Inclusion effect of gold and copper particles in a poly(amide) matrix that contains a thiophene moiety and Si or Ge atoms in the main chain

Abstract

Soluble pure silicon or germanium-containing poly(amide)s and their metallic composites (Cu or Au) were synthesized and characterized. Optical band gaps of pure polymer were comparable to an insulator behavior; however, the conductivity of some composites at several concentrations shows a diode-like behavior. Samples exhibit a monoclinic lattice mixed with amorphous structures. Specifically, polymer–Au composites showed distortion of this unit cell, associated with an increase in the conductance. This effect would be related to the coordination of the central atom (Si or Ge) to the incorporated metal, producing a homogeneous distribution of metallic particles within the system.MECESUP UCH 0601 and the corresponding authors thank the financial support provided by FONDECYT project: Nr 1095151, 1100015 and 1100882

Synthesis and thermal, optical and morphological characterization of oligomeric polyamides based on thiophene and alkyl/phenyl‐silane moieties. Study of the electrospun deposition process

“…These polymers contain silicon and/or germanium and several organic substituents into their main chain favoring the flexibility of the system, allowing chain folding. These characteristics make these polymers suitable for manipulation generating possible technological implementation …”

Silarylene-containing oligo(ether-amide)s based on bis(4-(4-amino phenoxy)phenyl)dimethylsilane. Effect of the dicarboxylic acid structure on some properties

“…From these works, several polymerizations have been developed with diamines containing diphenylsilane unit (Ph-Si-Ph), where the silicon atom is bonded to combinations of R 1 ¼ methyl and R 2 ¼ phenyl 8 as well as R 1 ¼ R 2 ¼ methyl 6,9 or phenyl. 6,[9][10][11][12][13][14][15][16][17][18][19][20] On the other hand, the inclusion of ether linkages into the chain of PAs has been explored by several research groups. Thus, diverse difunctional monomers have been synthesized and the properties of the derived polymers were established, with special attention to the solubility and their thermal parameters.…”

Synthesis of Fe2O3, Co3O4 and NiO nanoparticles by thermal decomposition of doped polyaniline precursors

“…In comparison to the free PANI, it is clear that doping raised the thermal stability of PANI. A polymer is considered as a thermostable material when a 10 % mass loss occurs at a temperature higher than 400-450°C [23].…”
