Primitive path analysis
WebNov 29, 2024 · Primitive path analysis is used to visualize and quantify the structure of the composite ring-linear entanglement network. We measure the quantity of ring-linear threading and linear-linear entanglement as a function of ϕ R and identify with simple arguments a ring fraction ϕ R ≈ 0.4 where the topological constraints of the composite … Webthe prediction of the primitive path analysis (PPA).10,11,36 For This allows for relaxation of up to approximately 8Ne during the highly, but slowly, elongated sample, stress relaxation …

WebWe use a geometrical primitive path analysis to calculate average entanglement properties including canopy–canopy entanglements between pairs of PGNs. The longer chain systems are well entangled at both graft densities considered, and we find that as the monomer–surface interaction strength is increased (and the interparticle distance … WebApplying a primitive path analysis to strongly deformed polymer melts, the role of topological constrains in highly entangled polymer melts is investigated and quantified.
WebThis paper describes and provides Z1+, the successor of the Z- and Z1-codes for topological analyses of mono- and polydisperse entangled linear polymeric systems, in the presence or absence of confining surfaces or nano-inclusions. In contrast to its predecessors, Z1+ makes use of adaptive neighbor lists, and keeps the number of temporary nodes relatively …
