Microwave synthesis and actuation of shape memory polycaprolactone foams with high speed
Open accessAbstract
Microwave technology is a highly effective approach to fast and uniform heating. This article investigates that the microwave heating as a novel method is used to rapidly foam and actuate biocompatible and biodegradable shape memory crosslinked-polycaprolactone (c-PCL) foams. The optical microscope proves that the resulting c-PCL foams have homogenous pore structure. Mechanical behavior and shape memory performance of c-PCL foams are investigated by static materials testing. Shape recovery ratio is approximately 100% and the whole recovery process takes only 98 s when trigged by microwave. Due to the unique principle of microwave heating, the recovery speed of c-PCL foams in microwave oven is several times faster than that in hot water and electric oven. Hence compared to the traditional heating methods, microwave is expected to bring more advantages to modern industry and scientific research in the field of smart materials and structures.

SMPs are programmable (multi)stimuli-responsive shape-changing polymers and can recover their initial shape upon direct or Joule heating, radiation and laser heating, microwaves, pressure, moisture, solvent or solvent vapors, and changes in pH.
“SMPs also happen to be programmable (multi)stimuli-responsive shape-changing polymers and possess the remarkable property to recover their initial shape upon direct or Joule heating, radiation and laser heating, microwaves [2,3], pressure [4], moisture, solvent or solvent vapors [5] and change in the pH values [6].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
