摘要

采用呋喃封端的聚氨酯预聚体与双马来酰亚胺反应，合成了基于Diels-Alder(DA)反应的热可逆自修复聚氨酯(PU-DA).利用FTIR、DSC和gel-solution-gel方法对其分子结构、热性能及其可逆性进行了表征，结果表明，具有热可逆性的DA键被成功引入到聚氨酯中，从而赋予聚氨酯具有良好的再加工性能和自修复性能.通过偏光显微镜观测对材料的自修复行为进行了考察，结果表明，由于DA反应的热可逆性，0.5 mm深度划痕的聚氨酯试样在120℃热处理300 s或130℃热处理150 s后划痕便可消失，从而实现了划痕的自修复.并且模拟实际生活中聚合物材料受到轻微损伤时的情况，通过拉伸试验对0.5 mm深度划痕有效自修复的热处理温度和时间进行了确定，并对同一受损部位多次刻划-修复的修复效率进行了详细研究，结果表明：在120℃处理15 min可达到最佳修复效果，其一次修复效率可达71%，同一受损部位经过3次刻划—修复后，其修复效率仍能达到35%.

Abstract

A new kind of self-healing polyurethane (PU) based on Diels-Alder (DA) reaction (PU-DA) was synthesized

via

the reaction between furan-terminated prepolymer and bismaleimide.The structure

thermal property

and thermal reversibility of the resultant PU-DA were characterized by FTIR

DSC

and gel-solution-gel method.Results showed that the thermally reversible DA bonds were introduced into the polyurethane successfully.Consequently

the polyurethane got the excellent reprocessability and self-healing performance.The self-healing behavior of the PU-DA was investigated by polarized optical microscope

and results revealed that cracks with 0.5 mm in depth in the self-healing polyurethane films could be remended at 120℃ for 300 s or 130℃ for 150 s grounded on the thermal reversibility of DA bonds.Then the slight damage situation of polymer materials in the real life was simulated

and the thermal treatment temperature and time for the effective self-healing of cracks with 0.5 mm in depth were determined by the tensile test.Meanwhile

the healing efficiency of the same damage site in PU-DA film that was cut-healed for 1-3 times was investigated.Results showed that the optimal thermal treatment temperature and time for effective self-healing of cracks were 120℃ and 15 min

respectively.More importantly

the healing efficiency for once cut-healed was as much as 71%

while the healing efficiency could still reach 35% when the self-healing polyurethane was cut-healed at the same site for three times.
