The nanoparticle-Equilibrium polymer (or Wormlike micellar) system shows\nmorphological changes from percolating network-like structures to\nnon-percolating clusters with a change in the minimum approaching distance\n(EVP-excluded volume parameter) between nanoparticles and the matrix of\nequilibrium polymers. The shape anisotropy of nanoparticle clusters can be\ncontrolled by changing the polymer density. In this paper, the synergistic\nself-assembly of nanoparticles inside equilibrium polymeric matrix (or Wormlike\nmicellar matrix) is investigated with respect to the change in the strength of\nattractive interaction between nanoparticles. A shift in the point of\nmorphological transformation of the system to lower values of EVP as a result\nof a decrease in the strength of the attractive nanoparticle interaction is\nreported. We show that the absence of the attractive interaction between\nnanoparticles leads to the low packing of nanoparticle structures, but does not\nchange the morphological behaviour of the system. We also report the formation\nof the system spanning sheet-like arrangement of nanoparticles which are\narranged in alternate layers of matrix polymers and nanoparticles.\n
