Fatty acid – functionalized cellulose nanocomposites for vat photopolymerization

New sorbent-based hydrophobic alginic acid derivatives for fat removal in multi-pesticide residues: analysis of a fatty food sample

“…12 In addition, cellulose ester was modied with extracted fatty acids from sunower oil to be used as an additive in resins for vat photopolymerization. 13 Agarose fatty acid esters are another modied biopolymer produced by the esterication process and are used as hydrocolloid surfactants to investigate their emulsifying ability. 14 Also, agarose was modied using gallic acid to be used as coated lms for seafood preservation in food packaging.…”

One pot application of a green chemistry-based finish for cotton fabric, providing hydrophobic, flame retardant, and antimicrobial properties

“…This alteration enabled the hydrophobization of cellulose nanocrystals (CNCs), ensuring their effective dispersal within the polymeric resin. 26 In another study, the modification process involves the adsorption of quaternary ammonium salts, drawing inspiration from the techniques used to modify layered silicates in an organic manner. The modified series of cellulose nanocrystals (CNCs) obtained from this process can be dried from solvent and exhibit the potential for forming well-dispersed nanocomposites when combined with non-polar polymers.…”

Vat Photopolymerization of Nanocellulose-Reinforced Vegetable Oil-Based Resins: Synergy in Morphology and Functionalization

“…Coatings reinforced with acrylated NCC showed an increase of up to 60% in elastic modulus, while hexadecyltrimethylammonium functionalization yielded an increase in tensile strength by 36% and strain at break by 38%. In the most recent study, Maturi et al described NCC/commercial PLA resin composites, where NCC was functionalized with modified fatty acids from safflower oil (SOFA) . Vat photopolymerization resins with 0.25–5 wt % modified and neat NCCs were 3D-printed.…”

“…In the most recent study, Maturi et al described NCC/commercial PLA resin composites, where NCC was functionalized with modified fatty acids from safflower oil (SOFA). 25 Vat photopolymerization resins with 0.25−5 wt % modified and neat NCCs were 3D-printed. Unmodified NCC composites' mechanical performance was lower than for the neat resin, while NCC-SOFA/PLA composites showed up to a 9% increase in elastic modulus and 10% increase in tensile strength for loadings below 1 wt %.…”
