Abstract: A thermoplastic interposer formed of ordered polymer sheets that may be configured to act as an interconnect and as a thermal energy spreader. In examples, the thermoplastic interposer may include one or more extensions or wings to further dissipate heat. In examples, laser direct structuring (LDS) may be used to form or more through silicon vias (TSVs) or through-chip vias. In examples, the ordered polymer sheets may be extruded via a roll-to-roll process, stacked, and processed to form a laminate interposer structure that makes up the interposer. In examples, the thermoplastic interposer may be used in multi-layer structures interconnecting two or more board assemblies such as printed circuit boards (PCB)s.

Abstract: A polymer thin film includes polyethylene having a molecular weight of at least approximately 250,000 g/mol, and has an elastic modulus of at least approximately 25 GPa, a tensile strength of at least approximately 0.8 GPa, and a thermal conductivity of at least approximately 5 W/mK. Formation of the polymer thin film may include forming a polymer solution from a crystallizable polyethylene and a liquid solvent, forming a gel from the polymer solution, forming a polymer thin film from the gel by calendering or solid state extrusion, and stretching the polymer thin film.

Abstract: A polymer bilayer includes a layer of a porous fluoropolymer directly overlying a layer of polyethylene. The polyethylene layer may be porous or dense and may include an ultra-high molecular weight polymer. The polymer bilayer may be co-integrated with structures (e.g., wearable devices) exposed to high thermal loads (>0-1000 W/m2) and provide passive cooling thereof. For instance, passive cooling of AR/VR glasses under different solar loads may be achieved by a polymer bilayer that is both highly reflective across solar heating wavelengths and highly emissive in the long-wavelength infrared. The high reflectance decreases energy absorption across the solar spectrum while the high emissivity promotes radiative heat transfer to the surroundings.

Abstract: A light-emitting device includes a light-emitting diode having an emissive surface, and a capping layer including an organic solid crystal overlying the emissive surface. The refractive index of the organic solid crystal may be tuned such as through the application of a voltage, current, or stress to improve the light extraction efficiency of the device.

Abstract: An optically anisotropic polymer thin film includes a crystallizable polymer and an additive configured to interact with the polymer (e.g., via π-π interactions) to facilitate chain alignment and, in some examples, create a higher crystalline content within the polymer thin film. The polymer thin film may be characterized by a bimodal molecular weight distribution where the molecular weight of the additive may be less than approximately 50% of the molecular weight of the crystallizable polymer. Example crystallizable polymers include polyethylene naphthalate, polyethylene terephthalate, polybutylene naphthalate, polybutylene terephthalate, as well as derivatives thereof. Example additives, which may occupy up to approximately 10 wt. % of the polymer thin film, include aromatic ester oligomers, aromatic amide oligomers, and polycyclic aromatic hydrocarbons, for example. The optically anisotropic polymer thin film may be characterized by a refractive index greater than approximately 1.7 and an in-plane birefringence greater than approximately 0.2.
