Figure 5 illustrates the FTIR spectra of (a) MMT and (b) OMMT
This in turn leads to larger expansion of OMMT
The above authors interpreted this behavior by chemical interactions of the alkoxyl silicone catalyst with hydroxyls present in OMMT
as well as with the hydroxyl-containing base rubber.
On the other hand, the incorporation of OMMT
into PA6/HDPE matrix significantly increased its tensile modulus.
The minority aPA component was modified with 2, 5, 7, and 10 wt% OMMT
prior to melt-mixing with gPP (PP/PP-g-MA blend in 80/20 composition); corresponding blends were also obtained as a reference.
The product was then filtered and repeatedly washed with hexane at room temperature to obtain the acyl-chloride functionalized OMMT
-COCl), a kind of gray powder.
Both PLA and TPU were dried in a vacuum oven at 80[degrees]C for 8 h, while OMMT
was dried at 90[degrees]C in a vacuum oven for 12 h.
Dispersion of the OMMT
in rubber matrix depends on two factors.
To date, numerous researchers have been reported on the PBS/OMMT
nanocomposites filled by various types of OMMT
Besides modifying the mechanical properties of the matrix (1), (11), the incorporation of OMMT
gives rise to an important perturbation of the fracture mechanism characteristic of the matrix.
The effect of HP and OMMT
contents on the physico-mechanical and thermal properties of the cured epoxy/OMMT
composites was investigated.
With regard to thermal properties, most reports indicate that regardless of the organic modifier, OMMT
nucleated PET crystallization, accelerated the crystallization rate, and promoted the formation of smaller, less-regular crystallites (23), (24), (26), (28), (31), (33), (34), (38), (42), (43).
