To investigate effect of surface morphology on optical absorbance of active layer of PCDTBT: P[C.sub.71]Bm, UV-Vis spectra of the active layers prepared by using different
organic solvents were investigated.
Most
organic solvents are highly volatile and enter the body through the lungs, but can also enter through the mouth and skin.
A typical solvent based coating may contain a blend of up to a dozen or so
organic solvents with different vapour pressures, solubilities, evaporation rates, surface tensions etc to influence the balance of desired coatings properties as indicated earlier.
Organic solvents are typically present in paints, adhesives, glues, plastics and fuels (1).
"This development is particularly important because most of the existing polymer-based membranes are unstable in
organic solvents whereas the developed graphene-oxide membrane is highly stable," she added.
Thus, the MB fluorescence decreases with the addition of water in
organic solvent, in agreement with data presented in Figure 3.
The synthesis of polymers in
organic solvents, a widely adopted practice on industrial scales, has been gradually replaced by methods that employ water as the solvent.
ABSTRACT: The present study was conducted to analyze the effect of three different
organic solvents (Ethanol, Methanol and Acetone) on delignification of rice husk (basmati rice).
4) with acetonitrile as the
organic solvent on Zorbax 300SB-Diphenyl was similar to that on Zorbax 300SBCN, and the sorption strength decreased as the stationary phase changed from C3 to diphenyl to CN to C8.
Most of the work on the polymerization of HEMA in aqueous solution has been carried out using water-soluble photoinitiators and information is lacking on their behavior in
organic solvents. It would be worthwhile to evaluate the efficiency of these photoinitiators in the polymerization of HEMA in
organic solvents.
Under the same reporting conditions, it was found that the optimum sonication time to obtain good dispersion in
organic solvent was about 4 h where 2 h of tip sonication was enough for the surfactant aided dispersion.
[PC.sub.71]BM is an organic material chemically modified to be dissolved in an
organic solvent. To enhance the hole transport characteristic, a thin film of poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) [PEDOT:PSS] was prepared by using a commercially available material of PH1000 (Heraeus Clevios), which serves as a hole transfer layer interfaced with the anode and electron donor layer of PTB7.
