Researchers from the American Chemical Society have created a gel to protect fragile objects by adding
Padding in helmets helps protect people's headsfrom injuries while playing hockey, as well as during skateboarding and horse riding. However, due to a very strong blow or a fall on a hard surface, the brain still suffers. Thin, flexible materials that absorb better and dissipate the force of impacts.
Instead of elastomeric foam, the researchers madehydrogel films with gelatin and added corn starch granules. The result is a material that can reduce impact force by up to 15% compared to films made from pure gelatin.
Experiments also showed that gels containing 10% gelatin and 10–20% starch were ideal in terms of their flexibility and ability to absorb shock.
