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.

“…Antibacterial PU coatings produced from epoxidized LO and PO-based polyol were also tested against E. coli [ 106 ], and the bioflavonoids karanjin and pongamol played an important role in the performance of the coatings [ 171 ]. MO-based PUFA also exhibited good antibacterial activities [ 146 , 147 , 148 ].…”

Nonedible Vegetable Oil-Based Polyols in Anticorrosive and Antimicrobial Polyurethane Coatings

et al. 2021

View full text Add to dashboard Cite

This review describes the preparation of nonedible vegetable oil (NEVO)-based polyols and their application in anticorrosive and antimicrobial polyurethane (PU) coatings. PUs are a class of versatile polymers made up of polyols and isocyanates. Renewable vegetable oils are promising resources for the development of ecofriendly polyols and the corresponding PUs. Researchers are interested in NEVOs because they provide an alternative to critical global food issues. The cultivation of plant resources for NEVOs can also be popularized globally by utilizing marginal land or wastelands. Polyols can be prepared from NEVOs following different conversion routes, including esterification, etherification, amidation, ozonolysis, hydrogenation, hydroformylation, thio-ene, acrylation, and epoxidation. These polyols can be incorporated into the PU network for coating applications. Metal surface corrosion and microbial growth are severe problems that cause enormous economic losses annually. These problems can be overcome by NEVO-based PU coatings, incorporating functional ingredients such as corrosion inhibitors and antimicrobial agents. The preferred coatings have great potential in high performance, smart, and functional applications, including in biomedical fields, to cope with emerging threats such as COVID-19.

Nowadays, the use of non‐traditional vegetable oils as polymer precursors is the subject of growing interest because of increasing price of crude oil and eco‐friendly approach. In this context, present work reports the synthesis of mahua oil fatty amide (MFA) from the mahua oil. The synthesized MFA was characterized by chemical and spectroscopic methods and utilized as a hydroxyl component of “two‐component polyurethane (2K‐PU)” system. The prepared 2K‐PU was used as wood protective coating material. The coating performance of the formulated 2K‐PU was evaluated by the measurement of mechanical, thermal and antimicrobial properties as well as water and chemical resistance. The study reveals that MFA can be used as the hydroxyl component in 2K‐PU coating system. MFA was derived from a relatively economical and renewable resource and the use of MFA can substantially reduce the cost of polyurethane coating formulations.
