And Chemical Properties

The necessity of using petrochemicals for the development of polymers has been deteriorating because of the depletion in fossil fuels and environmental concerns such as the effect of greenhouse gases, global warming, and increasing population. Research has shown a shift from petroleum-based fuels to plant oil–based fuels in order to shift to renewable resources. Natural oils such as castor oil have shown competitive physical and chemical properties as compared to fossil fuels. The use of natural oils has gained a lot of research interest due to the fact that they are renewable, affordable, and environmentally friendly. Bio-oils are versatile because they have various derivatives and can be used in different grades based on the application in various industries such as agriculture, food, paper, and electronics. Bio-binders have been considered as the most promising materials for the different applications. In this review, the processes of chemical modifications of castor oil are discussed.

Sugar esters are bioactive compounds derived from renewable resources. They consist of a sugar moiety with attached non-polar part – usually a fatty acid. These compounds find uses in cosmetic, food and pharmaceutical industries as surfactants due to their physicochemical and antimicrobial activities. In this study we have produced fatty acids for sugar ester synthesis from bacterially derived polyesters, namely polyhydroxyalkanoates (PHAs). We have developed methodology to decorate PHA monomers with a fluorinated moiety. With aid of biocatalysis a series of glucose esters was created with unmodified and modified PHA monomers. All synthesised compounds showed moderate antimicrobial activity.

AbstractThe drive for greater use of renewable materials is one that has recently gained momentum due to the need to rely less heavily on petroleum. These renewable materials are defined as such since they are derived from plant-based sources. Some renewable materials also offer properties that conventional materials cannot provide: hierarchical structure, environmental compatibility, low thermal expansion, and the ability to be modified chemically to suit custom-made applications. Nature's materials, particularly from plant- and animal-based polysaccharides and proteins, have hierarchical structures, and these structures can be utilized for conventional applications via biomimetic approaches. This issue begins with an article covering renewable polymers or plastics that can be used to generate block copolymers (where two polymers with specific functions are combined) as an alternative to conventional materials. Applications of renewable polymers, such as cellulose from plants, bacteria, and animal sources, are also covered. Also presented are the use of bacterial cellulose and other plant-based nanofibers for transparent electronic display screens and, in a wider sense, the use of cellulose nanofibers for composite materials, where renewable resources are required to generate larger amounts of material. Finally, this issue shows the use of biomimetic approaches to take the multifunctional properties of renewable materials and use these concepts, or the materials themselves, in conventional materials applications.
