Synthesis and Application of Non-Toxic Superhydrophobic Phenyl Substituted Pyrazolidine Based Benzoxazine Coating for Oil-Water Separation and Corrosion Resistance

Advancing coatings with polybenzoxazines: insights into molecular design, synthesis, and modification

“…Cotton fabrics coated with poly(PPBP-dda) and poly(PPBP-oda) achieved exceptional WCA values of 154.2° and 153.5°, respectively. 37 Additionally, oil–water separation utilizing the poly(PPBP-dda) coated fabric demonstrated excellent flux values (6330 L (m 2 h) −1 ) and separation efficiency (98%). Harinei Srinivasan et al synthesized a series of bio-benzoxazines from thymolphthalein (THP) and various aliphatic amines (ba, ha, eha, dda, oda).…”

“…Mild steel (MS) specimens coated with poly(PPBP-dda) exhibited 81% efficiency and a charge transfer resistance ( R ct ) of 280 Ω cm −2 against corrosion in artificial seawater. 37 Q-Benzoxazines using 8-hydroxyquinoline (Q) together with various monoamines (ba, ha, oa) and aniline (a) act as effective corrosion inhibitors when applied to MS due to their molecular structures containing lengthy alkyl chains. 39 Similarly, ha and oa were utilized to enhance hydrophobic and corrosion resistance properties.…”

“…P. Nivinkrishnan et al synthesized a series of PBZs derived from N -phenyl pyrazolidine scaffold-based bisphenol (PPBP) and long chain aliphatic amines; both the PPBP monomer and the corresponding PBZs displayed strong antibacterial activity, attributed to the lengthy dodecyl (C-12) and octadecyl (C-18) chains, with closely packed molecular arrangements contributing to rough surfaces. 37 Curcumin is expected to enhance antibacterial and antiviral activity, physical and chemical resistance, anticorrosion capabilities, and resin durability. Chaitany Jayprakash Raorane et al incorporated the properties of curcumin into the PBZ network to synthesize poly(Cu-A), for use as an environmentally benign, non-toxic green coating with inhibitory effects on biofilm formation.…”
