  • Materials in Nokia : Available Technology Portfolio New technology? Maturity? Yield? Time?
  • Trends for Plastic Materials
    • Raw Material shortage
      • Polymers from renewable raw materials will become important
        • Current examples like
          • PHA (polyhydroxyalkanoate) grown in genetically modified corn plant leaves
          • PLA (polylactide) produced by the fermentation of sugars extracted from plants

        • Protein polymers are synthetic proteins created &quot;from scratch&quot; through chemical DNA (gene) synthesis, and produced in quantity by traditional large-scale microbial fermentation methods
        • Through genetic engineering, it will be possible to tailor the physical structure and biological characteristics of protein polymers to achieve required properties
        • Due to their synthetic design, protein polymers are capable of combining the biological functionality of natural proteins with the chemical functionality and exceptional physical properties of synthetic polymers

  • Amorphous metal alloys
    • Amorphous alloy
    • It used to solidify the metal melt by ultra high cooling rate to obtain a thin band with a thickness of 0.01 to 0.1 mm. When the cooling rate is larger than 10 6 K/s, the metal band will have a non-crystalline structure which is named “amorphous” or “metallic glass”.
