“…As OMMT content increased, some OMMT layers aggregated (Shi and Gan, 2008). The formation of OMMT aggregates reduces the interface area between polymer and OMMT layers, which decreases the mechanical properties.…”

Organo-montmorillonite (OMMT)/cis-1,4-polybutadiene rubber (BR) nanocomposites were prepared by solution intercalation. The microstructure of these composites was characterized by TEM and XRD. The effect of OMMT on mechanical properties, thermal stability and swelling behavior of the nanocomposites was investigated. TEM and XRD confirmed the intercalated structure of OMMT/BR nanocomposites. When the OMMT content was b12 mass%, the nanocomposites showed excellent tensile properties, which was attributed to the nanometer scale dispersion and stronger interactions between OMMT and BR chains. The introduction of a small amount of OMMT greatly improved the thermal stability and swelling behavior, which was attributed to the good barrier properties of OMMT layers.

“…Nevertheless, as the loading content of PDA exceeded 1 wt%, the ultimate T 5% outnumbered that of both neat PPC and PDA. Such phenomenon is quite special in that some researchers incorporated with fillers having T 5% higher than neat PPC while the ultimate T 5% usually would not exceed that of the fillers [9,12,31,32] . End-capping for PPC has been proven to be an effective way to improve thermal stability because the unzipping process of PPC from chain end at relatively low temperature could be inhibited through end-capping [5,7,8] .…”

“…However, the mechanical properties of the composites were not mentioned. In order to reinforce PPC, some researchers incorporated fillers, such as graphene oxide [10,11] and organophilic montmorillonite [12] into PPC. Besides, additives or fillers containing a large amount of proton donors, such as urethane [13] , o-lauroyl chitosan [14] , starch [15] and starch acetate [16] , wood flour [17] , succinic anhydrate [18] and hyperbranched poly(ester-amide) [19] , were utilized to perform hydrogen bonding with PPC which would improve the thermal stability and/or mechanical properties.…”

Inspired by the photoprotection, radical scavenging of melanin together with versatile adhesive ability of mussel proteins, polydopamine (PDA) nanoparticles were successfully prepared and incorporated into environmentally friendly polymer, poly(propylene carbonate) (PPC) via solvent blending. The prepared composites exhibited excellent thermal stability in air and nitrogen atmosphere and extraordinary mechanical properties. The composites displayed eminent increase of temperature at 5% weight loss (T 5% ) by 30100 K with 0.3 wt%2.0 wt% loadings, meanwhile, the tensile strength and Young's modulus were significantly improved from 11.5 MPa and 553.7 MPa to 40.5 MPa and 2411.2 MPa, respectively. The kinetic calculation indicated that improvement of T 5% is presumably derived from suppressing chain-end unzipping. The glass transition temperature (T g ) of the PPC/PDA composites increased by 810 K. This is probably due to hydrogen bonding interaction since the abundant proton donors along PDA chains would interact with proton acceptors like C＝O and C-O-C in PPC which would cause restriction of segmental motion of PPC chains.

“…This interaction may cause stress concentrating and resultant decreasing strength. [14,27] The hardness of the two types of RTV nanocomposites showed opposite trends. The hardness of RTV/FR-DOMt nanocomposites was almost decreased when more FRDOMt was added ( Figure 6).…”

The aim of our research was to study the effect of flame-retardant dendrimer modified organic montmorillonite (FR-DOMt) with different ratios on the structure and properties of room-temperaturevulcanised silicone rubber (RTV). The physical and mechanical properties of RTV nanocomposites were improved with the addition of FR-DOMt additives. The RTV nanocomposites exhibited better thermal stability. T onset of RTV/FR-DOMt-3 was 310 C, 100 C higher than that of pure RTV. RTV/FR-DOMt-3 nanocomposite possessed the highest elongation at break, 500%. This was 46% higher than that of pure RTV. In addition, these RTV nanocomposites showed an increased FR behavior. By adding 3À15 phr of FR-DOMt into pure RTV matrix, a linear decrease of burning rate together with an increase of LOI values were obtained. SEM and TEM observations of RTV/FR-DOMt-3 demonstrated that the exfoliated silicate layers dispersed uniformly in this nanocomposite.
