Polylactic Acid-Based Film Modified with Nano-Ag-Graphene-TiO₂: New Film versus Recycled Film

Table 1

Images and elemental composition of the new and recycled nano-Ag-graphene-TiO₂-PLA films.

C (wt%)	52 ± 5^a	58 ± 1^a	60 ± 1^a
O (wt%)	47 ± 4^a	42 ± 2^a	40 ± 1^a
Ti (wt%)	0.2 ± 0.01^a	0.11 ± 0.01^a	–
Ag (wt%)	0.1 ± 0.01 ^a	0.1 ± 0.01^a	–

In each line, mean values with superscript letter (^a) are statistical nonsignificant different at (one-way ANOVA—Tukey’s test).
