Methanol-Supplemented Hierarchical Porous Breath Figure Structure
نویسندگان
چکیده
Honeycomb-shaped, hierarchical porous structure is fabricated using the breath figure method. Different solvents are used to fabricate membranes with five different concentrations spin coating. The diameter of pores controlled by polymer concentration as well solvents. Using methanol an additive solvent a homogeneous film achieved. Furthermore, effect on titania nanoparticles shows how particles confined in matrix. So, additional would be far more practical for synthesizing films pore sizes than standard procedure fabricating structure.

متن کاملTemplated ceramic microstructures by using the breath-figure method.
We describe the synthesis of two cyclobutadiene(cyclopentadienyl)cobalt-containing poly(p-phenylene ethynylene)s (PPEs) and their use as precursors for stable ceramic surface coatings. Organometallic PPEs were shaped into hexagonally ordered assemblies by using the breath-figure method. Such breath figures can be washed away with an appropriate solvent. Upon pyrolysis at 500 degrees C under eit...
