Chemical Name or Material Polyacrylonitrile

Polyacrylonitrile (PAN)

Polyacrylonitrile (PAN) is a synthetic resin prepared by the polymerization of acrylonitrile. It is a member of the acrylic resin family and is a hard, rigid thermoplastic material.

Properties of Polyacrylonitrile:

  • Thermoplastic: Polyacrylonitrile is thermoplastic, which can be melted and remolded under certain conditions.
    Resistance to Solvents and Chemicals: PAN is a durable material resistant to most solvents and chemicals.
  • Resistance to Solvents and Chemicals: Polyacrylonitrile (PAN)is a durable material resistant to most solvents and chemicals.
  • Low Permeability to Gases: Polyacrylonitrile has low permeability to gases, making it useful in applications requiring gas barrier properties.
    High Melting Point: The melting point of PAN is above 300°C, but it degrades before melting under normal conditions.
  • High Melting Point: The Polyacrylonitrile (PAN) melting point is above 300°C, but it degrades before freezing under normal conditions.

Applications of Polyacrylonitrile:

Carbon Fiber Precursor: Polyacrylonitrile (PAN) is a precursor for producing carbon fibers. The fibers are heated and carbonized to create solid and lightweight materials used in the aerospace and automotive industries.

Polyacrylonitrile | 25014-41-9 FAQs

Polyacrylonitrile is a flexible synthetic polymer primarily used to manufacture carbon fibers, textiles, and filtration membranes. Its particular features, including chemical resistance and stability, make it essential in industrial and research applications.

Polyacrylonitrile's solubility changes with solvents such as dimethylformamide and dimethyl sulfoxide, allowing it to be used in the production of films, fibers, and membranes, which is crucial in sectors that require precision material fabrication and chemical resistance.

The solubility of polyacrylonitrile is determined by the solvent's polarity, temperature, and molecular weight. Polar aprotic solvents, such as DMF, increase solubility; others may need special conditions to dissolve them well.

Increasing temperature improves polyacrylonitrile solubility in appropriate solvents by lowering intermolecular tensions. However, too much heat might damage the polymer, demanding precise temperature control throughout production.

Polyacrylonitrile solubility necessitates specialized solvent systems and circumstances, making generating homogeneous solutions difficult. Overcoming these obstacles is vital to maximizing its applicability in advanced material and polymer research.
