DLVO Interaction Energy Estimate
Combine a user-specified exponentially screened electrostatic repulsion with the non-retarded sphere–plate van der Waals term −AR/(6h). This is a simplified DLVO energy model, not a stability verdict for arbitrary colloids.

How DLVO Interaction Energy Estimate works
Combine a user-specified exponentially screened electrostatic repulsion with the non-retarded sphere–plate van der Waals term −AR/(6h). This is a simplified DLVO energy model, not a stability verdict for arbitrary colloids. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.1
- Interaction energy (J)
- The resulting interaction energy (j) returned as a number.
Limitations and assumptions
- Adsorption, wetting, and colloid models depend on surface preparation, temperature, pore structure, solution chemistry, and the chosen idealized isotherm or interaction model. Fitted parameters should not be extrapolated beyond their measurement range.
- Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.
Alternative or Complementary approaches
Check units and significant figures, compare the result with limiting cases, and use measured or source-specific constants where available. Laboratory, safety, and regulatory decisions require validated methods and appropriate uncertainty analysis.
