although drastic changes were not observed, cellulose addition at optimal concentrations would<br />
interact with the surrounding SPI matrix changing material properties.<br />

The WAXD patterns <strong>of</strong> all SPI/cellulose blend films, SPI control and cellulose fibers are<br />
shown in Figure 6.13 and Figure 6.14. Figure 6.13 illustrates WAXD pattern obtained from<br />
unprocessed film specimens, whereas Figure 6.14 illustrates WAXD patterns obtained from<br />
