showed that solvent-drying rates provided quantitative information for the concentration variation in the phase-separating solutions, which lead to the formation of the particular cellular patterns. The morphology of PMMA films is analyzed by atomic force microscopy and scanning electron microscopy. Get cozy with the periodic table. The presence of solvents in the PMMA films was monitored until mass was kept constant. In the preparation of PMMA films, spin-coating can be used mainly because it allows fast and reproducible large scale production. Fabrication and characterization of polymeric optical by plasma fluorination process. Surface characterization of plasma deposited organic thin films. Morphological and thickness analysis for PMMA spin coated films. [ Links ], 15 Hass, D. E., Quijada, J. N., Picone, S. J., & Birnie, P. (2003). Torres et al. Nalgene /Poly Carbonate[PC] – Methylene Chloride dissolves this along with a long list on MeCl based cocktails. Florida: CRC Press. PMMA was dissolved in xylene, a mixture of MIBK-xylene and chloroform. Submitting a report will send us an email through our customer support system. Journal of Materials Science, 23(7), 2281-2293. http://dx.doi.org/10.1007/BF01111879. cyanoacrylate (super glue) & methylmethylacrylate (acrylic). It will be important to be able to classify similar solvents and plausible way for chemistry to happen. In this case, the refractive index was lower than the PMMA film alone. Rubber cement can work surprisingly well. However, around 80 wt-% ethanol content a solubility maximum was observed for PMMA as indicated by a decrease in the transition temperature. Gorilla glue is cheap effective and readily available, flooring and wood finishes offer a mixture for finer applications. Required fields are marked *Your email address will never be published or shared. 2.3.3 Surface morphology using scanning electron microscopy. Cyanoacrylate and acrylic [PMMA, MMA, etc] based polymers can get good bonding at the molecular level. This modification of PMMA film surface can be explained by the presence of fluorine atoms that decrease the surface free energy, increasing the values of contact angle[24,25]. Don’t risk your health and don’t waste your time. The ratio of MIBK-xylene was 1:1 (v/v). Read from thousands of the leading scholarly journals from SpringerNature, Wiley-Blackwell, Oxford University Press and more. Other solvents, by Fcalculated less than the Fcritical value were not shown in the response surface. Optik, 126(1), 74-76. http://dx.doi.org/10.1016/j.ijleo.2014.08.152. These PMMA films with lower roughness are treated with CHF3 plasma to produce the cladding. PMMA films dissolved in chloroform showed acceptable roughness for thin films when compared with other solvents – xylene and the mixture of MIBK-xylene. Acrylic "latex" paints often contain PMMA suspended in water. Based on this, chloroform, which has a solubility parameter range around 19.03 (J1/2 cm-3/2) is a good solvent for PMMA that has solubility parameter of 19.0 (J1/2 cm-3/2). PMMA films dissolved in xylene with thickness of 7.70 μm (Figure 4a) and MIBK-xylene with thickness of 7.57 μm (Figure 4b) showed increasing peaks and values (276 nm and 237 nm, respectively) compared to PMMA films dissolved in chloroform (171 nm) (Figure 4c). Table 4 Variance analysis of the PMMA films thickness. PMMA dissolved in chloroform - 15.36 (g/L), produced films with thickness of 10 μm by spin coating. MIBK has no a good solubility parameter for PMMA - 17.2 (J1/2 cm-3/2), which provides a difference greater than 1.5. The morphological in the silicon substrate and PMMA films dissolved in chloroform over silicon were observed using scanning electron microscopy and the SEM micrographs are showed in Figure 5. The water contact angles of all the surfaces were measured using contact angle of surface wetting (Tantec Half-Angle CAM - MICRO), with deionized water. Yamamura et al. The use of chloroform as a solvent can contribute to an acceptable roughness for polymeric optical films.
