Improving Adhesives Characteristics With Nano-Reinforcements: A review

Adhesives are one of materials which mankind have been used from many years ago. Adhesive used in many cases and different situations, one of these uses is joints. Joints play an important role in structural uses, so the adhesive which use in joints, must meet the requirement of a structural adhesive and can be use in different service conditions and environmental situation. These days with changes in industrial needs, appearing new technologies, increased commercial availability and reduce prices, reinforcement of adhesives with nano reinforcements widely researched and reported. Nanoreinforcements due to their high ratio aspect and specific area, can improve polymer properties when add to polymer matrix as a reinforcement. In this paper, adhesive and mechanisms of adhesion explained, nanoreinforcements as an appropriate alternative to other kind of fillers and reinforcements are introduced, also those kind of adhesive properties which addition of nanoreinforcements made changes on them are explained. Nano reinforcements in 3 categories (inorganic, Carbon Nanotube and carbon Nanofiber) are introduced and their effects on adhesive polymer are discussed.
