Mechanical interlocking theory
WebFeb 12, 2024 · Mechanically interlocked polymers (MIPs), such as polyrotaxanes and polycatenanes, are polymer architectures that incorporate a mechanical bond. WebParticles with a smoother surface will generally have a lower frictional interaction and flow more easily than those that are rougher, assuming all other features are identical. Mechanical Interlocking Particles of a certain shape can mechanically interlock and resist flow. Inter-particulate forces of cohesion
