Summary: In this study, self-cross-linking silylated polyvinylidene chloride (PVMBV) emulsions with core-shell structure were synthesized using seed emulsion polymerization method. The addition of vinyltrimethoxysilane (VTMO) cross-linker significantly improved the adhesion, thermal stability, toughness, and hydrophobicity of PVMBV films. Additionally, the barrier properties of PVMBV films were effectively enhanced by incorporating a small quantity of VTMO. These findings suggest potential applications of PVMBV coatings in multifunctional barrier coatings for vapor barrier, water barrier, weathering, and corrosion protection.

Summary: We describe a new method for synthesizing phase-separated multilayer core-shell emulsion particles with different morphologies, such as multilayer inverse core-shell (MLICS) particles and multilayer sea-island core-shell (MLSICS) particles. The morphology and size of the particles during the multistage polymerization process were characterized using transmission electron microscopy (TEM) and dynamic laser scattering (DLS) methods. The effect of the crosslinking agent, divinylbenzene (DVB), on particle morphology was also discussed.

Summary: Controlling the colloidal structure of multiphase latex particles can improve the mechanical properties of dried films in coatings. However, there is often conflict between optimal mechanical properties and good film formation at reduced temperatures. This study focuses on two-stage latex particles with a high glass transition temperature (Tg). The results show that film formation behavior in multiphase latex systems is influenced by the interplay between various colloidal and polymeric features, and a balance between low Tg film formation properties and high Tg polymer mechanical properties can be achieved by targeting a core-shell structure.

Summary: This study focuses on the synthesis and film formation behavior of hard-core/soft-shell latexes with varying compositions. It is found that the MFFT is significantly affected by the hard-core content, and film formation is restricted when the hard-core content is above 60%. Additionally, blending different core-shell particles can decrease the MFFT.

Summary: A scalable protocol for designing and 3D-printing polymeric core-shell particles is presented. The particles are synthesized via emulsion polymerization and their architecture and composition can be tailored. The size, mechanical properties, and chemical functionalities of the particles can be controlled to meet specific requirements for additive manufacturing. The self-assembly of the monodisperse particles into an ordered lattice structure during 3D-printing results in visible reflection colors according to Bragg's law of diffraction. The resulting colors can be easily tuned by adjusting synthesis parameters, making the particles promising for various applications such as decorative ornaments and smart optical coatings.
