All of you use your toothbrush at least once a day. But, have you ever thought about the polymer used to make the bristles that clean your teeth every day?
The bristles of a toothbrush are made of nylon. Nylon is a thermoplastic with a silky texture. It is a polyamide with a backbone made of amide monomers. Because of the hydrogen bonding between the monomers, nylon’s backbone is symmetrical.
Nylon is resistant to biological and chemical agents. Imagine what would happen to your toothbrush if it reacted with saliva. It also resists abrasion to an extent; it won’t wear off due to rubbing. However, nylon degrades in the presence of UV light.
