Abstract:
This study used two adsorptive hydroxyapatite nanorods (HAPR) and hydroxyapatite nanowires (HAPW) as modifiers. HAPR and HAPW with different aspect ratios have different abilities to induce axial alignment of adjacent Poly (vinyl alcohol) (PVA) molecular chains as nucleation sites. Thus, they can regulate the comprehensive properties of the two composite films. Tensile curves show that the properties of the two composite films are optimal when the PVA/HAPR ratio is 25% and the PVA/HAPW ratio is 10%. Compared with pure PVA films, they are improved by 2.17 times and 1.62 times, respectively. In addition, the optimized PVA/HAPW composite film has an adsorption capacity of 26.2 g/g for 1-Pentanol. This is due to the microporous structure and surface groups constructed by HAPW. This study provides a new research idea for the preparation of PVA/HAPR and PVA/HAPW composite films with simple processes. It has potential scalability in the direction of achievable industrial oil-water separation materials.
