Besides, tensile strength and Young's modulus are enhanced by 37% and 820%, respectively.
The nanohardness and Young's modulus are enhanced 2 4× to 1.5 GPa and ∼300 GPa, respectively.
The results indicated that as the silica content increased to 50 wt%, the ultimate tensile strength and modulus were enhanced to 191% and 614%, respectively.
Many nanocomposites have their thermal properties increased at 20°C 100°C compared to the pure matrix, the barrier properties to gas are lowered from one-third to one-sixth, and the modulus is enhanced 2 10 times compared to the pure polymer matrix.
The storage modulus is enhanced with increasing annealing temperature, accompany with glass transition temperature shifts to lower temperature, and the softening is also observed above annealing temperature in DMA measurements.
Varying the sheath-to-core flow rate ratios from 40 5 to 10 5, the tensile stress at break, the tensile strain at break, and the Young׳s modulus were enhanced from 24.51 MPa to 77.07 MPa, 567% to 1420%, and 247.25 MPa to 539.70 MPa, respectively.
For GAIM HDPE/PC microfibril composites, its yield strength is increased by 68%and66%6%, compared to the GAIM HDPE parts and the common injection molded (CIM) HDPE/PC composites, respectively; meanwhile, the Young's modulus is enhanced by 253% and 17%, compared to the GAIM HDPE parts and the CIM HDPE/PC composites, respectively.
Upon incorporation of only 1.5 wt.% MWCNTs, the tensile modulus of PA6 was enhanced from 2448 MPa to 4439 MPa, by about 80%, and the tensile strength was increased by about 23%.
It lowered Young's modulus, and this influence was enhanced by the increase of pH.
