研究了聚丙烯酸（PAA）/多环芳烃（PAH）互穿聚合物（CoPEC）固有的室温修复和自修复性能。在PAA/PAH复合物的超浓缩后，获得了坚韧的弹性材料，其经历由盐促进的自愈合。在中等盐浓度下，CoPEC保持足够弹性以恢复其原始形状，而链是移动的以修复切口，从而导致实际的自愈合行为。
The inherent room temperature mending and self-healing properties of saloplastic PAA/PAH CoPECs are studied. After ultracentrifugation of PAA/PAH polyelectrolyte complexes, tough, elastic materials are obtained that undergo self-healing facilitated by salt. At intermediate salt concentrations the CoPECs remain elastic enough to recover their original shape while the chains are mobile enough to repair the cut, thus leading to actual self-healing behavior.
