The poly (vinyl alcohol)-gold nanocomposites were finally drawn at 120°C up to a draw ratio (DR), defined as the ratio of the length before and after drawing, of 5. It is well known that the polymer molecules orient upon drawing, and it was evident from TEM images of thin sections of the drawn materials... [Pg.271]

Chemically bonded scaffolds are superior to physically adsorbed scaffolds in terms of the robustness of the resulting gold nanocomposites. Although most polymers introduced by the grafting from method are artificial polymers [80, 81], representative biopolymers such as oligonucleotides and peptides can also be introduced. [Pg.7]

Conjugation of as-prepared GNPs with as-prepared polymers is the most common and simplest method for preparing gold nanocomposites because mixing of the as-prepared materials can eliminate uncertainty factors such as the dispersion of GNP size and molecular weight. [Pg.7]

Metal nanopartides can also be cited. The characteristic properties of metal nanopartides and nanocomposites have been the subject of study because of their unique optical properties. Combining metal and polymer together enhances the optical properties of nanometals. Srivastava et al. 3] studied the optical properties of gold nanocomposites by changing the size and fraction of gold nanopartides. The optical properties of nanocomposite films of various thicknesses with different sizes and volume fraction of gold nanopartides have been studied using spectroscopic... [Pg.147]

It is notable that the gold nanoparticle concentration in the nanocomposite film is about 30 times lower than that of previously reported polymer/gold nanoshell systems. This can be explained by the particle size effect. As the size of particles decreases and approaches the nanometer scale, the surface area of the particles increases dramatically, and the nanoparticles act as effective scavengers of the polymer triplet state. This behavior is very important with regard to the use of the polymer/nanoparticles nanocomposite film as the active layer of PLEDs. Due to the high conductivity of gold nanoparticles, the injected electrons from the cathode can be transported directly to the anode resulting in the diode breakdown. As the nanoparticle volume fraction in the polymer increases, the device stability will decrease. [Pg.405]

Beside planar surfaces, Patten et al. [310-312] and Hallensleben et al. [313, 314, 322] prepared weU-defined nanocomposites by ATRSIP of from silica and gold nanoparticles. After spin-coating a solution of the polymer decorated particles onto mica, Hallensleben was able to image the single particles with the individual grafted polymer chains (Pig. 9.33). [Pg.428]
