摘要:

在經(jīng)歷了大“塑性”變形后，通過施加某種特定激勵(lì)（如變溫、浸泡化學(xué)溶劑、試劑、光照等），材料能夠恢復(fù)到原來的形狀。具有這種形狀記憶效應(yīng)功能的材料被稱為形狀記憶材料。一系列試驗(yàn)表明， 聚合物材料大都具有熱驅(qū)動(dòng)和化學(xué)驅(qū)動(dòng)的形狀記憶效應(yīng)。最近的研究更證實(shí)了：依據(jù)多種基本原理，人們不僅可以通過修改已有的材料（如各種工程塑料），來設(shè)計(jì)新材料，并且可以優(yōu)化材料，使之具有我們需要的形狀記憶功能去滿足工程應(yīng)用的要求。因此，此種技術(shù)可以被稱為高級(jí)形狀記憶技術(shù)，以區(qū)別過去只局限于某些特定材料的形狀記憶及其技術(shù)。高級(jí)形狀記憶技術(shù)可以為產(chǎn)品從設(shè)計(jì)、制造到最終再循環(huán)提供不同于傳統(tǒng)方法的思路。著重介紹了這一方面的最新進(jìn)展。

Abstract:

After being severely and quasi�瞤lastically deformed, upon applying a particular stimulus, some materials are able to recover their original shape. Such a phenomenon is known as the shape memory effect (SME) and materials with this feature are called shape memory material (SMM).Recent experiments reveal that heating��/ chemo�瞨esponsive SMEs are almost intrinsic features of polymers. Further investigation confirms that based on various basic mechanisms, we are able to not only enable the SME in currently used materials, but also design a new SMM and further more optimize their performance. Hence, this technology may be termed advanced shape memory technology (ASMT), in order to distinguish it from the previous definition, which is limited to some particular SMMs. ASMT is able to reshape product design, fabrication and even recycling. This paper aims to review recent development in this area.
