Comparison of Theory with Experimental Data for Nanoclay-Filled TPU/PP Blend

Abstract

The mechanical properties of thermoplastic polyurethane (TPU)/polypropylene (PP) blends were investigated with special reference to the effect of type of polyurethane (ester-or ether-based), blend ratio, compatibilizer, and sequence addition of nanoclay. Tensile strength, stress at different elongations, flexural modulus, and abrasion resistance were analyzed and correlated with morphology. Blends of nanoclay filled thermoplastic polyurethane (TPU)/polypropylene (PP) of various compositions were evaluated by dynamic mechanical properties such as storage modulus (E′), loss modulus (E″), and dissipation factor (tan δ), at a frequency of 10 Hz over a temperature range from −100 to 200 °C. Finally different theoretical models were used to compare the experimental results with theoretical predictions.

Studies on thermal and degradation kinetics of cellulose micro/nanoparticle filled polylactic acid (PLA) based nanocomposites

“…Two different compositions of plasticizer 10 and 15 wt% PEG were used to understand its effects on the degree of crystallinity, melting temperature (T m ), glass transition temperature (T g ) and specific melting enthalpy (Δ H m ). 26–32…”

“…Two different compositions of plasticizer 10 and 15 wt% PEG were used to understand its effects on the degree of crystallinity, melting temperature (T m ), glass transition temperature (T g ) and specific melting enthalpy (DH m ). [26][27][28][29][30][31][32] The DSC analysis showed that (Table 2, Figure 1(a) and (b)) degree of crystallinity, T g and T m of neat PLA and 37.9%, 57.2 � C and 168.6 � C, respectively. The glass transition temperatures of the modified materials were decreased after adding 10 wt% and 15 wt% of plasticizer.…”

Morphological evolution and mechanical property enhancement of natural rubber/polypropylene blend through compatibilization by nanoclay

“…They showed that the use of PA6/organoclay masterbatch yielded finer dispersed phase morphology due to more clay was presented at the interface, which resulted in higher level of properties when compared with those obtained from other mixing methods. Other researchers also found that the mixing methods showed significant influence on morphology evolution and resultant changes in the mechanical properties …”

PBT/PC Blends Compatibilized and Toughened via Copolymers in Situ Formed by MgO-Catalyzed Transesterification

“…However, neat PBT has poor notched impact strength, so it is necessary to significantly improve its notched impact strength to meet more field requirements. Blending two or more polymers has proved to be a useful way to overcome some drawbacks of both materials without significantly compromising their advantages. − Blends of PBT and polycarbonate (PC) are of commercial interest because of their potential in complementarity. The amorphous PC provides impact resistance and toughness while the crystalline PBT provides enhanced chemical resistance and thermal stability.…”
