7.4.3 MECHANICAL PROPERTIES OF TIO2/CELLULOSE/SPI BLEND FILM Mechanical properties of SPI films incorporated cellulose and/or TiO 2 were obtained for RH of 43, 58 and 84% (Table 7.2). Figure 7.7 displays the tensile properties between all treatments. Similar to previous results, increasing RH translated to a decrease in tensile strength. For SPI/TiO2 and SPI/fiber blend films, results were also similar to previous findings where the optimal concentration for maximum strength was near 0.25% w/w. However, when 0.25% w/w of TiO2 was used as a coupling agent, the optimal loading of cellulose fiber shifted to 1% w/w. A positive correlation between tensile strength and TiO 2-coupled fiber concentration was seen across all levels of RH. At 84% RH, the tensile strength of TiF1.0 is clearly improved over Ti1.0 and F1.0 showing a synergistic effect. The positive trend suggests that cellulose incorporation beyond 1% w/w may further increase material strength and promote higher cellulose utilization. 101
