Described herein is a crosslinked graphene and biopolymer (e.g. lignin) based composite membrane that provides selective resistance for solutes while providing water permeability. The membrane may include optional additional functional additives in a crosslinked material matrix that provides enhanced salt separation from water. Methods for making such membranes, and methods of using the membranes for dehydrating or removing solutes from water are also described.

Selectively permeable graphene oxide membrane

Described herein is a graphene material such as graphene oxide and polymer based selectively permeable element that provides selective permeability between polar and non-polar molecules such as fluid, gas or vapor. The methods for making these selectively permeable elements and related devices are also described.

Selectively permeable graphene oxide element

Described herein is a graphene-based valve element capable of passive and repeatable stopping or allowing fluid flow as a function of inlet pressure. Passive flow controller devices based on the valve element are also described.

Pressure sensitive graphene-based valve element

Described herein is a graphene material based membrane that provides selective resistance for solutes or gas while providing water permeability. A selectively permeable membrane comprising graphene oxide, reduced graphene oxide, and also functionalized or crosslinked between the graphene, that provides enhanced salt separation from water or gas permeability resistance, methods for making such membranes, and methods of using the membranes for dehydrating or removing solutes from water are also described.

A photorefractive device () and method of manufacture are disclosed. The device () comprises a layered structure in which one or more polymer layers () are interposed between a photorefractive material () and at least one transparent electrode layer (). The layered structure is further interposed between a plurality of substrates (). When a bias is applied to the device (), the device () exhibits an increase in signal efficiency of approximately three to four times that of similar, but non-buffered, devices. Concurrently, the device () of the present disclosure utilizes approximately half the biased voltage, advantageously resulting in a longer device lifetime.
