“…To enhance starch film properties like mechanical properties, water absorption behaviour, and in vitro degradation of the films, nano-cellulose is added to the starch. Depending on the results, nano-cellulose leads to the improvement of the mechanical properties of starch by up to 70% [ 14 ].…”

“…While those changes were less prominent in the case of films composted under nontreated conditions after 10 days, PVA/TPS films tested under preheated and bioaugmented conditions were highly disintegrated, and a lot of cracks and holes appeared on the surface. Observation of SEM images for the degraded samples clearly showed disintegration across entire films on the surface, indicated by a plethora of small crumbled/fractured parts, although the material Pure PVA films appeared to have a planar, smooth surface and seemed to only possess visible agglomerates and granules after blending with starch [55]. Images of the control PVA/TPS film in Figure 8 indicated quite a smooth and planar surface morphology, with no visible signs of starch particles.…”

“…In order to gain an insight into the changes in morphology caused by the activity of enzymes presented in different composting systems, SEM analysis was also carried out and the recorded images of the PVA/TPS films before and after degradation are shown in Figure 8. Pure PVA films appeared to have a planar, smooth surface and seemed to only possess visible agglomerates and granules after blending with starch [55]. Images of the control PVA/TPS film in Figure 8 indicated quite a smooth and planar surface morphology, with no visible signs of starch particles.…”

“…18 The tensile strength of starch/PVA composites prepared by Aanchal Mittal et al using urea and formaldehyde as a composite crosslinking agent increased by 71%. 19,20 The tensile strength, elongation at break and water resistance of the starch/PVA films prepared by Hu et al using lactic acid were greatly improved. 21 Starch molecular chains have many hydroxyl groups, which easily form intermolecular and intramolecular hydrogen bonds, which leads to the brittleness of the pure starch/PVA composite film.…”
