1. A method of making a nanocomposite, comprising:
dispersing nanocellulose and nano-bentonite in water and mixing to form a mixture;
drying by heating the mixture at a temperature of at least 40° C. to form a dry mixture;
mixing the dry mixture with an alkylamine to form a nanocomposite composition;
heating the nanocomposite composition at a temperature of at least 100° C. to form a paste; and
drying and milling the paste to form the nanocomposite;
wherein the nanocellulose is prepared from date-palm tree leaflets; and
wherein the nano-bentonite is prepared from Saudi Arabia bentonite clay from the Khulays Mine.
