The scientists developed a new way to make materials that can protect against heat. They used a special method to create a type of material called silica aerogel that has low heat conductivity. They then added other materials like polyethylene glycol or octadecanol to make a composite material with low heat conductivity and high heat storage capacity. This new material can keep things warm for a long time and is strong, water-resistant, and stable when exposed to heat. It could be used in devices for insulation and protection against heat. The method they used can work with different types of materials.
