Inorganic nanofillers are often added into polymer/elastomer blends as a third component to modify their performance. This work aims to clarify the role of interface-localized spherical nanoparticles in determining the impact toughness of polymer blends. The selective distribution of titanium dioxide (TiO2) nanoparticles in poly(L-lactide)/poly(ether) urethane (PLLA/PU) blends was investigated by using scanning electron microscope. It is interesting to find that, regardless of the method of TiO2 introduction, nano-TiO2 particles are always selectively localized at the phase interface between PLLA and PU, leading to a significant improvement in notched Izod impact toughness. The moderately weakened interfacial adhesion induced by the interfacially-localized nano-TiO2 particles is believed to be the main reason for the largely enhanced impact toughness

“…of mechanical properties of polymer/elastomer/filler ternary nanocomposites is to tailor the phase morphology, especially the distribution of nanofillers in the matrix blends [28,29]. Generally, when nanofillers are introduced into an immiscible or partially miscible polymer blend, they often distribute heterogeneously, i.e.…”

“…[15][16][17][18] The role of the nanoparticles is to get specifically localized at the interface of both polymeric partners, to strengthen the interfacial adhesion between the partners and thus to enhance the overall material performances. [19][20][21] The use of nanoadditives (e.g. clay or silica nanoparticles) provides further advantages for polymeric blends such as enhanced material properties, ease of processing, and lower costs in comparison to block and graft copolymer compatibilizers.…”

“…However, up to now, there have been very few investigations on grafting of MA onto EPDM in the molten phase and its further utilization in thermoplastics [33][34][35][36][37], as well as on formation of EPDM/organoclay nanocomposites [38][39][40][41]. Uzuki et al [38] prepared the hybrid nanocomposites based on organophilic montmorillonite (MMT) and ethylene-propylene -diene rubber (EPDM) by a melt compounding process.…”

Polymer layered silicate nano-composites were prepared in melt by reactive extrusion (25:1 21 mm Rondol twinscrew compounding line) using poly(ethylene-co-propylene-co-ethylidenenorbornene) terpolymer (EPDM) as a matrx polymer, PP-g-MA and poly[(maleic anhydride-alt-1-octadecene)-g-PEO (poly(MA-alt-OD)-g-PEO) as functionalized polymer compatibilizer-internal plasticizer, octadecyl amine-montmorillonite (ODA-MMT) and dimethyldidodecyl ammonium -MMT (DMDA-MMT) as reactive and non-reactive nano-fillers, respectively. The formation of nano structural fragments, polymer blend composition-properties (thermal behavior and morphology) was studied using FTIR, XRD, TGA-DTG and DSC analysis methods. It was found that intercalation/exfoliation degree of EPDM macromolecules significantly depends on the origin and content of organoclays. Better results were obtained for nanocomposites prepared in the presence of reactive organo-filler (ODA-MMT) and PEO grafted alternating copolymer. The results of FTIR (chemical structure) and XRD (physical structure and exfoliation degree) analyses indicate that amidization of anhydride copolymer with alkyl amine groups of organo-filler and esterification of alternating copolymer with α -hydroxy-ω -methoxy-PEO occur in melt compounding in situ processing in the chosen extrusion conditions (barrel temperature: 120, 130, 140 and 145°C, twin-screw speed around 30-40 mrp). The glass-transition (Tg), melting (Tm) and recrystallization (Tc) temperatures strongly depend on the origin and content of organoclay and PEO-grafted copolymer-compatibilizer, respectively. Thermal behavior, crystallinity and thermostability of nanocomposites were significantly improved as compared with pristine EPDM terpolymer.
