德国科学家Andreas Lendlein等研制出一种新的光致形变高分子材料,该材料用紫外光照射时能够发生形变,这种材料比一些医学上及其他应用上的热致形变材料性能更优越。其关键技术是分子开关-接枝到共聚物骨架上的光响应基团。当这种共聚物膜铺展开并利用紫外光照射时,其分子就会?
German scientist Andreas Lendlein developed a new type of photo-deformable polymer material that can be deformed by irradiation with UV light. This material is superior to some thermotropic materials used in medicine and other applications. The key technology is the molecular switch - the light-responsive group grafted onto the copolymer backbone. When this copolymer membrane spread and use ultraviolet light, its molecules will?
