Abstract:
By promoting the dispersion of modified HNTs inside the rubber matrix, the goal is to
improve the mechanical and thermal characteristics of the resultant nanocomposites
for damping application. Si69 and APTES, two silane-coupling agents, are utilized to
alter the surface of HNTs by creating covalent connections between silanes and
hydroxyl groups. By making this alteration, the hydrophobic Bromo butyl rubber
matrix is more feasible, which improves the overall performance of the
nanocomposites. Improved interfacial adhesion, increased dispersion of HNTs in the
non-polar Bromo butyl rubber matrix, and the insertion of certain functional groups
on the HNT surface are only a few benefits of silane modification. The research on
silanes, Si69 and APTES, for the modification of halloysite nanotubes (HNTs) and
their dispersion in Bromo butyl rubber (BIIR) is covered in this abstract. It is
important to achieve uniform dispersion of silane-modified HNTs in Bromo butyl
rubber; difficulties related to silane loading optimization, processing conditions, and
preserving the rubber matrix integrity during dispersion are discussed. Various
characterization methods, including Universal testing Machine (UTM),
Thermogravimetric Analysis (TGA) and scanning electron microscopy (SEM), are
utilized to evaluate the morphology and chemical interactions of the modified HNTs
and BIIR composites.
For applications like dampers, tiring inner liners and pharmaceutical stoppers that
require improved gas barrier qualities, the modified HNTs in Bromo butyl rubber
composites show promise. Future avenues for study include examining the impact of
various silanes, refining processing settings, and researching more general
applications in various polymer matrices.
