Footpath so that piled up between lamella and lamella easily by Van der Waals force, cause the stone in polymer nanocomposites
Agglomeration easily occurs for black alkene lamella, so as to weaken, limit the action effect of graphene.Particularly with nonpolar poly- third
Alkene, polyethylene etc., because the carbon conjugated double bond contained by graphene and the interaction of this kind of material are weaker, it is easier to cause graphite
Alkene lamella is reunited in its matrix.
There are some researches show, by by graphene under liquid-phase condition it is pre-dispersed, be redispersed in high polymer material and prepare stone
Black alkene masterbatch can preferably prevent the reunion of graphene.But when for high polymer material prepared by liquid phase graphene into masterbatch,
Because two-phase solid-liquid differs larger, processing difficulties.Therefore, we connect graphene by improving graphene masterbatch Preparation equipment
It is continuous to carry out solution dispersion and form masterbatch with high polymer material, so as to realize the stone of efficient, green prepare with scale polymolecularity
Black alkene masterbatch.
