Abstract
Poly(butylene adipate-co-terephthalate), PBAT, is a synthetic and 100% biodegradable polymer based on fossil resources, with high elongation at break and high flexibility. These properties are comparable to lowdensity polyethylene, making PBAT a very promising biodegradable material that could replace it in some industrial applications. However, its lower mechanical properties have limited its application range. The reinforcement of PBAT with rigid filler, such as zein-TiO2 (ZTC) complex microparticles, has the purpose to expand its application fields, from the food and agricultural packaging to healthcare sector. The 3D printability of bio-based composites was demonstrated by realizing complex structures with a commercial FDM printer.File | Dimensione | Formato | |
