The main research directions of material physics and chemistry are: (1) dielectric superlattice and its microstructure materials and devices (2) dielectric, ferroelectric thin films and integrated devices (3) artificial bandgap materials (4) all-oxide heterostructures and devices (5) nano-materials and nanoelectronics (6) new functional inorganic nonmetallic materials (7) design of microstructure materials (8) high performance calculation in material design (8) (1 1) biomaterials and biomedical materials (12) nano-photonic materials

Huaying mainly focuses on chemistry, only engineering, and has little to do with materials.

At present, there are six main research directions in materials science (1): new theory and technology of powder metallurgy (2) phase diagram research and material design (3) special new materials of powder metallurgy (4) alloying theory and new material development of nonferrous and rare metal materials (5) modern high-performance composite materials (6) functional materials of nonferrous metals.

Polymer chemistry and physics are related to organic polymer polymerization, as well as material processing, mainly processing polymer materials. The closest thing is material physics and chemistry. I study chemistry.

There is another job, you want to find a material processing-related enterprise, and most of the recruitment requires you to have a material background. Not so strict.
