Main mechanical properties: elastic modulus (E), tensile strength (TS), and elongation at break (EB), of neat PLA and PLA/NaMMt containing different amounts of Q.

Sample	E (MPa)	TS (MPa)	EB (%)
PLA	1555 ± 50	47.0 ± 2.5	9.1 ± 1.5
PLA + 2.5% NaMMt	1845 ± 58	51.2 ± 3.5	9.5 ± 2.0
PLA + 2.5% NaMMt + 0.5%Q	1848 ± 55	43.8 ± 2.1	15.0 ± 2.5
PLA + 2.5% NaMMt + 2%Q	1832 ± 51	42.8 ± 2.2	14.1 ± 2.5
PLA + 2.5% NaMMt + 3%Q	1808 ± 52	40.8 ± 2.5	13.0 ± 2.5
