Chemical resistance is vital in nanotechnology for several reasons: 1. Durability: Materials exposed to harsh chemicals can deteriorate quickly if they lack adequate resistance, leading to failure in applications. 2. Safety: Ensuring that nanomaterials do not break down in the presence of chemicals is essential for maintaining safety, particularly in biomedical applications. 3. Performance: The overall performance of nanotech-based products often depends on the stability of the materials used. Chemical resistance ensures that these materials maintain their intended properties throughout their lifecycle.
