Two kinds of biobased polymers can be developed. The first one corresponds to macromolecular structures existing in nature as cellulose, lignin, starch, alginate and so-on that most of them are probably the ones that derived from well-established cellulosic industries. Nevertheless, the thermal stability of these rich in oxygen structures are limited, they release relatively little heat during burning and are often able to char. Other biobased polymers are made up of molecules synthesized from natural resources. Not only polymers but also all additives used to modify their properties can be biobased to meet sustainable development. Intensive research is devoted to develop flame retardant biobased polymers from various raw resources. These flame retardant biobased polymers can be used directly as they are, alone or as a component of a more complex system. This is especially true when the molecules are phosphorus-rich as DNA or phytic acid or charring as lignin. All the efforts reviewed in this paper, show that a major objective is to develop 100 % biobased materials suitable for applications requiring high flame retardancy level. Different biomolecules from the cellulosic industry are also the most promising in flame retardancy. Manuscript profile -

What is visible today is referred to exploit the achievements and combine them as new available technologies. To accomplish this gold, we need to develop technologies of 1 to 100 nm to help imagine and sense the interactions between the receptors and specific components. Graphene quantum dots have been developed with easy production methods, biocompatibility, and low toxicity and have been applicable in all fields. This type of quantum dots contains carboxylic acid functional groups on their surfaces, which are interchangeable with other functional groups and have a high solubility in water. It also makes them appropriate for functionalizing with various organic materials such as polymers. Molecular imaging is a fast and accurate method for molecule detection and it is one of the most important methods for molecule detection and quantification. Molecularly imprinted polymer based on graphene quantum dots have being had high-performance applications in most fields of detection and measurement, due to their high selectivity and sensitivity as well as solubility in aqueous media.

Seawater covers two-thirds of the earth's surface, so it makes sense to use these resources to provide drinking water and could be an important component in solving the problem of water scarcity. In addition, existing technologies for water treatment to meet There are certain water quality requirements, so reusing used water to address water shortages can be further explored. In recent years, organic metal frameworks have received much attention due to their interesting chemistry and potential applications. In the science of separation, researchers have extensively studied organic-metal frameworks for gas separation and water treatment. In this paper, the aim is to investigate the possibility of using organic-metal frameworks for membrane desalination. Therefore, after a brief introduction of organic-metallic frameworks, several methods for preparing membranes of organic-metallic frameworks, water desalination techniques and methods of application of organic-metallic frameworks and finally membranes of organic-metallic frameworks for different applications of water Such as desalination, nanofiltration, ultrafiltration and microfiltration are considered. The use of organic-metal frameworks as membranes in water treatment is still in its infancy compared to other applications such as gas separation. Manuscript profile -
