“…The nanocapsules showed a rapid drug release at pH 6.5 responding to the pH sensitive property of the polymer. In addition, other chemical reactions were also applied to preform polymeric nanocapsules by emulsion–coacervation method, such sonochemical reaction [ 66 , 107 ] or photopolymerization [ 108 , 109 ]. The studies of polymeric nanocapsules formulated by emulsion–coacervation methods in recent five years are summarized in Table 3 .…”

Polymer-based nanocapsules have been widely studied as a potential drug delivery system in recent years. Nanocapsules—as one of kind nanoparticle—provide a unique nanostructure, consisting of a liquid/solid core with a polymeric shell. This is of increasing interest in drug delivery applications. In this review, nanocapsules delivery systems studied in last decade are reviewed, along with nanocapsule formulation, characterizations of physical/chemical/biologic properties and applications. Furthermore, the challenges and opportunities of nanocapsules applications are also proposed.

“…Techniques for incorporating carboxyl groups into polymer latex particles have attracted attention in recent years . Latex particles bearing carboxylic functional groups, either at their surface or internally, have numerous applications in medical diagnostics, adhesives, impact modifiers, as well as paper and textile coatings . Water‐soluble carboxylic acid containing monomers, such as fumaric acid (FA), itaconic acid (IA), acrylic acid (AA), and methacrylic acid (MAA), listed in order of increasing hydrophobicity, are widely used in emulsion polymerization for the synthesis of carboxylated latexes.…”

We present a systematic study of incorporating carboxyl groups into latex particles to enhance colloidal stability and the physical properties of the latex. Statistical copolymers of methacrylic acid and methyl methacrylate) were synthesized via catalytic chain transfer polymerization (CCTP) in emulsion. The vinyl‐terminated oligomers were in turn successfully utilized as chain transfer agents for the formation of diblock and pseudo triblock copolymers via sulfur‐free reversible addition–fragmentation chain transfer polymerization (SF‐RAFT). These copolymers were characterized using 1H NMR, size exclusion chromatography (SEC), dynamic light scattering (DLS), dynamic mechanical analysis (DMA), contact angle measurements and matrix‐assisted laser desorption/ionization time of flight mass spectroscopy (MALDI‐TOF‐MS) techniques. © 2019 The Authors.

Hollow microcapsules with controlled mechanical strength are obtained from Pickering emulsion templates. The shell of the hollow microcapsules comprising UV‐curable resin and reactive silica nanoparticles enables tuning of the mechanical properties in a controlled manner. The results show that the particle stabilizer can be packed regularly on the oil–water interface and the shell thickness of microcapsules can be increased to 1–2 µm compared with traditional preparation methods. Hollow particles with thicker walls can prevent collapse and breakage. In this work, a nanoindentation device is used to measure the mechanical properties of hollow particles, and the results show a clear trend of reduced modulus and hardness decreases with increasing ratio of prepolymers in the reaction mixture. When the mass of PUA varies from 10% to 30%, the hardness decreases from 0.09 to 0.04 GPa, while the reduced modulus decreases from 0.17 to 0.06 GPa. The control of mechanical properties of the microcapsule can enhance its uses in conventional areas as well as in new fields such as precise micro force sensors etc.
