PVA content enhanced. The maximum tensile strength and elongation at break for the MCS/PVA/KC at 6 and 5% KC composite films were 16 MPa and 530%, respectively. The MCS/PVA/KC composite was applied to extend the shelf life of the banana, and results showed that the good shelf life of the banana was accepted. The MCS/PVA/KC composite film is a promising material for high-barrier food packaging.
期刊介绍：
"Polymer Bulletin" is a comprehensive academic journal on polymer science founded in 1988. It was founded under the initiative of the late Mr. Wang Baoren, a famous Chinese chemist and educator. This journal is co-sponsored by the Chinese Chemical Society, the Institute of Chemistry, and the Chinese Academy of Sciences and is supervised by the China Association for Science and Technology. It is a core journal and is publicly distributed at home and abroad.
"Polymer Bulletin" is a monthly magazine with multiple columns, including a project application guide, outlook, review, research papers, highlight reviews, polymer education and teaching, information sharing, interviews, polymer science popularization, etc. The journal is included in the CSCD Chinese Science Citation Database. It serves as the source journal for Chinese scientific and technological paper statistics and the source journal of Peking University's "Overview of Chinese Core Journals."
