Method for fabricating lightly crosslinked polyimides with phenylethynyl pendants for shape-memory effect and programmed enhancement in Tg and modulus

The invention generally relates to shape memory films that are tri-functionally crosslinked and that comprise multiple, non-terminal, phenylethynyl moieties. In addition, the present invention relates methods of fabricating such films. Due to the improved properties of such SMPS, the SMP designer can program in to the SMP mechanical property enhancements that make the SMP suitable, among other things, for advanced sensors, high temperature actuators, responder matrix materials and heat responsive packaging.

THREE-DIMENSIONALLY PATTERNABLE THERMAL INTERFACE

A three-dimensional geometry of a thermal interface body may be customized to substantially fill an irregular gap along a thermal dissipation pathway in an electronic package. The thermal interface body is fabricated through an additive deposition process, wherein sequential patterns of thermal interface material are coherently connected to other deposited patterns of thermal interface material.

Programmable matter

The devices and systems described herein generally relate to magnetic field chambers and reversibly hardenable ferrofluids. The reversibly hardenable ferrofluid can include a magnetically responsive fluid and a reversible hardening agent. The reversibly hardenable ferrofluid can achieve a first shape using one or more magnetic fields, such as delivered from a magnetic field chamber. Once the first shape is achieved, the reversibly hardenable ferrofluid can be cured or otherwise hardened. The hardened reversibly hardenable ferrofluid can be used for the intended purpose and then returned to a liquid state once the task is completed, allowing for reuse. The steps of hardening and liquifying can be mediated by the magnetic field chamber, as described in embodiments herein.
