Applications of AO168 in Nanocomposite Materials
With the rapid development of nanotechnology, nanocomposite materials are being widely used in:
- Electronic materials
- High-barrier packaging
- Aerospace
- High-performance engineering plastics
- Thermally conductive and electrically conductive materials
Common nanofillers include:
- Graphene
- Carbon nanotubes (CNT)
- Nanoclay
- Nano silica
- Nano alumina
These nanomaterials can significantly improve polymer properties such as:
- Mechanical strength
- Thermal conductivity
- Barrier performance
- Electrical conductivity
- Heat resistance
However:
Nanomaterials also increase the oxidation risk of polymers
because nanofillers typically possess:
- Extremely high surface area
- High interfacial activity
- Greater heat accumulation
As a result, polymers become more susceptible to:
- Yellowing
- Molecular chain scission
- Melt degradation
- Reduced mechanical performance
during high-temperature processing.
Therefore:
AO168 (Antioxidant 168)
is becoming increasingly important in nanocomposite materials.
