Polymers, as physical systems, are condensed matter assemblies composed of long, repeating-chain macromolecules whose collective behavior is governed by chain connectivity, conformational entropy, and intermolecular interactions. Their physical properties—such as viscoelasticity, glass transition, crystallinity, and diffusion—emerge from the statistics of polymer chains (e.g., Gaussian coils, entanglements) and their organization in bulk, solutions, or networks. In polymer physics, these systems are modeled using concepts like scaling laws, Flory–Huggins theory, and reptation dynamics to describe phase behavior, mechanical response, and transport phenomena across length scales ranging from molecular to macroscopic.
A study published in the International Journal of Nanotechnology has looked at the controlled synthesis and coating of magnetic nanoparticles (MNPs), specifically using oleic acid (OA) and polyethylene glycol (PEG). These ...
