浙江大学化学工程与生物工程学院的研究人员研发出一种新型形状记忆塑料,能够多次“植入”复杂形状记忆,遇热即可实现形变。形状记忆塑料是一类能够固定临时形状并在外界刺激下恢复到初始形状的智能材料,在柔性电子、生物医学和航空、航天等领域具有广阔的应用前景。研究人员在设计新型形状记忆材料时,加入了一种可交换共价键,重组了分子间的连接关系。这相当于很多分子手拉手 Researchers at Zhejiang University’s School of Chemical Engineering and Bioengineering have developed a new shape memory plastic that can “implant ” complex shape memory, deformation can be achieved when exposed to heat. Shape memory plastic is a kind of smart material that can fix temporary shape and return to its original shape under external stimuli. It has broad application prospects in the fields of flexible electronics, biomedicine, aviation and aerospace. Researchers in the design of a new shape memory material, joined an exchangeable covalent bond, the reorganization of the connection between molecules. This is equivalent to many molecules hand in hand
