Among the various sources of bio-based feedstock, vegetable oils are one of the most widely used starting materials in the polymer industry … Biodegradable polymers have been widely used and have greatly promoted the development of biomedical fields because of their biocompatibility and biodegradability. In recent years there has been an increase in interest in biodegradable polymers. The development of biotechnology and medical technology has set higher requirements for biomedical materials. Environmental concerns over waste plastics’ effect on the environment are leading to the creation of biodegradable plastics. So far, various renewable materials, including vegetable oils, polysaccharides, and proteins, have been explored to … Biodegradable Polymer. Because of their specific … synthetic biodegradable polymer s are discussed b elow: 4. Herein, we debated the recent progress in developing biodegradable polymers and their applications.12 billion by 2023, according to the Markets and Markets annual report . Biodegradable Biodegradable materials are used in packaging, agriculture, medicine and other areas. [2] [3] In the field of controlled drug. Because of their specific … • Biodegradable polymers have proven their potential for the development of new, advanced and efficient DDS and capable of delivering a wide range of bioactive materials. The principal forms of polymers used as biomaterials are biologically natural polymers, synthetic biodegradable and nonbiodegradable polymers as shown in Figure 2.stlas cinagroni dna ,ssamoib ,retaw ,)2N ,2OC( sesag sa hcus stcudorpyb larutan ni tluser ot ssecorp noitisopmoced lairetcab yb esoprup dednetni sti retfa nwod skaerb taht remylop fo ssalc laiceps a era sremylop elbadargedoiB. Chitosan is a linear polysaccharide composed of randomly distributed β-linked d-glucosamine and n-acetyl-d-glucosamine.For instance, certain natural polymers play a key role in the maintenance of the structural integrity of cells in plants and animals (e.
