A bio-based benzoxazine surfactant from amino acids

Abstract

A bio-based benzoxazine surfactant is synthesized using amino acids as an amine source, and may have potential use in cosmetics and cleaning products.

Review on the Accelerated and Low-Temperature Polymerization of Benzoxazine Resins: Addition Polymerizable Sustainable Polymers

“…Among naturally occurring amine sources, amino acids, dopamine and mussel-inspired catechol-derivatives hold great potential in benzoxazine chemistry. A few other animal sourced amine or phenolic compounds that were used for making benzoxazines are catechol [ 100 ], dopamine [ 114 ] and amino acids [ 100 , 373 , 374 ].…”

Recent development on bio‐based thermosetting resins

“…181,182 For example, Peng and coworkers invented a melamine sponges modified by cardanol-based benzoxazine, which showed ultrahigh oil/water separation efficiency (higher than 99.9%) and satisfactory permeation flux (1300 Lm À2 h À1 ). 182 Taking advantages of this nature, cardanol-containing benzoxazine resins were developed as surfactants 183 and superhydrophobic corrosion resistance coating. 184 The former was successfully used in preparing high internal phase emulsion and polystyrene particles were obtained accordingly.…”

“…184 The former was successfully used in preparing high internal phase emulsion and polystyrene particles were obtained accordingly. 183 The latter could maintain its superhydrophobicity after treated at 20 or 100 C for 60 days or friction by sandpaper 100 times. 184 The flame-retardant group could be introduced into bio-based benzoxazine monomer.…”

Low Temperature Curable Polyaniline/Bio-based polybenzoxazine Coated Cotton Fabric with Superior UV shielding and Oil-water Separation behaviours

“…Meantime, bisphenol-A was seriously studied for its toxic nature, which is a prime petro-chemical feedstock used for polymeric precursors viz., epoxies, polycarbonates, polyarylates, etc [18][19][20][21]. This motivates the researchers to explore the novel synthetic and bio-based phenolic precursors instead of bisphenol-A [22][23][24][25][26].…”

“…Cardanol derived benzoxazine is one among the bio based polymer that substitutes an environmentally hazardous petroleum phenolic derivatives like bisphenol-A, bisphenol-F in recent day's [27][28][29][30][31]. Cardanol-benzoxazines was rst prepared Cao et al [32]followed by various groups have developed skeletally modi ed monomers [23,[33][34][35]. In spite of environmental friendly nature, cardanol benzoxazines demand comparatively even high temperature for curing than that of conventional ones [36].In general, catalyst usage can considerably reduce the curing temperature of benzoxazines [37][38][39]Therefore continuous efforts are under progress to reduce the curing temperature of cardanol benzoxazines using catalysts [33,40].…”
