Graphene composites are disclosed. The graphene composites may include, for example, a photoswitchable layer, a graphene layer, and a substrate. The graphene composites may, in some embodiments, include a graphene layer with photoswitchable surface characteristics. Methods of making the graphene composite are further disclosed. Devices and systems configured to make and use the composites are also disclosed.

Photoswitchable graphene membranes

Inorganic siloxane ladder polymers with metal-aza/thio crown complexes, and methods of making and using such siloxane ladder polymers are disclosed. The polymers described herein may exhibit self-healing properties, a low dielectric constant, and a low refractive index. These siloxane ladder polymers are anchored to transparent, high-refractive index (RI) metal nanoparticles, such as ZrO, via aza/thio crown macromolecules. The siloxane ladder polymers may be considered as 'living polymer network' since the polymer active chain ends may further undergo anionic polymerization.

Fluorinated siloxane compositions, and methods of making and using the fluorinated siloxanes are disclosed. The polymers described herein may exhibit self-healing properties, a low dielectric constant, and a low refractive index. In some embodiments, a method of making a siloxane compound may involve contacting a silicon metal with a fluorinated compound to form a dichlorosilane compound, hydrolyzing the dichlorosilane compound to form a fluorinated tetrasiloxane compound, and contacting the fluorinated tetrasiloxane compound with a metal catalyst to form a fluorinated cyclic siloxane (D4) compound.

Fluorinated siloxanes and methods for their preparation

Techniques described herein generally relate to etching graphene. The techniques can include disposing graphene on a patterned substrate, applying a resist to the graphene on the patterned substrate, curing the resist, and etching exposed portions of the graphene. Graphene composites including patterned substrates, graphene disposed on the patterned substrate, and a resist disposed on the graphene, are disclosed. Systems configured to perform the methods and/or make the graphene composites are also disclosed.

The present disclosure pertains to coatings with self-repairing capabilities. In some embodiments, the coatings may include a polymer blend, made up of at least two polymers. The coatings may further contain compatibilizers that are nanocontainer particles. The nanocontainers may be filled with self-healing agents. The self-healing agents may be agents that heal cracks formed in the coating or they may be anti-corrosion agents that reduce the corrosion of the underlying metal substrate.

A polymeric flexible substrate that meets the barrier requirements for oxygen and water, while exhibiting thermal stability or transparency may be formed from functionalized graphanes bonded with polymers.

Composite films and methods for their production

Technologies are generally described for gas filtration and detection devices. Example devices may include a graphene membrane and a sensing device. The graphene membrane may be perforated with a plurality of discrete pores having a size-selective to enable one or more molecules to pass through the pores. A sensing device may be attached to a supporting permeable substrate and coupled with the graphene membrane. A fluid mixture including two or more molecules may be exposed to the graphene membrane. Molecules having a smaller diameter than the discrete pores may be directed through the graphene pores, and may be detected by the sensing device. Molecules having a larger size than the discrete pores may be prevented from crossing the graphene membrane. The sensing device may be configured to identify a presence of a selected molecule within the mixture without interference from contaminating factors.

The present disclosure generally describes techniques suitable for use in the construction or recycling of composite materials. An article may comprise a thermoplastic coupled to a bonding interface layer, with a coating layer applied to the surface of the bonding interface layer. A bonding interface layer may comprise catalytic nanoparticles embedded within and/or encapsulated by one or more radiatively unstable polymers. Application of ionizing radiation to the article may release a catalyst at the bonding interface. Application of heat and/or stress to the article may enhance catalytic degradation of the remaining bonding interface and uncoupling of the thermoplastic from the coating layer. Embodiments of methods, compositions, articles and/or systems may be disclosed and claimed.
