A dispersion of nanoplatelets or particles suspended in a carrier liquid is disclosed. The nanoplatelets or particles, e.g. graphene nanoplatelets, are derived from a layered material. The loading amount of nanoplatelets or particles in the dispersion is at least 20 mg nanoplatelets or particles per 1 ml of dispersion. The dispersion optionally further including a dispersant, the volume ratio of dispersant to the nanoplatelets or particles being less than 1 :1. A process for manufacturing the dispersion includes mixing the carrier liquid and the nanoplatelets or particles under high shear conditions. The dispersion can be used as an ink system, as a functional additive within an ink, coating or adhesive formulation, and/or in the manufacture of a nanoplatelet-polymer composite or a particle-polymer composite. 公开了种悬浮在载体液体中的纳米片或颗粒的分散体。该纳米片或颗粒，例如石墨烯纳米片，衍生自层状材料。分散体中的纳米片或颗粒的负载量为每1ml分散体至少20mg纳米片或颗粒。分散体任选地还包含分散剂，分散剂与纳米片或颗粒的体积比小于1:1。用于制造分散体的方法包括在高剪切条件下混合载体液体和纳米片或颗粒。分散体可以用作油墨系统，用作油墨、涂料或粘合剂制剂内的功能性添加剂，和/或用于制造纳米片-聚合物复合材料
