WebIn Polymers, strong covalent bonds join atoms to each other in individual polymer molecules. Intermolecular forces (between the molecules) attract polymer molecules towards each other. Note that the properties exhibited by solid materials like polymers depend largely on the strength of the forces between these molecules. WebPolymer also publishes work on the technological application of polymers in energy and optoelectronics. The main scope is covered but not limited to the following core areas: Polymer Materials. Nanocomposites and hybrid nanomaterials; Polymer blends, films, fibres, networks and porous materials; Physical Characterization
