A preparation method of thermadapt shape memory polymers includes: (1) synthesis of pendant hydroxyl groups functionalized epoxy oligomer using epoxy resin and alcohol amine; (2) synthesis of alkoxyl groups terminated silane crosslinking agent by isocyanate silane coupling agent and diamine; (3) crosslinked shape memory polymers were prepared by condensation reaction of pendant hydroxyl groups functionalized epoxy oligomer and alkoxyl groups terminated silane crosslinking agent. The thermadapt shape memory polymers show high glass transition temperatures and high tensile strength. The original shape of thermadapt shape memory polymers can be reconfigured to a new permanent shape as needed, and thus effectively solving the bottleneck problems of reprocessing or reshape in the traditional crosslinked polymers once after molding. The thermadapt shape memory polymers are suitable for smart materials based on shape memory polymers with complex three-dimensional permanent shapes, and showing unfolding or folding behaviors along with convert to three-dimensional structures under heat stimulation.

Adaptive smart textiles that facilitate reduced energy consumption are described. In one implementation, a dual pane fabric arrangement includes a first pane of fabric and a second pane of fabric separated by an intra-layer gap, and an insert layer disposed in the intra-layer gap, wherein the insert layer causes a thickness of the intra-layer gap to change responsive to changes in ambient temperature.

A wrap-around heat shrinkable protective jacket is used on conduits such as cables, pipes or tubes carrying liquids, gas or electricity to name a few. The protective jacket is applicable to junction blocks, junction tees and wire harnesses and to protect or repair damaged areas of such configurations. A lay-flat design is used to easily install around existing cables, pipes or tubes. A shrinkable material is used to secure and protect these cables, pipes or tubes. Other materials can be added to the jacket interior for additional protection.
