Review:
Nanoclays (montmorillonite)
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
Nanoclays, specifically montmorillonite-based nanoclays, are nanometer-scale layered silicate minerals used as functional additives in various industries. They are characterized by their high surface area, exfoliated or intercalated structures, and remarkable ability to improve mechanical, thermal, and barrier properties of composite materials, especially polymers. Due to their unique structure, nanoclays are extensively researched for applications in packaging, automotive parts, electronics, and biomedical fields.
