چکیده

Blue hybrid dye-clay nano-pigments (DCNPs) were synthesized using cationic exchange reaction. In fact, methylene blue (MB) as a cationic dye was replaced by some of cationic modifier of organoclay (i.e. Cloisite 15A, C15A). The obtained DCNPs were dispersed in an epoxy resin. The morphological properties of DCNP were evaluated and the mechanical performances of coating colored with DCNPs was compared with two other epoxy coatings which were prepared using two common organic and inorganic pigments (namely, C.I. pigment blue 15:2 and C.I. pigment blue 28). The samples were characterized using different techniques including XRD, TEM, DMTA. Results showed that the extent of intercalation/exfoliation of DCNPs in epoxy resin was better than that of C15A. It was found that the mechanical properties of epoxy/DCNP were superior comparing to the other coatings.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
