“…These will be applied as antibacterial materials, 9,10 protein drugs and DNA carriers, [22][23][24] flocculants, 25 battery membranes, 26 and antioxidants, 27 among other applications. Furthermore, 2 0 -O-HTACCt will probably be endowed with considerable cellular compatibility due to the retained acetamido groups.…”

“…Due to the presence of -NH 2 and -OH groups on the polymer backbone, CS can be chemically modified, which is beneficial to the fuel cell performances [22,23]. However, since there are no mobile hydroxyl ions in its structure, the pristine CS membrane shows much lower ionic conductivity [24]. On the other hand, the quaternized polymers have been mostly investigated as AEMs for fuel cell; however, the materials using alkyl quaternary ammonium groups as anion exchange groups are verified to be unstable in alkaline medium, especially at elevated temperatures [25].…”

“…A literatura reporta outros estudos sobre membranas de QTS trocadoras de prótons. 13,14 Para um bom funcionamento da célula a combustível utilizando membranas de QTS, faz-se necessário modificar a composição e/ou adicionar outros materiais, por exemplo, plastificantes e/ou reticulantes, preparar membranas de polímero/polímero ou polímero/material inorgânico. Estas últimas são interessantes devido à contribuição para o aumento da condutividade protônica, manutenção de água em altas temperaturas e, maior sustentação mecânica.…”
