- 16. Performance Chemicals / Custom Manufacture / Advanced Materials We selected a scalable high shear exfoliaOon route: Ø Ambient condiOons. Ø No ultra-sonicaOon. Ø No aggressive chemistry. Ø Range of solvents – including water. Liquid phase exfoliaOon 3D RMs Solvent Dispersant 2D material producOon ExfoliaOon of 2D from 3D by high shear. Ø Range of mineral raw materials. Ø Scalable mineral processing. Ø Products are stabilised 2D dispersions and powders. Developed in CollaboraOon with AMBER at Trinity College Dublin. Full scienOfic details have been published: Paton, Coleman et al., Scalable producOon of large quanOOes of defect-free, few-layer graphene by shear-exfoliaOon in liquids Nature Materials Volume: 13, Pages:624–630 (2014) The Direct Liquid ExfoliaOon Process
