Industrial Applications of Polyacrylonitrile
| Industry | Application | Process |
|---|---|---|
| Textile Fibers | Fibers for apparel (e.g., wool substitutes, synthetic fur, sportswear) | Melt spinning or solution spinning of polyacrylonitrile resin to produce staple fibers or filaments |
| Textile Fibers | Precursor for carbon fiber | Pre-oxidation, carbonization, and graphitization of polyacrylonitrile precursor fibers |
| Construction | Concrete reinforcement fiber | Incorporation of polyacrylonitrile staple fibers into concrete mix to mitigate cracking and enhance impermeability |
| Filtration & Environmental Protection | Water treatment filtration media (liquid filtration) | Needle-punching or melt-blowing to produce felt or hollow-fiber membranes |
| Filtration & Environmental Protection | Air filtration (high-temperature flue gas dedusting) | Fabrication into filter bags for industrial flue gas dedusting |
| Cation Exchange | Ion exchange resin | Hydrolysis and amination of polyacrylonitrile to introduce functional groups, yielding chelating or ion exchange resins |
| Plastics Processing | Reinforced modified material | Blending with resins such as polyvinyl chloride (PVC), followed by extrusion or injection molding to improve product performance |
| Medical & Healthcare | Medical dressings | Solution spinning into nonwovens, leveraging high absorbency and softness |
| Chemical Industry | Encapsulation material for semiconductors/electronic components | Copolymer modification to produce engineering plastic for precision component encapsulation |
| Aerospace | Structural composite material | Carbonized polyacrylonitrile-based carbon fibers used as reinforcement in resin matrix composites |
Manufacturing Quality Control of Polyacrylonitrile
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance and Color | Visual Inspection, Colorimeter Method | Observe sample color and appearance state by eye or using a colorimeter to assess uniformity, presence of impurities, yellowing, etc. |
| Average Molecular Weight | Gel Permeation Chromatography (GPC) | Separate components of different molecular weights using a gel chromatography column; calculate weight-average (Mw) and number-average (Mn) molecular weights via a standard calibration curve. |
| Molecular Weight Distribution | Gel Permeation Chromatography (GPC) | GPC provides the molecular weight distribution width (Đ = Mw/Mn), reflecting the uniformity of the polymer. |
| Chemical Composition (Acrylonitrile Content) | Proton Nuclear Magnetic Resonance (¹H-NMR) | Quantitatively determine the ratio of acrylonitrile units to other comonomers by analyzing characteristic peak area ratios. |
| Crystallinity | X-ray Diffraction (XRD) | Measure diffraction peak intensities at specific angles to calculate the proportion of crystalline to amorphous regions, evaluating structural order. |
| Thermal Properties (Glass Transition Temperature, Tg) | Differential Scanning Calorimetry (DSC) | Measure heat flow under programmed temperature control to identify the glass transition temperature, indicating processing and service temperature ranges. |
| Thermal Stability | Thermogravimetric Analysis (TGA) | Record mass loss during heating to evaluate onset of decomposition and char yield, assessing thermal stability and pre-oxidation behavior. |
| Moisture Content | Karl Fischer Titration | Use a specific chemical reaction to measure trace moisture content; suitable for powdered or granular PAN resin. |
| Volatile Content | Thermogravimetric Method (Oven Method) | Heat the sample at a specified temperature for a defined period and measure the mass loss, indicating residual solvent or low-molecular-weight volatiles. |
| Residual Monomer Content | Gas Chromatography (GC) | Extract unreacted acrylonitrile monomer from the sample and quantify using gas chromatography to ensure product safety. |
| Fiber Mechanical Properties (if applicable) | Tensile Testing with Electronic Universal Tester | Perform tensile tests on PAN precursor fibers to measure breaking strength, elongation at break, and initial modulus for fiber quality evaluation. |
| Particle Size Distribution (for powdered PAN) | Laser Diffraction Particle Size Analysis | Use laser scattering principles to determine particle size distribution, which affects solubility and subsequent processing performance. |
