Which of the following is FALSE about plasma modification advantages?

The statement about changing the bulk properties of the material without affecting the surface chemistry is inaccurate because plasma modification inherently targets the surface of a material. The primary purpose of plasma treatment is to alter the surface characteristics, such as enhancing adhesion, wettability, or introducing functional groups, while typically leaving the bulk properties largely unchanged.

While some treatments can lead to changes that may indirectly influence bulk properties, the primary mechanism of plasma modification is focused on surface chemistry. For example, introducing reactive groups or modifying surface roughness will not inherently change the material's bulk mechanical properties. Therefore, option C does not accurately represent the nature of plasma modifications.

In contrast, the other statements accurately depict advantages of plasma modification. Plasma processes can indeed function at near-ambient temperatures, allowing for the treatment of heat-sensitive materials. Additionally, the choice of gas used in the plasma process allows for targeted functionalization, meaning one can tailor the treatment based on the desired surface properties. Finally, plasma modification techniques can be applied to a broad range of materials, making them versatile tools in tissue engineering and material sciences.
