In this system, the cellulose whiskers isolated from tunicates self-assembled into a rigid percolation network, benefitting from its high aspect ratio and the high density of strongly interacting surface hydroxyl groups.
Therefore, the flow is suitable to create a sparse percolation network structure on the moving substrate, which is transparent yet conductive.
However, the affinity of both mesoscale fillers to epoxy phase show a dilute effect on PES concentration, furthermore, the domain growth of epoxy-rich along the filler percolation network sharpens the formation of epoxy matrix (or PES particle) structure [19].
The conductive nanoparticles are dispersed throughout the matrix during curing, and a percolation network is developed.
Such a routing and data transmission strategy will be referred to as percolation network scheme.
As explained further, orientation of the filler due to processing can destroy this percolation network. It is generally accepted that larger particles result in better TC, since they have less matrix-filler interfaces thus less thermal interfacial resistance [30-33].
The high aspect ratio of CNTs is beneficial in making percolation network at lower loading of the inclusions.
The occurrence of the rheological percolation network reveals, then, a physical gel that can be described by the Winter-Chambon method developed for polymer gel systems [56, 57], In crosslinking polymers, Winter and Chambon proposed that at the gel point the loss and storage modulus were congruent and proportional to of over the whole range 0 < [omega] < [infinity] of frequency, where n is the relaxation exponent (0 < n < 1).
This rapid change in electrical conductivity of the nanocomposites clearly indicates the formation of continuous interconnected conductive network chains of CNT-CNT in the nanocomposites, which is well known as percolation network. After that, the electrical conductivity of the PC/ PCL-MWCNT nanocomposites gradually increased with increasing the loading of MWCNTs in the nanocomposites, as shown in Fig.
All these properties are dependent on the loading levels of CB and its mesoscopic structure such as percolation network.
In melt state, the intercalated and exfoliated layers act as physical nodes forming a 3D percolation network (2), (21), (22), which improves the energy transport and the heat transfer caused by elastic waves.
