Typical light transmittance curves for neat PVA, PVA blends and PVA/ST/GL/HNT nanocomposites as well as respective digital images of Curtin University logo observed through each of film batches were displayed in Figures 3A,B, respectively. Biodegradable starch/poly (vinyl alcohol) film reinforced with titanium dioxide nanoparticles. Moreover, the addition of ST, when considered as a fully biodegradable polymer (Guohua et al., 2006; Azahari et al., 2011), inevitably further increased the biodegradation rate up to 39.54%, which was attributed to easier microorganism attack to ST material structures than those of neat PVA (Hejri et al., 2013, Kale et al., 2007). The incorporation of HNTs to PVA/ST/GL blend films appeared to reduce the Ws in a monotonically decreasing manner from 40.45 to 21.10% with increasing the HNT content from 0 to 5 wt% accordingly. This synthetic polymer, used since the early 1930s, is water-soluble and breaks apart during the wash cycle, releasing the detergent.
