“…VOs are among the most significant renewable materials for polymers because of their widespread availability, natural biodegradability, low cost, minimal ecotoxicity and nontoxicity to humans. [11][12][13][14] The VOs are extracted from seeds or, less often, from other pieces of plants. India is rich in forest resources and has a wide variety of trees that produce a large number of oilseeds.…”

Nowadays, the use of non-edible vegetable oils as the raw material for polymer development is growing in interest because of the scarcity and high demand for crude oil and also because of its eco-friendly approach. The utilization of non-edible oil to synthesize the applicable polymers reduces the usage of petrochemicals. To eliminate the reliance on petrochemicals, it is important to search for and extract alternate and domestic non-edible oils suitable for the synthesis of polymeric materials. This is now a promising research approach. The outstanding feature of indigenous, non-edible Madhuca indica oil (MO) is its chemical structure, with unsaturated sites and esters that are considerable ingredient polyols for the development of polymers. This review discusses the origin, structure and extraction of MO and systematically focuses on the recently developed polymers using oil as a renewable source of polyols. We have briefly reviewed MO-based polymeric materials such as alkyd resins like pentaalkyds for scratch resistance, glycerol alkyds for fly-ash coating, pentalkyd LC resins for display coating applications and epoxies of MO for biological coating materials. Also, the important polyurethanes in the pathways of MO-based fatty amide are transformed into the polyetherimide polyols through a step-growth reaction with bisphenol-A or bisphenol derivatives, which again react with isocyanates to produce MO-based PU for excellent adhesion and coating applications. Another type of waterborne polyurethane is made from polyesteramides. These PU coatings are used in the paint and pigment industries. We reviewed their synthesis and widespread use in coatings and composites.

Fabrication of an appropriate skin scaffold needs to meet several standards related to the mechanical and biological properties. Fully natural/green scaffolds with acceptable biodegradability, biocompatibility, and physiological properties quite often suffer from poor mechanical properties. Therefore, for appropriate skin tissue engineering and to mimic the real functions, we need to use synthetic polymers and/or additives as complements to green polymers. Green nanocomposites (either nanoscale natural macromolecules or biopolymers containing nanoparticles) are a class of scaffolds with acceptable biomedical properties window (drug delivery and cardiac, nerve, bone, cartilage as well as skin tissue engineering), enabling one to achieve the required level of skin regeneration and wound healing. In this review, we have collected, summarized, screened, analyzed, and interpreted the properties of green nanocomposites used in skin tissue engineering and wound dressing. We particularly emphasize the mechanical and biological properties that skin cells need to meet when seeded on the scaffold. In this regard, the latest state of the art studies directed at fabrication of skin tissue and bionanocomposites as well as their mechanistic features are discussed, whereas some unspoken complexities and challenges for future developments are highlighted.

There are ever increasing concerns about environmental and health hazards of conventional synthetic polymers. These polymers are not sustainable because their production process relies on fossil-based feedstocks and energy sources. Economic benefits and beneficial physicochemical and mechanical properties have made synthetic polymers to be used in wide range of applications from packaging to biomedicine. On the other hand, modern chemistry has provided us with invaluable tools to make well-defined polymers with tailored properties which can be used in biomedical filed such as designing advanced drug delivery systems (DDSs). In fact, polymers are indispensable constituents of most of novel DDSs. However, sustainability concerns about raw materials and polymeric building blocks of such DDSs, remains unsolved. In addition, efficient and proper degradability of sustainable building blocks of DDSs is important for their clearance from human body. Accordingly, development of sustainable and biodegradable polymeric materials is highly demanding in development of sustainable DDSs. This perspective provides a general overview on sustainable polymers and highlights their potential applications in designing novel DDSs. Unsolved challenges and future prospects are discussed accompanied by offering potential solutions.
