“…10 and Table S1 (Supplementary information) illustrate. According to the literature, pristine and oxidized MWCNTs stabilize PP [11,12], where the effect of MWCNT-COOH (Table S1, entry 3) is weaker than that of raw MWCNTs (Table S1, entry 2). Results show that MWCNTgrafted AOs 1 and 2 do not possess this stabilizing property if added to PP at 0.1 and 0.5 wt.% based on di-tert-butylphenol groups (Table S1, entries 4-6).…”

“…The hindered migration of MWCNTs resulting from their large diameter/length ratio (normally in the range of 1:1000) should fix the AO in the polymer. Ongoing work seeks to combine immobilization with other benefits of MWCNT/polyolefin composites, such as optical [12], electrical, and mechanical reinforcements [11]. In this paper, we provide a detailed description of the synthesis and a comprehensive characterization of two highly AO-functionalized MWCNTs (Fig.…”

“…Typically, single-walled carbon nanotubes are found in electronics and opto-electronics [3,4], field-effect transistors [5,6], composite materials [7], nanomechanics [8,9], and medical applications such as drug delivery systems [10]. The most common industrial application involves multi-walled carbon nanotubes (MWCNTs) compounded with polymeric materials to improve the mechanical [11,12], electrical [11,12], thermal [11], optical [12], and flame retardant [11,12] properties of the polymers. Our research interest focuses on the combination of above mentioned positive effects of MWCNTs on polymer compounds with the immobilization of the stabilizer.…”

Abstract. Development of a new generation of composite with unique thermal properties is an important task in the fields of science and technology where material is operated at high temperatures and exposure to a short-wave radiation. Recent studies show that carbon nanomaterials (fullerenes and carbon nanotubes) could improve the thermal, radiation and thermal-oxidative stability of the polymer matrix. In this article the development of a new heat resistant composite based on elastomer and carbon nanotubes (CNT) was performed and physicochemical properties of final product were evaluated.

“…Higher OIT or longer OIt indicates the better thermal oxidative stability of materials. [46][47][48] The OITs and OIts are determined by the onset of exothermic oxidation reaction of the PPS composites shown in the calorimetric curves (Fig. 11a and b).…”

SiC-fixed organophilic montmorillonite (OMMT@SiC) hybrid particles, with various proportions of SiC, were fabricated by electrostatic self-assembly in the presence of CTAB. Then, their PPS composites were prepared by melt-compounding. The results showed that the oxidation resistance and mechanical properties of PPS/OMMT@SiC composites was enhanced. When SiC content reached 5 wt%, the oxidation induction temperature of the PPS/OMMT@SiC composite achieved its maximum 513.1 C, which was 40.9 C higher than that of pure PPS. Meanwhile, the oxidation induction time of the obtained composite achieved a maximum of 25.2 min. These enhancements were attributed to the existence of the SiC, which prevented the aggregation of OMMT and facilitated OMMT to be further exfoliated in the PPS matrix. The sulfur atoms of PPS formed chemical bonds with SiC, meanwhile, a part of the surface hydroxyl groups of SiC formed hydrogen bonds with PPS, thus weakening the oxidation activity. OMMT and SiC effectively postponed the thermal oxidative degradation of PPS due to synergistic effects.
