Effects of Antistatic Agent on the mechanical, morphological and Antistatic properties of polypropylene/organo-montmo- rillonite nanocomposites
Express Polymer Letters, 2009Co-Authors: W. S. Chow, W. L. ThamAbstract:Polypropylene (PP) and PP/organo-montmorillonite (OMMT) compounds containing Antistatic Agent (3, 6 and 9 wt%) were prepared using co-rotating twin screw extruder followed by injection molding. PP/OMMT composites were prepared by mixing of PP, OMMT and maleated PP (PPgMAH). The mechanical properties of PP blends and PP/OMMT nanocomposites were studied by tensile and impact tests. The effect of Antistatic Agent (AA) on the surface resistivity of PP and PP/OMMT nanocomposites were studied. The morphological properties of PP blends and PP/OMMT nanocomposites were characterized by using field emission scanning electron microscopy (FESEM). The intercalation of OMMT silicates layer in PP nanocomposites was characterized using X-ray diffraction (XRD). The impact strength of PP blends and PP/OMMT nanocomposites did not vary significantly by the addition of Antistatic Agent. The tensile modulus and tensile strength of PP/OMMT nanocomposites were slightly decreased with the increasing loading of Antistatic Agents. From FESEM analysis, the dispersion of Antistatic Agent in the PP matrix can be revealed. In addition, the surface resistivity of PP/OMMT compound was affected by the loading of Antistatic Agent. XRD results indicated the formation of intercalated nanocomposites for PP/OMMT/AA.

Preparation of Antistatic polystyrene superfine powder with polystyrene modified carbon nanotubes as Antistatic Agent
Composites Science and Technology, 2017Co-Authors: Min Zhang, Zhongjie Du, Hangquan Li, Chen Zhang, Wei ZouAbstract:A facile approach for fabricating Antistatic polystyrene (PS) microspheres used in 3D print had been carried out by introducing polystyrene onto the MWCNTs (MWCNTs@PS) surface. Firstly, poly (styrene-co-acryloyl chloride) (PS-co-APCl) was synthesized via free radical polymerization. Then azide-poly (styrene-co-acrylic acid) (PS-co-APAA) were prepared through the reaction between the acylchloride groups of PACl with the sodium azide. Subsequently, the azide groups of PS-co-APAA hich produced nitrene under high temperature, reacting with the sp2 carbon in MWCNTs. MWCNTs@PS thus obtained were characterized using FTIR, EDS, Raman, TAG and TEM, and used as Antistatic Agent in PS in-situ suspension polymerization. MWCNTs@PS/PS composite microspheres were characterized using TAG, SEM and TEM. Results revealed that PS was covalently bonded onto the surface of MWCNTs, which improved the compatibility with matrix. Thus, the Antistatic performances were enhanced by a well-constructed electrostatic discharge channel in the polystyrene matrix. As a result, the surface resistance of the percolation threshold was 3.54 × 108 Ω when the loading of MWCNTs@PS was at 0.5 wt%.The average diameter of MWCNTs@PS/PS microspheres was about 54 μm and the morphology was also very smooth, which could be used in 3D print.
