چکیده
Cellulose nanocrystals (CNCs) show promise for enhancing properties of waterborne latexes and coatings. Miniemulsion polymerization is a promising route to obtaining well-controlled latex distributions sufficient encapsulate CNCs in the monomer phase. Here, we demonstrate first miniemulsion resulting encapsulation that incorporates costabilizer, water soluble initiator, comonomer mixtures, aspects are important practical implementation. were added phase as either unmodified (umCNC) or one two functionalized forms: modified with isocyanatoethyl methacrylate (mCNC, containing polymerizable vinyl group) grafted butyl acrylate/methyl copolymer (gmCNC). The gmCNCs incorporated successfully into acrylic particles. In contrast, umCNCs located outside formed Interestingly, mCNCs coagulated during polymerization, highlighting challenge utilizing polar reactive acryloyl CNC surface modifiers lead migration from droplet

متن کاملSynthesis of asymmetric inorganic/polymer nanocomposite particles via localized substrate surface modification and miniemulsion polymerization.
Asymmetric nanocomposite particle pairs of polystyrene and silica were prepared via one-step miniemulsion polymerization for the first time. The transmission electron microscopy images showed that these nanocomposite particle pairs were monodisperse and highly asymmetric in morphology. The key to obtaining the asymmetric nanocomposite particle pairs was the combination of miniemulsion polymeriz...

The first stage to have access to a reservoir is the drilling operation. The proper development of this operation plays a major role in increasing productivity. It must be pointed out that the drilling fluid (mud) is pivotal in achieving this objective. Among these fluids, water-based fluids are the most common ones, which have been utilized to drill approximately 80% of all wells and are m...
متن کاملContinuous Miniemulsion Polymerization
Most miniemulsion polymerizations are carried out in batch reactors. However, continuous reactors or continuous reactor trains can provide a high level of consistency when operated at steady state. In this feature article, progress in continuous miniemulsion polymerization will be reviewed. Special attention will be given to issues of monomer diffusion and secondary nucleation. A large portion ...
