Some issues in polymer nanocomposites: Theoretical and modeling opportunities for polymer physics

Block copolymer–nanoparticle composites: Structure, functional properties, and processing

“…Despite the fact that melt-mixing has many advantages, such as high efficiency and ease of operation, processing of BCP-NP hybrids through this method has certain disadvantages: (i) very long processing time due to slow equilibration kinetics that may potentially lead to the formation of kinetically trapped morphologies [289], (ii) order-to-disorder phase transition caused by high temperature processing, and (iii) lack of long range order due to polymer entanglement [43,290].…”

QDs Supported on Langmuir‐Blodgett Films of Polymers and Gemini Surfactant

“…In these situations, the organization of nanoparticles into ordered arrays can lead to new interesting properties, which are strongly affected by the morphology of the nanoparticle film [2][3][4][5][6]. Nanoparticles tend to agglomerate by attractive interactions [7,8] decreasing the quality of the devices. Therefore, the most recent efforts involve the use of polymer or surfactant molecules to minimize nanoparticles 3D aggregation.…”

Molecular mass dependence of point-to-set correlation length scale in polymers

“…1-3 Despite such commonalities, the influence of confinement upon the glass transition in polymeric systems has exhibited features, which are far richer and complex compared to the other systems. [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27] Overall, the only consensus that has emerged is that strongly adsorbing substrates locally elevate the glass transition temperature (T g ), whereas free surfaces locally depress T g . Beyond this general principle, a number of puzzling observations and controversies remain.…”
