Formic acid electrospun composite fibers based on polyhydroxybutyrate/polyamide 6 loaded with protonated montmorillonite as promising disposable heavy metal removal sorbent

The use of electrospinable biodegradable polyhydroxyalkanoate derived from microbial sources and their combination with naturally abundant layered aluminosilicates meet the requirements for the development of new sustainable and biodegradable heavy metal ions removal fibrous sorbent materials. In the present study, novel formic acid electrospun composite biodegradable polymeric fibers based on poly β-hydroxybutyrate/polyamide 6 (PHB/PA6), loaded with protonated montmorillonite (MMT-H) at 10 and 20 wt.
