“…[7][8][9][10][11][12] In most recent literatures, nano-inorganic particles, such as TiO 2 , SiO 2 , and Fe 2 O 3 , were used as seeds to synthesize composite microspheres. [13][14][15][16] There are few approaches to apply nano-ZnO as inorganic core to synthesize inorganicorganic composite microspheres. Zinc oxide (ZnO) nanoparticle, as one of the multifunctional inorganic nanomaterials, can be potentially applied to many applications UV-shielding materials.…”

Zinc oxide=high-density polyethylene nanocomposites with high-UV-shielding efficiency were reported. Zinc oxide nanoparticles were synthesized by the homogeneous precipitation method and calcination of the precursor at different temperatures. Zinc oxide= high-density polyethylene nanocomposites were subsequently prepared from high-density polyethylene and as-prepared zinc oxide nanoparticles via melt mixing process. The structural properties of the as-prepared zinc oxide nanoparticles and nanocomposites were studied in detail using X-ray diffractometer, Fourier transform infrared spectrometer, thermogravimetry, differential scanning calorimeter, ultrasonic pulse echo technique, scanning electron microscopy, and transmission electron microscope. The optical properties of the obtained nanocomposites were shown to depend on zinc oxide particle size and content. The nanocomposite containing zinc oxide nanoparticles with an average particle size of 25.22 nm after calcination at 350 C was found to have the most optimal optical properties, namely high-visible light transparency and high-UV light shielding efficiency, which are desirable for many important applications.

“…Nanocomposites are a special class of materials having unique physical properties and wide application potential in diverse areas. [6][7][8][9] During the past years, many works have been carried out on the elaboration of nanocomposites system by embedding of inorganic particles into polymeric matrix, [10][11][12][13][14][15][16] affording a new class of polymeric materials which combine the properties of inorganic particles with the processability and flexibility of organic polymer matrix. Novel properties of nanocomposites can be obtained by successfully imparting the characteristics of parent constituents to a single material.…”

Zinc oxide (ZnO) is a very important compound used in several industries. We synthesized ZnO with different particle sizes and it was incorporated in high-density polyethylene (HDPE) matrix. The resulting nanocomposites were characterized using thermal, physical, and morphological techniques. The mechanical properties of the nanocomposites were also assessed. The nanocomposites were studied for their ultraviolet (UV) absorption properties and were shown to have very good spectral as well as mechanical properties which make them a perfect candidate for applications where UV absorption is essential for example food packing, UV shields, and many other applications.

“…Most recently, the double‐layer polymer shells were fabricated from the nanoparticle surfaces to improve their chemical and/or physical properties. Yu et al prepared the titanium dioxide inorganic core and polymer shell poly(styrene‐ co ‐divinylbenzene)‐methacrylic acid (P[(St‐ co ‐DVB)‐MAA])25 and poly(methyl methacrylate‐ co ‐ethylene glycol dimethacrylate)‐methacrylic acid (P[(MMA‐ co ‐EGDMA)‐MAA])26 composite particles by two‐step dispersion polymerization. Wang et al reported the preparation of the novel core (PBA/OMMT)–shell (PS) structured complex by γ‐ray radiation emulsion polymerization of styrene with poly (butyl acrylate) (PBA) and the intercalated or exfoliated organophilic montmorillonite (OMMT) as seeds 27…”

Attapulgite needle encapsulated with doublelayer polymer shell (ATP@DP) were prepared by the soapless seeded emulsion polymerization of the second monomer styrene in the dispersion of the attapulgite needle encapsulated with poly(methyl methacrylate) (ATP@PMMA), which was also conducted by the soapless seeded emulsion polymerization of the first monomer methyl methacrylate with the cetyltrimethylammonium bromide (CTAB) modified attapulgite needle (org-ATP) as seeds. The different morphologies of ATP, ATP@PMMA particles, and ATP@DP particles were characterized by transmission electron microscopy, and the encapsulation mechanism was also discussed.
