Abstract
ABSTRACT This study introduces an innovative utilizing polybutylene succinate (PBS) and polyvinyl alcohol (PVA) for seedling bags, enriched with glycerol (G) and calcium hydrogen phosphate (CaHPO4) fertilizer. The investigation examined the impact of PVA (10–50 wt.%) with fixed glycerol ratio of 20 phr, and CaHPO4 content (0–7 phr) on the composite. Notably, higher PVA content led to better dispersion of PVA particles within the PBS/G blend, reducing phase separation compared to lower PVA content. However, increased PVA content resulted in decreased mechanical properties due to incompatibility and phase separation, as well as interference with PBS crystallization. Regarding CaHPO4, the addition of a low fertilizer amount (3 phr) slightly reduced crystallinity (from 40% to 19%) but increased elongation at break (from 2.7% to 3.8%). Conversely, higher CaHPO4 content (5–7 phr) significantly enhanced tensile strength and elongation at break to 5.6 MPa and 6.3%, respectively, without affecting crystallinity. Importantly, CaHPO4 incorporation improved the dispersion of PVA within the PBS matrix. In practical application, PBS/PVA/G/CaHPO4 composites proved suitable for planting seedlings, which thrived in the bags over 42 days. This study underscores the potential of these composite materials for seedling cultivation, while future research may delve into optimizing fertilizer effectiveness in this context.
