Published: April 5, 2024

Significant interest is devoted to the development of new polymer blends by using concepts circular economy. Such materials have predetermined properties, are easy recycle, ecological, and a low carbon footprint. This research presents obtaining characterization based on low-density polyethylene (LDPE) thermoplastic starch (TPS). In first stage, TPS was obtained through gelatinization process, and, in second mixtures LDPE were melt mixing process at 150 °C for 7 min. The physical–mechanical characteristics samples, like hardness, elongation break, rebound resilience, tensile strength, determined. sample containing maleic anhydride grafted (LDPE-g-MA) as compatibilizer shows improvements break strength (by 6.59% 40.47%, respectively) compared test sample. FTIR microscopy maps show that samples LDPE-g-MA more homogeneous. SEM micrographs indicate TPS-s homogeneously dispersed droplets matrix. From thermal analysis, it observed both degree crystallinity mass loss high temperature influenced composition samples. flow index has adequate values, indicating good processability specific methods (such extrusion or injection).

Gelatine Blends Modified with Polysaccharides: A Potential Alternative to Non-Degradable Plastics

International Journal of Molecular Sciences, Journal Year: 2024, Volume and Issue: 25(8), P. 4333 - 4333

Published: April 14, 2024

Non-degradable plastics of petrochemical origin are a contemporary problem society. Due to the large amount plastic waste, there problems with their disposal or storage, where most common types waste disposable tableware, bags, packaging, bottles, and containers, not all them can be recycled. growing ecological awareness, interest in topics biodegradable materials suitable for items has begun reduce consumption non-degradable plastics. An example such biopolymers derivatives, which used create so-called bioplastics biopolymer blends. In this article, gelatine blends modified polysaccharides (e.g., agarose carrageenan) were created tested order obtain stable coating. Various techniques characterize resulting bioplastics, including Fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA)/differential scanning calorimetry (DSC), contact angle measurements, surface energy characterization. The influence thermal microbiological degradation on properties was also investigated. From analysis, it observed that addition increased hardness mixture by 27% compared control sample without polysaccharides. addition, an increase (24%), softening point (15%), glass transition temperature (14%) sample. starch matrix 15% 6%. After aging, both compounds showed 26% decrease tensile strength 60%. This offers opportunity as application form coatings, dietary supplements, skin care products, short-term single-contact decorative elements, food, medical, floriculture, industries.
