What are Common Methods of Stress Relief in Nanotechnology?
Several methods are employed to relieve mechanical stress in nanotechnology, including:
1. Thermal Annealing: Heating nanomaterials to specific temperatures can relieve internal stresses by allowing atoms to rearrange into a lower energy state. 2. Surface Passivation: Coating nanomaterials with passivating layers can reduce surface stress and prevent the formation of defects. 3. Mechanical Polishing: Smoothing the surface of nanomaterials can help distribute stress more evenly and reduce stress concentrations. 4. Use of Flexible Substrates: Incorporating flexible substrates can accommodate mechanical deformation and reduce stress in rigid nanomaterials.
