An adhesive composition comprising
- modified cellulose fibers having a cellulose I crystal structure, an average fiber length of less than 150 nm, and an average fiber diameter of 1 nm or more and 300 nm or less;
- and
- a resin;
- wherein the modified cellulose fibers are cellulose fibers bound with a modifying group, wherein the modifying group comprises one or more members selected from the group consisting of (a) hydrocarbon groups, (b) silicone chains, and (c) alkylene oxide chains.
An adhesive composition comprising
- modified cellulose fibers having a cellulose I crystal structure, an average fiber length of less than 150 nm, and an average fiber diameter of 1 nm or more and 300 nm or less;
- and
- one or more resins selected from the group consisting of epoxy resins, urethane resins, acrylic resins, phenoxy resins, phenolic resins, urea resins, and melamine resins,
- wherein the modified cellulose fibers are anionically modified cellulose fibers bound with a modifying group,
- wherein the modifying group comprises one or more members selected from the group consisting of (a) hydrocarbon groups, (b) silicone chains, and (c) alkylene oxide chains, and
- wherein the modifying group is bound to an anionic group of the anionically modified cellulose fibers via an ionic bonding and/or a covalent bonding.
An adhesion method comprising adhering a structure with an adhesive composition comprising
- modified cellulose fibers having a cellulose I crystal structure, an average fiber length of less than 150 nm, and an average fiber diameter of 1 nm or more and 300 nm or less;
- and
