American chemists from FAMU-FSU’s College of Engineering have discovered a new way to create adhesives using the natural attraction between positively and negatively charged materials. The key to the invention was ordinary table salt. The research was published in the scientific journal magazine American Chemical Society (JACS).
The team studied how the shape of a compound affects its stickiness using two polymers: one with a branching main chain and one with a linear chain.
One of the key findings of the research was that simply adding sodium chloride (table salt) transformed strong but brittle polymers into strong and flexible ones.
Most adhesives are either strong or fairly flexible, but it is difficult to find formulations that can do both. Chemists noted that the amount of salt is key to making the glue strong yet flexible.
According to the scientists, their discovery lays the foundation for the creation of better industrial adhesives and could also find use in biomedical formulations to couple tissue with drug delivery functions.
Russian scientists before developed New non-toxic polyethylene based adhesive.
