The maturation of biobased polymer synthesis process has led to the rapid adoption controlled-release fertilizers (BCRFs). Despite this progress, loose structure, low cross-linking density, and poor water repellency current coatings result in short periods, which do not meet long-term nutrient demands crops throughout their reproductive phases. Moreover, existing modifications address these issues often involve addition external additives, can increase biotoxicity cost. In study, castor oil-based hyperbranched polyol (COHBPs) was synthesized from oil (CO) using a "one-pot method." We report development high density polyurethane (COHBPPFs) as coating for BCRFs. Gel content SEM analysis demonstrated that COHBPPFs exhibited degree cross-linking. Mechanical testing an electronic universal machine, along with AFM results, highlighted superior mechanical properties compared traditional coatings. significantly enhanced controlled release performance, 3% providing nearly 50 days release, marked improvement over conventional mechanism elucidated by modeling COHBPs PAPI. This study offers comprehensive examination CRF multiple perspectives provides valuable insights into cross-link environmentally friendly, renewable CRFs.

Materials derived from natural sources are demanded for future applications due to the combination of factors such as sustainability increase and legislature requirements. The availability efficient analysis vegetable oils (triacylglycerides) open an enormous potential incorporating these compounds into various products ensure ecological footprint decreases provide advantageous properties eventual products, flexibility, toughness, or exceptional hydrophobic character. double bonds located in many centers chemical functionalization, epoxidization, hydroxylation, nucleophile substitutions using acids anhydrides. Naturally occurring castor oil comprises a reactive vacant hydroxyl group, which can be modified via numerous approaches. This comprehensive Review provides overall insight toward multiple materials utilities functionalized glycerides additive manufacturing (3D printing), polyurethane (including their recycling), coatings, adhesives. work complex list investigated studied throughout available literature describes principles each selected application.
