Inclusion of poly(aniline) into MoO3

Abstract

Protonated emeraldine [poly(aniline)] has been encapsulated in Moo3 by first inserting aniline into its lattice followed by successful polymerization with (NH4)2S208; the new material is characterized by X-ray diffraction, IR spectroscopy, scanning electron microscopy and charge transport measurements.

Síntese e caracterização dos nanocompósitos K0,1(PEO)xMoS2 (X= 0,5; 1,2)

“…O interesse desses sistemas reascendeu drasticamente quando percebeu-se que essas matrizes poderiam ser esfoliadas (separação de lamelas individuais), produzindo uma suspensão de monolamelas em um solvente qualquer e que essas monolamelas poderiam ser posteriormente reagrupadas, após um processo de adsorsão de moléculas na sua superfície. A partir dessa descoberta, a técnica superou o limite da intercalação de cátions, passando ao encapsulamento de moléculas neutras 2 e até estruturas poliméricas [3][4][5][6][7] . Os materiais assim obtidos, consistem de uma mistura de dois compostos em nível molecular os quais passaram a ser chamados de nanocompósitos, em função das dimensões dos seus parâmetros de rede.…”

Effect of adsorbed polyaniline on the thermal stability of iron and arsenic oxides

“…The normal polimerization to prepare polyaniline has an enthalpy value of 439 kJ mol -1 for the emeraldine form 1 , and its protonation (doping) 2 and many other physicalchemical properties are connected to the presence of the -NH-group 3 . A great number of polymers, such as those derivative of polyaniline or other having some electroactive properties can be inserted into inorganic 2D, 3D or porous host solids [4][5][6] as phosphonates [7][8] , phosphates [9][10][11] , sulfides 12 and oxides [13][14][15] , displaying the so called nanocomposites [16][17][18][19][20][21] , which have enhanced their uncommon electrical properties.…”

Effects of Adsorbed Polyaniline on Redox Process on MoO3Surface

“…Electroactive polymers such as polyaniline can be inserted into inorganic two-dimensional, three-dimensional, and porous host solids (4 -6) such as phosphonates (7,8), phosphates (9 -11), sulfides (12), and oxides (13)(14)(15), producing the socalled nanocomposites (16 -21), which have enhanced or uncommon electrical properties.…”
