Elastic modulus and 1% yield strength from thin films of various PPF:DEF composites. Thin films were tested on an INSTRON mechanical tester and extended at 10 mm/min by a 50 N load cell. n ≥7 for all groups, ANOVA statistical test shows significant difference (p<0.05), and Tukey's post hoc results are shown on graph. Groups that do not share a letter are significantly different.
