Table 3 Comparison of different modification methods
Modification method | Stability | Cost | Uniformity | Control precision | Refs. |
|---|---|---|---|---|---|
Defect and Doping | Moderate; defect states can be unstable | Low | Low; Difficult to achieve uniform doping | Low to moderate | |
Polymer | Low; sensitive to temperature | Moderate | Moderate; interfaces can be inconsistent | Moderate; | |
Functional Group | Low; functional groups may degrade over time | High | High; depends on the preparation process | High | |
Heterogeneous structure | High; stable van der Waals interactions | High | Moderate to high; depends on the quality of the materials used | Moderate to high |
