Definitions

  • FIGS. 7A-7D illustrate a molecular mechanism of light-induced SME of a grafted polymer network: the photosensitive groups (open triangles) of FIG. 7A are covalently linked to the permanent polymer network (filled circles, permanent crosslinks) after stretching and photofixing forming photoreversible crosslinks (filled diamonds) as shown in FIG. 7B ; fixation shown in FIG. 7C and recovery shown in FIG. 7D of the temporary shape are realized by UV light irradiation of suitable wavelengths.
  • the agent may be a salt capable of producing an exothermic reaction when dissolved in water.
  • the agent may be selected from lithium chloride, magnesium chloride, potassium carbonate, magnesium sulfate, calcium sulfate, calcium chloride, calcium oxide, aluminum chloride, aluminum sulfate, potassium aluminum sulfate, and a combination thereof.
  • FIGS. 8A-8C illustrate the molecular architecture of a thermally induced shape memory polymer in which the switching segments are initially relaxed ( FIG. 8A ) and become elongated and fixed when the polymer is cooled ( FIG. 8B ).
  • switching segments are the functional groups or stimuli-sensitive domains that facilitate shape change. When heated, the shape memory polymer reverts back to its original shape ( FIG. 8C ), and the switching segments become relaxed once more.
  • R r ⁇ ( N ) ⁇ m - ⁇ p ⁇ ( N ) ⁇ m - ⁇ p ⁇ ( N - 1 ) ,
  • a pasta dish is disposed in a dual layered plastic tray having a shape memory polymer composed of cross-linked polyethylene and polyethylene/nylon-6 graft copolymer disposed between the two plastic layers.
  • a hydrophilic matrix composed of hydroxypropylcellulose is disposed on the layer above the shape memory polymer and calcium sulfate, lemongrass fragrance, and pressurized carbon dioxide capsules disposed beneath the shape memory polymer.
  • the shape memory polymer undergoes a shape change to a temporary shape and the calcium sulfate is released into the hydrophilic matrix.
  • the exothermic reaction of the calcium sulfate and hydroxycellulose is expected to maintain a warm temperature for the food.
  • the burst release also releases a lemongrass fragrance, and popping (crackling) noises due to the release of the pressurized carbon dioxide capsules in order to contribute a pleasant sensory experience for the consumer.
