Interfacial polymerization of an epoxy resin and carboxylic acids for the synthesis of microcapsules

Abstract: BACKGROUND: Microencapsulation technology promises new applications such as intelligent microstructures, phase change materials and self-healing composites. Microcapsule synthesis and characterization have been researched extensively; however, the well-known polymerization between epoxy resins and carboxylic acids has not been used to prepare microcapsules. RESULTS: Microcapsules were prepared by interfacial polymerization of an oil-in-water emulsion which contained a commercial epoxy resin and multifunctional… Show more

“…Interestingly, for PPD:DETA above 2:3 the wall morphology progressively changes from smooth to wrinkled, as also seen in Figure 8. This effect has been previously reported for polyamide capsules (Pascu et al, 2008;Salaün et al, 2009). The increase in cross-linker content makes the surface more uneven as a result of a more difficult diffusion of the monomers through the polymeric wall.…”

“…[25][26][27][28][29] And microcapsules offer thin closed structure within a restricted diameter range, and their internal van der Waals surfaces will regulate the phase change behavior of encapsulated PCMs in a precise fashion. The structure of PCMs results from a balance between short-range geometric factors and high pressure inside microcapsules compared to the unconned state.…”

“…In order to improve durability to washing or handle some auxiliary products are required to join microcapsules onto the fibres surface (Nelson, 2001); they are usually based on acrylic, polyurethanes, or silicone resins (Li et al 2008;Rodrigues et al, 2009). Some studies show how polycarboxylic acids can be used in encapsulation process (Pascu, Garcia-Valls, & Giamberini, 2008) or as a binder to join microcapsules (Voncina, Kreft, Kokol, Chen, 2009;Badulescu, Vivod, Jausovec, Voncina, 2008;Ziming, Genquan, Wai-man, Huiyi, 2011) or nanoparticles to fabrics (Montazer, Lessan, Moghadam, 2012;Wanga, Chen, 2005).…”
