Shape memory plastic
WebbShape memory alloys are a unique class of alloys that have ability to ‘remember’ their shape and are able to return to that shape even after being bent. At a low temperature, a SMA can be seemingly plastically deformed, but this ‘plastic’ strain can be recovered by increasing the temperature. This is called the shape memory effect (SME). Webb18 sep. 2015 · The sample with lower Mn of 22.1 kg/mol ( Mw = 37.6 kg/mol) shows a rather low shape fixity of 65% when the applied temperature is Tg + 20 °C and the shape …
