- DP60 Electronic material dispersants
DP60 dispersant This product is an innovative polyester-amine block copolymer aqueous solution. It realizes the construction of a three-dimensional network structure through molecular design. It is specially developed to solve the agglomeration problem of carbon-based nanomaterials (graphene, carbon nanotubes, ល។) and lithium-ion battery materials (silicon-carbon anode, ternary cathode, ល។) during wet grinding and spray drying. Characterized by FTIR and GPC, its molecular weight distribution D50 = 2000-5000Da, containing 30% active amino groups (calculated in KOH).
- ទិន្នន័យផលិតផល
ការតង្គនិគម：
It is a polymer containing multiple functional groups.
The structure is as follows:
Polyester segment: Contains carboxylic acid/ester functional groups;
Amino segment: Contains quaternary ammonium salt modified groups
Core mechanism:
- Multi-level dispersion system: The primary steric hindrance layer is formed by the flexible winding of polyester chains.
- Stereo-anchoring effect: The amino functional group forms a coordination bond with the surface defect sites of the carbon material.
- Solvent synergy: Forming a hydrogen bond network with NMP to improve mass transfer efficiency.
