“…However, it is still challenging to control their crystalline structure, stability, and dispersibility in common solutions such as water and ethanol [8, 9]. As complexity of synthetic reactions increases, a thorough understanding of nanoparticle formation mechanism is needed [10, 11]. General mechanism is more or less understood.…”

Understanding nanoparticle growth mechanisms is crucial for the synthesis of nanocrystals with desired biological and chemical properties. Growth of nanocrystals by oriented attachment (OA) is frequently reported as a method supplementary to the classical growth by Ostwald ripening (OR) process. In this work, ZnO nanoparticles (NPs) were prepared by wet chemical method. Size/shape evolution of ZnO NPs in ethanol solution was systematically studied using transmission electron microscopy (TEM), dynamic light scattering (DLS), and X-ray diffraction (XRD). In addition, a detailed process of the nanoparticle growth-based OA mechanism is discussed. Results revealed that reaction conditions affect size/shape of NPs and change their surface structure: prior to OA, the surface of adjacent particles transformed into their “rough” states. We proved that stability of the solution was significantly improved in this state. Such a state is important to design nanoparticles with high stability and as nano-suspensions with special physical and/or chemical properties. This state is a critical step in enhancing OA process.

“…To overcome the above mentioned defects, encapsulation of organic pigment particles by an adhesive polymeric shell was regarded as one of the most effective methods. To date, encapsulation of organic pigment via emulsion polymerization, [13][14][15][16][17] miniemulsion polymerization [18][19][20][21] and suspension polymerization [22][23][24] has been reported by many researchers. It was found that the pigment dispersibility in the polymer lm was signicantly improved aer encapsulation.…”

[43,44] Herein, a new class of aqueous bio-latex colloids (A-LNP-pBM) composed of an allylated LNPs (A-LNPs) core and a pBM acrylate polymer shell from seeded emulsion polymerization is developed and their molecular interface properties (i.e., surface functionality and hydrophobic monomer conversions) and physicochemical behavior of nanostructures are studied. Thermally dried and annealed bio-latex films are investigated in terms of nanoparticle (core)-stimulated morphology using small-angle X-ray scattering (SAXS) and scanning electron microscope (SEM) and correlated to quantitative nanomechanical atomic force microscopy (AFM) measurements.…”

advanced functional templates, such as porous supraparticles and complex crystal superstructures, due to their facile surface functionalization and tunable colloidal assembly. [1][2][3][4][5][6] Films fabricated from latex colloids with a unique core-shell morphology is a novel class of nanoparticlepolymer composites that synergistically integrate the versatility of nanoparticles (core) with the processability and diversity of the corona polymers (shell). [5,7] Two techniques, that is, seeded free-radical emulsion polymerization and controlled radical emulsion polymerization of amphiphilic block copolymers (commonly a macro chain-transfer agent), have proven effective in devising multifunctional coreshell latex colloids. [7][8][9] In the above-mentioned techniques, the seed of the latex colloid or the hydrophobic core that is derived from the polymerization-induced self-assembly in aqueous dispersion functions as an interfacial modulator to direct hydrophobic polymer growth on the core surface or in the core, respectively. [10,11] Compared with controlled radical emulsion polymerization, seeded emulsion polymerization offers more possibilities to vary the constituents of the core (e.g., polyesters, polyolefins, polyvinyl acetate, acrylics, polysaccharides, silica) and distinct shell geometries, such as raspberry-and dumbbell-like features, Fabricating bio-latex colloids with core-shell nanostructure is an effective method for obtaining films with enhanced mechanical characteristics. Nanosized lignin is rising as a class of sustainable nanomaterials that can be incorporated into latex colloids. Fundamental knowledge of the correlation between surface chemistry of lignin nanoparticles (LNPs) and integration efficiency in latex colloids and from it thermally processed latex films are scarce. Here, an approach to integrate self-assembled nanospheres of allylated lignin as the surface-activated cores in a seeded free-radical emulsion copolymerization of butyl acrylate and methyl methacrylate is proposed. The interfacial-modulating function on allylated LNPs regulates the emulsion polymerization and it successfully produces a multi-energy dissipative latex film structure containing a lignin-dominated core (16% dry weight basis). At an optimized allyl-terminated surface functionality of 1.04 mmol g −1 , the LNPs-integrated latex film exhibits extremely high toughness value above 57.7 MJ m −3 . With multiple morphological and microstructural characterizations, the well-ordered packing of latex colloids under the nanoconfinement of LNPs in the latex films is revealed. It is concluded that the surface chemistry metrics of colloidal cores in terms of the abundance of polymerization-modulating anchors and their accessibility have a delicate control over the structural evolution of core-shell latex colloids.
