phospholipids in NR. Phospholipid can act as coupling agent bonding the
α-terminal of NR with the CNT surface through cation-π interactions, which
make NR be competitive with NBR with respect to CNT hosting. Setting the
equilibrium CNT loadings experimentally determined by the wetting concept into
the Z-model recently developed in our previous work by keeping unchanged the
surface tension values of SBR and NBR a corrected value of surface tension of NR
was determined, which involves the effect of phospholipids [102].
