Abstract: Polyisocyanates can not only crosslink polymers, but also help to keep them intact. Studies of the self-recovery behavior of aliphatic polyurethane systems after scratching provided the starting point for analysis of energy-specific recovery index. This article described the self-healing capability of pethane systems, which consequently provides the polymer shape-memory effect.

Key words: self healing, scratch resistance, polyurethane

摘要： 多异氰酸酯不仅具有交联聚合物的作用,还能保持聚合物的完整形态。本文对被刮擦过的脂肪族聚氨酯体系的自我修复行为的研究为能量具体修复指数提供了起点,描述了聚氨酯体系的自我修复功能,而使聚合物体系具有形态记忆效应。
