An inorganic polymer is like Legos. You know how you can build a big castle or a small house with Legos? Just like that, scientists use different kinds of tiny things called molecules to build really cool stuff. Inorganic polymers are made from tiny things called atoms that don't have carbon in them (which is why we call them "inorganic").
Atoms are like tiny building blocks, and scientists mix them together to make new things. One group of atoms that scientists like to use are called "polymers". Polymers are special because they stick to each other really easily. Kind of like how Legos click together so easily. And when you put a lot of them together, you can make something really strong like a big tower!
Now, scientists take these polymer building blocks and mix them with other atoms that are also inorganic (remember, no carbon). This creates a really strong, hard material that doesn't change when you heat it up or cool it down (unlike the plastic Legos you might have).
Inorganic polymers are really smart, too! Scientists can add special molecules that can sense when they get wet or hot or cold, and change in response to that. This makes them super useful! They're used to make all kinds of things, like coatings on buildings that keep them waterproof, or in making special high-tech parts for cars or airplanes.
So in summary, Inorganic polymers are very strong materials made by mixing special molecules called polymers with other non-carbon atoms. They can't change when you heat or cool them, and they're good at detecting changes in their environment. People use them to make all kinds of cool things that are really strong and reliable.
