Rubber Revival

Scientists have been working on a special kind of rubber called silicone rubber. They wanted to see how it would hold up over time when mixed with different materials like plant-based fillers and iron. The goal was to make the rubber stronger and more resistant to changes in temperature and light.

They put the rubber through a process that simulated years of aging in just a short period of time. After that, they tested its hardness, how well it handled heat, and how it looked. What they found was interesting - the rubber got about 10% harder when mixed with certain plant-based fillers like turmeric and goldenrod.

The researchers used some pretty cool techniques like TGA and FTIR to see how the rubber was breaking down. They also looked at it under a microscope to see any changes up close. One of the mixtures, which included a special kind of iron and a surfactant, seemed to really help keep the rubber stable.

In fact, this special mixture could handle temperatures that were 40 degrees Celsius higher than the regular rubber. That's a big deal because it means the rubber can be used in more situations without breaking down. The color of the rubber also changed, but in a way that showed it was still strong and useful.

These findings are exciting because they suggest that with the right mixtures, silicone rubber can be made to last longer and work better in different conditions. This could lead to all sorts of new uses for silicone rubber in the future.
