Particle Size Analysis and Characterization of Cassava (Manihot esculenta crantz) Stem Nanoparticles (CSNPs) via a Top-down Approach

Green Corrosion Inhibitory Potentials of Cassava Plant (Manihot esculentaCrantz) Extract Nanoparticles (CPENPs) in Coatings for Oil and Gas Pipeline

“…SiO 2 if added to coatings will improve the coating hardness, while the presence of CaCO 3 in coatings will form a precipitate that will serve as a protective film on the surface of the metal, thereby protecting the metal from corrosion. FTIR result revealed the nature of bond that exist in the CLNPs and GC-MS result showed various organic compounds that were presence in the CLNPs [48]. These organic compounds can be classified as fats, waxes, alkaloids, proteins, phenolics, simple sugars, pectins, mucilages, gums, resins, terpenes, starches, glycosides, saponins and essential oils.…”

“…These organic compounds can be classified as fats, waxes, alkaloids, proteins, phenolics, simple sugars, pectins, mucilages, gums, resins, terpenes, starches, glycosides, saponins and essential oils. All of which helps improve the properties of metallic coatings [47,48]. This chapter discuss the synthesis and characterization of CPENPs which can be used as additives to coatings for corrosion protection, especially coatings for oil and gas applications due to the properties as discussed by Kolawole et al [46][47][48].…”

“…CPENPs which comprises of cassava bark nanoparticles (CBNPs) [47], cassava leaf nanoparticles (CLNPs) [48] and cassava stem nanoparticles (CSNPs) [48] were obtained by first soaking for 24 h, after which ball milling for 60 h was carried out, to achieve a particles size below 100 nm which were estimated by SEM/Gwyddion software, XRD and TEM [47,48]. Trace elements such as O, Si, Ca, K, Fe and S, were revealed using EDX, which are hetero-atoms and can be added to coatings to help in inhibiting corrosion on metal surfaces [47,48]. Elements like Si and Ca would improve the strength of coatings as well as reduce corrosion rate of coated metals [47,48].…”

Elements like Si and Ca would improve the strength of coatings as well as reduce corrosion rate of coated metals [47,48]. XRD revealed compounds such as SiO 2 , CaCO 3 , Ca 2 (SO 4 ) 2 H 2 O and CaC 2 O 4 (H 2 O), these compounds would help in improving the mechanical properties of alloys or composites and coatings.…”

Therefore, CPENPs should not be left to waste as they are useful for additives in coatings.…”
