Adhesion issues in nanotechnology commonly include:
1. Weak Bonding: Inadequate adhesion can result from weak intermolecular forces between surfaces, leading to delamination. 2. Contamination: Surface impurities can inhibit proper bonding, causing defects and failures. 3. Environmental Factors: Temperature, humidity, and other environmental factors can degrade adhesion over time. 4. Material Mismatches: Different thermal expansion coefficients can cause stress and separation at interfaces.
