Figure 8.1Influence of TEC (a) and ATBC (b) on glass transition temperature of PLA ref. [5].
Chenet al. [6] studied the effect of four different ionic liquids:
1-methyl-3-pentylimidazolium tetrafluoroborate ([MPI][BF 4 ]),
1-methyl-3-pentylimidazolium hexafluorophosphate ([MPI][PF 6 ]),
1-methyl-3-pentylimidazolium bis(trifluoromethanesulfonyl)imide ([MPI][TFSI]),
1,2-dimethyl-3-pentyl imidazolium bis(trifluoromethanesulfonyl)imide ([DMPI][TFSI]).
Their main results are reported in Tables 8.4 and 8.5 and Figure 8.2.
