Pc-based nanoparticles have also been prepared employing a solution-casted method from an optically active metal-free Pc substituted with two binaphthyl units. Surprisingly, when the same process was carried out in the presence of a surfactant, the formation of hollow-sphere nanostructures was observed as revealed by TEM and SEM. Low angle XRD and electronic absorption spectroscopy revealed that these nanoscale hollow spheres are formed by stacked Pc molecules in a face-to-face configuration [213],... 

Perhaps the most common method for preparing polymer-nanotube composites has been to mix the nanotubes and polymer in a suitable solvent before evaporating the solvent to form a composite film. One of the benefits of the solution casting method is that agitation of the nanotube powder in a solvent facilitates nanotube de-aggregation and dispersion. Almost all solution processing methods are variations on a general theme which can be summarized in three major steps ... 

The oligothiophene films were prepared by solution cast methods and by vacuum deposition. Depending on the cast procedure, different layer thicknesses could be achieved. Preparation from solution either by drop casting or spincoating resulted in films ranging from 50 nm to 200 nm in thickness. Vacuum sublimation yielded very thin layers in the range of 10 nm to 15 nm, which nevertheless allowed to build-up and operate an OFET structure of molecular thickness as demonstrated in this chapter. 

The thin film consisted of large particle agglomerates, and most of the agglomerates were disconnected. XRD measurements revealed (image not shown) an amorphous structure without distinct X-ray reflection peaks. In conclusion the molecules deposited by solution cast methods are randomly oriented on the Si/Ti02 substrate. 

Mechanical Properties Chen et al. [2007] smdied the dynamic mechanical properties of films prepared by the solution casting method of PHBHV reinforced with HAp. The results indicated that at 75°C the storage tensile modulus of the polymer matrix, E , almost doubled by incorporation of 30 wt% HAp. The decrease in tan S was attributed to the hindrance of polymeric segment mobility by the nanofiller. Polyamide-69 has been reinforced with up to 10 wt% HAp [Sender et al., 2007]. The DMA results have pointed out an enhancement of the mechanical properties as a function of HAp content up to 5 wt% above this limit they deteriorated, probably due to the HAp agglomeration. 

In this study, in-plane and out-of-plane birefringences in various types of cellulose esters, including those prepared by the solution-cast method was examined. Birefringence is an important property that defines the optical behavior of optical films. The information on the molecular orientation and the birefringence... 

Conventionally, optical films in LCD application are produced using the solution-cast method, in which solvent is evaporated to obtain a film, to avoid the occurrence of irregular birefringence associated with extrusion process [5, 10], Therefore, the information on the molecular orientation and the birefringence of solution-cast films is significantly important. 

It is well known that the solution-cast method provides films without molecular orientation in the film plane, i.e., = riy [11],...

Pillai et al. described a comparison between two chemical functionalization strategies for the amine functionalization of multiwalled CNTs. The modified CNTs with optimum amine content were used to prepare PLA/CNT nanocomposites through solution casting method. The polymer nanocomposite thus prepared showed improved thermal properties when compared to the neat PLA [65]. 

The films of PBS, PEO and the binary blend of PBS/PEO were prepared by solution casting method. Pure PBS and PEO films with thickness of 200 10 pm were laminated together under pressure of 5 Mpa to obtain the bilayered film, and then used for preparation of gradient film. The laminated PBS/PEO film was annealed at 140 °C for 24 hours in an oven in the vacuum condition. By this way, we could generate a continuous gradient structure in the thickness direction, which is difficult to achieve by a conventional stepped multi-layer process. 

The films of pure P(BA-co-BT), pure PEO, binary blends P(BA-co-BT)/TDP(92/8 wt%/wt%) and PEO/TDP (92/8 wt%/wt%), and the ternary blend of P(BA-co-BT)/PEO/TDP containing a constant composition(8wt%) of TDP with various P(BA-co-BT)/PEO ratios were prepared by conventional solution casting method. 5wt% Polymer solution in 1,4-dioxane was stirred for 6-8 h and cast on a Teflon dish. The solvent was allowed to evaporate slowly for 1 day at ambient temperature. The resulted films were then dried in a vacuum oven at 50 °C for 2 days to remove residual solvent and subsequently compression molded between Teflon sheets for 3 min at 160 °C under pressure of 5MPa by using laboratory press (Mini Test Press-10, Toyoseiki Co., Japan).

Nitrile-functionalized graphene/PEN nanocomposites were prepared by an easy solution casting method [48]. 

Others have paid particular attention to the preparation of a SWNT/CHT film by the solution-cast method, then characterised its drug delivery properties. They found out that the the release of dexamethasone from the film was slowed down in the presence of SWNT compared with the release rate from pure CHT films. 

The miscibility of solution cast blends of poly(lactic acid) (PLA) and PVB has been reported (23). PLA was blended with PVB through a solution casting method using chloroform as solvent.
