    سال: 2010
    خلاصه:

    The thermal stability of medium-density polyethylene (MDPE)/Montmorillonite nanocomposite was studied by TGA and DSC methods in a wide range of temperature. The dispersion of the MMT clays on microscopic scales was examined using a Transmission...

    Effect of nano-size calcium carbonate on short-term creep of polyethylene nanocomposite 

    نوع: Conference Paper
    نویسنده : سیدعبدالکریم سجادی; سیدمجتبی زبرجد; سمانه صاحبیان سقی; Seyed Abdolkarim Sajjadi; Seyed Mojtaba Zebarjad; samaneh sahebian saghi
    سال: 2010
    خلاصه:

    To evaluate the role of nano-sized CaCO3 on creep behavior of PE, a series of PE/CaCO3 nanocomposites were fabricated. To evaluate the dispersion of nanoparticles in PE matrix, scanning electron microscopy (SEM) was employed. ...
