![]() Just how many different functions can you design into a single room? Lots, if you're using memory plastic.
Compare to the plastex from J.G. Ballard's 1962 story The Thousand Dreams of Stella Vista.
This kind of material is starting to make headlines almost forty years after Niven wrote about the idea; I don't know if this is an original idea of Niven's or whether the idea was in the air in the late 1960's.
The new materials, known as "triple-shape materials," can assume three different shapes, each shape depending on how much heat is applied.
This landmark achievement comes from the laboratories of chemical engineer Robert Langer of MIT and polymer chemist Andreas Lendlein of the Helmholtz Institute in Teltow, Germany.
![]() "The series above illustrates the triple shape effect of a fastener consisting of a plate with two anchors prepared from CL(50)EG: Starting at 20 degrees Celsius, the device, in an easily-handled form, is put into a scaffold, right, which might be difficult to access (a). Increasing the temperature to 40 C triggers unfolding and positioning into the cavity, left (figures b to d). Increasing the temperature to 60 C enables the anchors of the fastener to open and to couple the device into a well-defined position (e to f). In both series, above and left, the material CL(50)EG used to produce the demonstration object is a two-phase polymer network consisting of 50 percent poly(ethylene glycol) (PEG) by weight and 50 percent poly(e-caprolactone) (PCL) by weight.
