1. A method of making a lignocellulose incorporating methacrylate functionality from date palm biomass, wherein the lignocellulose comprises cellulose-hemicellulose-lignin, the method comprising:
obtaining date palm biomass;
drying the date palm biomass to obtain a dried date palm biomass;
sieving the dried date palm biomass to obtain a sieved date palm biomass;
extracting the sieved date palm biomass at a first temperature of 110° C. to remove waxes and resins from the sieved date palm biomass to obtain an extracted date palm biomass;
drying the extracted date palm biomass to obtain a dried extracted date palm biomass;
adding an acid to the dried extracted date palm biomass to obtain a mixture and continuously stirring and refluxing the mixture at a second temperature of 110° C. to obtain a refluxed lignocellulose residue;
cooling the refluxed lignocellulose residue;
dissolving the refluxed lignocellulose residue in a solvent to obtain a solution;
adding triethylamine and methacrylic anhydride to the solution to obtain a reaction solution mixture and stirring while heating the reaction solution mixture to react the triethylamine and the methacrylic anhydride with the solution to obtain a reacted solution mixture to provide methacrylate functionality to the lignocellulose;
pouring the reacted solution mixture into an ice-cold solvent to obtain a solution mixture and separating lignocellulose residue from the solution mixture via centrifuging to obtain a centrifuged lignocellulose residue;
drying the centrifuged lignocellulose residue to obtain a dried centrifuged lignocellulose residue; and
dissolving the dried centrifuged lignocellulose residue in water to obtain the lignocellulose incorporating methacrylate functionality.
