“…This close dependence of the particle size on the amount of added SNC demonstrates the key role of SNC in the stabilization process and evidences the strong SNC efficiency as a pickering stabilizer in emulsion polymerization of acrylic monomers. [35] This result is in agreement with our previous work and confirms that the stabilization aptitude of SNC is operative also in emulsion copolymerization, where two comonomers of different structure and hydrophobicity have been involved. [47] Similar results were reported for PBMA where the particle size of the latex dispersion reached about 600 nm for 4 wt.% SCN content and decreased to ca.…”

“…Controlled release of nitrogen and phosphorus from the coated materials with polyurethane coatings from castor oil reported similar behavior where the n values are above unity (Bortoletto-Santos et al, 2016;Cruz et al, 2017). However, for the slow release related to the second stage, the n values of the diffusion exponent were ranged between 0.09 and 0.25 (n<0.5 , Table 4) indicating that the mechanism release is a Fickian diffusion process (i.e., a typical diffusion trough coating thickness (Bortoletto-Santos et al, 2016;Li et al , 2019).…”

In an effort to enhance the efficiency of fertilizer use and minimize their negative impact on the environment, a novel biomass-based, functional controlled-release fertilizer was use to improve nutrient use efficiency and increase crop production systems for more sustainable agriculture practices. Here, biobased amino-oil (Priamine) mixtures were proposed as an outer coating with different layers for the control of phosphorus release from diammonium Phosphate (DAP). These hydrophobic coatings conferred excellent barrier properties and flexibility to coatings. The morphological characterization of the coated fertilizer was performed by Scanning Electronic Microscopy (SEM), and Electronic Diffraction X-ray (EDX) maping, and revealed the formation of a cohesive film and a good adhesion between DAP fertilizer and coating film. The release rate of nutrients (phosphate) in water was investigated by UV-Vis spectrophotometer. The effect of coating thickness was investigated on release time and diffusion coefficient of phosphor release in distilled water. Release time increased with the coating thickness. The diffusion coefficient of nutrient release decreased with the coating thickness. Compared with uncoated granule which is totally solubilized after less than 2 hours, the P release profiles of the coated granules reached the equilibrium stage approximatively after 98 and 126 hours when the DAP is coated with only Priamine single-layer (1L) and double-layer (2L), respectively. Moreover, the strategy adopted has successfully provided a very slow release and long-term availability of nutrients sources with biobased coating oil compared to uncoated fertilizer (DAP) and therefore exhibited promising application for sustainable development of modern agriculture and circular economic.

Excessive application of fertilizers negatively affects soil health, causes low nutrient utilization efficiency in plants, and leads to environmental pollution. The application of controlled-release fertilizer is gaining momentum to overcome this crisis. Engineered nanocomposites (ENCs) have shown tremendous promise for need-based delivery of agrochemicals (macro- and micronutrients, pesticides, and other agrochemicals). This review provides comprehensive coverage of synthesis of nanocomposites, their physical–chemical characterization, and techniques to achieve sustained release and targeted delivery to the crops, emphasizing their beneficial role in plant production and protection. Related aspects like feasibility of the application, commercialization of the nanoformulations, and biosafety concerns are also highlighted. This will be helpful to develop a critical understanding of the current state of the art in the controlled release of agrochemicals through nanocomposites. The pressing issues like scale up production, cost analyses, field-based trials, and environmental safety concerns should be given greater attention in future studies.
