A couple of thoughts...
When you say you do not want chemicals, what do you mean? Everything, literally, is a chemica. Water is a chemical, for instance. Saying that one does not want chemicals is ultimately meaningless.
If you mean you do not want harmful chemicals, again, what you mentioned are not. PFOA is a toxic chemical used in manufacturing, but no traces of it remain in the cookware you receive, and this is being phased out. PTFE (Teflon, essentially) is not harmful to humans, but it can emit gas at high temperatures which are harmful to birds which have mmuch more sensitive respiratory systemss.
The new ceramic nonstick uses neither PTFE nor PFOA in manufacturing, but the reviews seems to be mixed. The surface seems to work well initially, but after time, many people complain of sticking.
My personal preference is high-quality stainless steel such as All-Clad. AI use it for most cooking, but i also have a food good carbon steel skillets from France which, once seasoned, are vitually nonstick, and I use these for eggs. I prefer these because they hold up to hard use in the kitchen and do not need any sort of babysitting.
