Polyphenylene Sulphide - PPS 30% Carbon Fibre Reinforced

Sep 7 2001

Polymer Type

Thermoplastic

Advantages

Highest elongation at break, tensile strength, dimensional stability, rigidity and heat distortion temperature of all PPS grades. Better coefficient of friction against steel than glass reinforced grades. Good EMI shielding.

Disadvantages

Incorporation of carbon fibre produces negligible electrical resistance and can cause significant anisotropy in mouldings. Very expensive.

How are Graphene Batteries Made?

The primary distinction between graphene-based batteries and solid-state batteries lies in the composition of either electrode. Although the cathode is commonly changed, carbon allotropes can also be employed in fabricating anodes.
