Sub-Classification of Linear or Graft BCPs

It is worth mentioning that purely conjugated semiconducting polymer-based blocks having high rigidity (due to stiff aromatic backbone), are regarded as rod-like or stiff whereas the flexible blocks based on purely 

Composites (CMPs) represent class of materials made from two or more constituent phases (non-gaseous, one of which should be continuous) with significantly different physical or chemical properties, that when combined, produce a characteristically different material compared to the individual components [8,14,206]. The individual constituent phases remain separate and retain their identity in the resultant composite, and may be partially or completely (depending on strength of interactions between phase, scale at which they interact and their actual dimensions) recovered by suitable disintegration technique. 

It is worth mentioning here that in case of bulk CMPs, the concentration of interfacial regions is too low compared to matrix and reinforcements and often gets neglected. However, in case of NCs, where filler extend ultra-large 

Although the NCs are as old as nature itself, their importance was realized quite later and its foundations were laid only 25 years back. Therefore, it s worth to outline a brief account of the same. I must point that Nature is a maestro nanotechnologist that interestingly and incredibly has designed few of the most perfect and widely encountered NCs. The wood, shellac, and bone represent the simplest examples of natural NCs [11,14,364]. Intelligently and deliberately, in an attempt to emulate nature, the inspired man quickly learned from its ambiance and started the production of a variety of bulk composites, e.g., straw-reinforced mud bricks, concrete, and fiber-reinforced plastics (FRPs). In parallel, the efforts were also started and intensified to know, learn, and perfect the art of formation 

Depending upon state of aggregation of NF in the matrix and assumed thermodynamically equilibrated morphologies, CPs/ICPs-based NCs can be categorized into three main classes
