Citronellol-derived methacrylate polymers with four side
chain
interconnecting groups of different polarities (PCHM-Xs) are synthesized
to prepare bio-based bactericidal polymers. The PCHM-X bactericidal
activities are significantly affected by the different functional
groups determining the interaction between the polymer chain and bacterial
membrane that disrupts the membrane integrity causing cytoplasmic
leakage, the main contributor to the polymer antibacterial properties.
PCHM-SO, with a large dipole moment and strong hydrogen bonding ability,
shows the best bactericidal activity among PCHM-Xs due to the strongest
interactions with the bacterial membrane components. A sulfoxide-group-containing
polymer with excellent bactericidal activity (99.99%) and the systematic
study of the effect of different functional groups on the bactericidal
activity are first reported herein.
A cathode-coating material composed of cationic polymer-grafted graphene oxide (CPGO) and carbon nanotube (CNT) was prepared and used as a cathode-coating material for lithium sulfur batteries.
