Polymer Structure. The structure of a polymer is fascinating and complex. Understanding its structure helps in various applications. Polymers are large molecules made up of repeating units. ... The polymerization process is the chemical reaction where small molecules, called monomers, combine to form a large chain-like molecule, known as a ...

Achieving dual functionalities of hydrophobicity and excellent microwave transmission in a single material remains a significant challenge, especially for advanced applications in aerospace, telecommunications, and navigation engineering. Inspired by natural designs like chestnut burrs, bioinspired polyaniline (PANI) particles with tunable micro-/nanostructures through a facile template-free ...

Their "crosslinked polymer" chemical structure guarantees longevity but also makes these petrochemical-based materials—which comprise 15%–20% of all polymers produced—impossible to recycle.

Polyethylene terephthalate (PET) is a semi crystalline polymer possessing excellent chemical resistance, melt mobility and spinnability. The polymer is composed of repeating units as shown in the Figure 1.

Epoxy-terminated hyperbranched polymers (EHBPs) are a class of macromolecular polymers with a hyperbranched structure containing epoxy groups. They possess characteristics such as low viscosity, high functionality, and thermal stability, which endow them with broad application potential in materials science and chemical engineering. This study uses epoxidized soybean oil (ESO) as the raw ...
