Preparation and properties of nanopolymer advanced composites: A review 65

is studied by SEM. The compatibility between new interlayer has been developed by
nanofiller. They found that the tensile strength of PVC sheets containing 10, 20, and
30 wt% of waste laminate (1, 2, and 3 wt% of PP) decreased as PP content increased.
In the samples with lower PP content, mechanical properties has got better as the
filler content increased, while with higher PP content, mechanical properties has
reached its maxima at about 6 wt% of CaCO 3 content.

2.8 Conclusions and summary of research findings

l The current study shows the application of low-content nanofillers can be an efficient tech-
nique for developing of polymers, composites, and blends.
l Currently, nanoclay, CaCO 3 , CNTs, SiO 2 , mica, and graphene are the most valuable
nanofillers displaying great reinforcing effects due to their high thermal stability, improved
mechanical strength, biocompatibility, and great abundance.
l It is concluded that nanoclay minerals and carbon nanotubes are the most promising alter-
native to other nanofillers for improving or modifying the polymer. Thus, the polymer com-
posite properties have exciting potential applications.
l In addition, the development of various preparation techniques and optimization of mixing
process is carried out to its important effect on the final properties.

Hence, this chapter expected to deliver the valuable evidence or literature information
for further research and the elaborative study of nanofiller based on macro-micro
nanopolymeric composites. Moreover, a short summary of some important research
carried out on nanofiller-reinforced polymer composites is presented in Table 2.11.
