Study of optical and electrochemical properties of hybrid compouds (IOH) with Jeffamine (400) e Jeffamine (600) obtained by sol-gel method doped carbon nanotubes (CNT) and chromenes

Organic-inorganic gels hybrid matrix (HOI) doped with functionalized carbon nanotubes (CNT) and chromenes were prepared by sol-gel method and was characterized their optical and eletrical properties. The applicationof infrared spectroscopy (FTIR) spectroscopy and ultraviolet and visible allowed in o...
