“…Several analytical methods have been developed to analyze the non-isothermal crystallization kinetics studies [28][29][30][31][32]. In present work, the kinetics analysis can be done making use of Avrami's equation [33] modified by Jeziorny to describe the non-isothermal kinetics of the PEN-Ph [34]:…”

A novel single-component composite based on phthalonitrile end-capped polyarylene ether nitrile (PEN-Ph) was prepared successfully via hot compression. In the PENPh system, the crosslinking reactions and crystallization exist simultaneously, and the crystals are embedded in the crosslinked PEN-Ph matrix, which can work as reinforcement. Analysis of the Non-isothermal cold crystallization kinetics of the PEN-Ph system was performed by using differential scanning calorimetry (DSC), and the activation energy of the crystallization process is obtained to be 217.5 kJ·mol −1 . The DSC and SEM analysis provide the evidence for that there exists crosslinking reactions as well as crystallization behavior. However, the crosslinking reaction with excessive speed will restrict the crystallization behavior of the PEN-Ph. Furthermore, the DMA and mechanical measurements indicate that the glass transition temperature and mechanical properties are influenced by not only the crosslinking degree but also the crystallinity. The tensile strength of the single-component composite is 111.0 MPa, increased by about 10 MPa than that of amorphous PEN-Ph sheet.

“…In contrast, only very small loading levels of nanofillers are added to polymers to improve their mechanical properties [3,4]. The addition of ceramic nanoparticles into HDPE to enhance its performances has generated considerable research interest in recent years [5][6][7][8][9][10][11]. For example, Misra and coworkers studied the processing and mechanical properties of HDPE/CaCO 3 nanocomposites [8,11].…”

Maleated high density polyethylene (mPE) loaded with 2, 4, 6 and 8 wt% SiC nanoparticles (SiC np ) were prepared by injection molding. The effect of SiC np additions on the microstructure and mechanical properties of mPE were studied using X-ray diffraction (XRD), polarizing optical microscopy (POM), heat deflection temperature (HDT), tensile and Izod impact measurements. XRD and POM results showed that the SiC np additions reduce the crystallite thickness and spherulite size of mPE. HDT measurements revealed that SiC np additions enhance the thermal stability of mPE considerably. Tensile test showed that the addition of 2 wt% SiC np improves the Young's modulus and yield strength of mPE at the expenses of elongation at break and impact strength. SEM fractography was used to reveal the failure deformation of nanocomposites after impact test. The low impact strength of mPE/SiC np nanocomposites was related to the absence of particle cavitation and matrix fibrillation. The impact fracture deformation of such nanocomposites is discussed.

“…Increasing RH particle loading resulted in an abrupt drop in elongation at break for PP/RH/TiO2 and PP/RH/ZnO as compared to neat PP in (Figure 3). Generally, an incorporation of inorganic fillers into polymer composites enhances their mechanical properties such as tensile strength, elastic modulus but decreases impact strength and elongation at break [18,26,27]. Based on Figure 3, it also can be observed that elongation at break for PP/RH/TiO2 was higher than PP/RH/ZnO.…”
