| Summary: | We conducted a systematic experimental investigation to characterize the shape-memory effect in a commercial poly(ether ether ketone) (PEEK), which is a very important high-temperature polymers at present. The focus was on the influence of the programming conditions and heating temperature for recovery on the shape-recovery ratio (Rr). We concluded that PEEK is not only an important engineering polymer as it is traditionally known but is also an excellent high-temperature shape-memory polymer. For a residual programming strain of 30%, the maximum Rr was about 90%. It was revealed that it was practically feasible to program PEEK at room temperature and to lower the recovery temperature from its melting temperature range to around its glass-transition temperature. |
