    摘要: A method for forming a nanocomposite by olefin polymerization in which at least one cation-exchanging layered load material, selected from the group consisting of cation-exchanging, layered inorganic silicates and cation-exchanging, layered compounds other than silicates, is treated with acid to disrupt its layered structure and is combined with a catalyst that becomes activated for olefin polymerization when in contact with the acid-treated filler. An olefin is contacted by the activated catalyst - filler combination either (a) in the absence of an alkylaluminum co-catalyst or (b) with an alkylaluminum co-catalyst when the activatable catalyst is a polyalkylmetal compound, to form a nanocomposite containing polyolefin and the acid-treated filler. In a particular embodiment, sufficient filler is used to constitute at least 30 weight % of the nanocomposite to prepare a highly loaded nanocomposite masterbatch. A predetermined amount of one or more olefinic polymers can then be blended with the masterbatch to obtain a nanocomposite having a desired amount of loading. The filler is preferably clay, exemplified by montmorillonite. The catalyst is preferably a non-metallocene catalyst, most preferably a nickel complex bearing an a-iminocarboxamidato ligand.

    摘要: 一种PP材料的石墨烯色母料制作方法,包括以下实现步骤:将PP原料进行粉碎,在达到50-80目的PP粉末之后,开始与石墨烯材料混合,连续搅拌;待石墨烯材料均匀分布于PP粉末上,将混合物料送入循环锅炉中进行加热处理,并加入缓冲剂提高分散渗透效果;将循环锅炉内的温度进一步升高并不断搅拌,使石墨烯材料均匀分散与溶解;将溶解完成的色母料浆液冷却造粒,即形成色母料成品。石墨烯与PP材料相结合,可以改善PP材料的性能,并使色母料增添多样化的功能。该石墨烯色母料制作方法简单,易于实现,能够提高PP色母料的导热性能以及抗菌性能,促使所生产的产品表面光滑、结构紧密。

    摘要: The various embodiments of the present invention disclose an peroxide-vulcanised TPVs based on Hevea Brasiliensis natural rubber, polypropylene and solid sulfonic acid doped polyaniline [PAni.DBSA] with useful electrical conductivities (up to about 2.1 ± 0.2 S/cm] can be produced by using an internal mixer. The peroxide-vulcanised TPVs exhibit useful physical properties and also possess a reasonable good electromagnetic interferences shielding effectiveness. These peroxide-vulcanised TPVs could be recycled up to 4 times without significant loss of their EMI SE, electrical and physical properties. As a result, they have good potential to be used for manufacturing any EMI shielding products, such as EMI shielding seals and gaskets.
