Nanoblends

From the mesoscopic model described in steps 2 and/or 3, calculate physical properties including spreading, surface energy, diffusion processes, and compare the simulation results with experimental data. This can be done for pure and nanoblended PFPE systems (Figures 24d and 25d). 

Tables 4.28 and 4.29 show effect of a montmorillonite nanoclay employed as a masterbatch (PolyOne Nanoblend 1001) in polypropylene on polypropylene-based composite containing 50% (w/w) maple wood flour and on flexural strength and modulus of the WPC.

Recently, microemulsion route [193,243,431-433] has been developed to enable strict control over molecular parameters (e.g., molecular weights of the homopolymers A and B, and the molecular weight and composition of the A-B-type linear DBG) that can lead to a stable co-continuous microemulsion (Figure 1.25a), indeed a nanoblend However, the major drawback of the co-continuous microemulsions is that they require polymers with similar lengths and sizes (low polydispersity) that are expensive... 

Another interesting nanoblending strategy is to blend the donor polymer with a sacrificial-insulating-polymer-based template that forms self-assembled nanostructures and acts as a PDA [438]. The chosen PDA polymer is soluble in a solvent that don t at all dissolve donor, so that once the film (active layer) has been deposited, the PDA can be selectively dissolved leaving behind a porous nanostructured pool of donor material, that... 

Poly(methyl methacrylate)/aramid nanoblends have been developed [58]. In detail, aramid from 1,5-diaminonaphthalene and 1,3-phenylenediamine with terephthaloyl chloride is incorporated in poly(methyl methacrylate) to get nanostmctured blends by physical interlocking. DSC studies indicated...

Nanoparticles/nanoblend systems are broadly classified into different categories as a vehicle to improve the efficacy of the therapeutic agents. This nanoblend may be fabricated with polymeric (synthetic and natural) materials. 

Polymeric micelle systems (PMS) are made by the self-assembly of amphiphilic block copolymers in an aqueous enviromnent. The important features of PMS are drug solubilization, controlled drug release, and drug targeting [26]. This chapter focuses and discusses the current scenario of natural biodegradable polymeric-based nanoblends for protein and gene delivery with a special emphasis on the pharmaceutical and biomedical approaches.
