5 3D Interphase of PVA Bionanocomposite Films
Fig. 5.11 Relationships between interphase surface area (SA Interphase ) and interphase modulus
(E Interphase ) in a PVA/HNT bionanocomposites and b PVA/Cloisite 30B clay bionanocomposites,
as well as relationships between interphase volume (V Interphase ) and interphase modulus (E Interphase )
in c PVA/HNT bionanocomposites and d PVA/Cloisite 30B clay bionanocomposites, respectively
[5]
as a function of SA outer interface and SA inner interface for fully and partially embedded
nanoparticles within PVA matrices in PVA/NBC bionanocomposites, PVA/HNT
bionanocomposites and PVA/Cloisite 30B clay bionanocomposites, respectively.
All three bionanocomposite types demonstrated the same behaviour with increasing
SA outer interface and SA inner interface . Additionally, E Interphase can be improved remarkably in a nonlinear manner accordingly. In particular, fully embedded NBCs, HNTs
and Cloisite 30B clays yield consistently higher interphase modulus as opposed to
corresponding partially embedded nanoparticles when either inner or outer interface is considered. Elastic properties of interphase are strongly affected by interphase dimensions since interphase modulus tends to become higher with increasing
the surface areas of outer and inner interfaces Furthermore, as for fully embedded
NBCs, HNTs and Cloisite 30B clays, a higher modulus-increasing trend was evident
as opposed to that based on those partially embedded nanoparticles. This finding
