While effective and fast, direct HF is extremely hazardous and tends to introduce more defects. [4, 5]<\/li>\n\n\n\n<li><strong>MILD Method (In Situ HF \/ LiF + HCl):<\/strong> The Minimally Intensive Layer Delamination method uses a safer mixture of hydrochloric acid and lithium fluoride (LiF + HCl) to generate HF <em>in situ<\/em>. This simultaneously etches Al and intercalates Li\u207a ions, yielding high-purity, larger-flakes, and highly conductive $\\text{Ti}_3\\text{C}_2\\text{T}_x$.

[2, 8]<\/li>\n\n\n\n<li><strong>Delamination:<\/strong> Gentle hand-shaking, manual manual shearing, or mild sonication of the sediment in water forces the separation of swollen galleries, producing a stable colloidal dark-green supernatant of single- or few-layer $\\text{Ti}_3\\text{C}_2\\text{T}_x$ flakes.

[9, 10]<\/li>\n\n\n\n<li><strong>Oxidation Prevention:<\/strong> Terminated surfaces ($\\text{T}_x = -\\text{F}, -\\text{OH}, -\\text{O}$) are prone to oxidation into TiO\u2082 over time; storage requires airtight, oxygen-free vials under inert gas (argon\/nitrogen) and refrigeration.
