In this article, the titanium‐oxo cluster containing bromine had been prepared by solvothermal synthesis, which was used to initiate the atom transfer radical polymerization of butyl methacrylate in order to obtain organic–inorganic hybrid materials. The structures and compositions of titanium‐oxo cluster and its hybrid materials were characterized by X‐ray photoelectron spectroscopy (XPS), 1H nuclear magnetic and infrared spectra tests. The hybrid materials with different molecular weights were dissolved in tetrahydrofuran and coated on the surface of polyethylene terephthalate (PET) film, which was used to study the surface properties. Compared with 89.7% light transmittance of the pure PET film, the light transmittance of the modified films was up to 93.3%. Meanwhile, the water contact angles of the modified films also significantly increased. It would be conducive to the self‐cleaning of the film surface. The coatings prepared by the static respiration diagram method had better hydrophobic effect and show the performance of light scattering. All of that could be proved through the scanning electron microscope (SEM) images. The elastic modulus and hardness of hybrid materials also change with the increase of molecular weight. In addition, the Tg of the hybrid materials increased, which means they have better thermal stability than that of Polybutylmethacrylate (PBMA).

A versatile imaging‐based method is presented for quantifying the transparency of materials based on “illumination diffusion” (ID), representing scattering‐ and refraction‐induced change in the spatial distribution of transmitted light intensity. Samples are backlit through a graticule mask, with analysis performed by comparative evaluation of graticule images recorded as‐is and viewed through a sample, mimicking visual perception. ID‐haze is quantified as the reduction of contrast, while ID‐sharpness is derived from imaged knife‐edge acuity. Measurements are performed for diverse materials, including clarified polyolefins, silica‐filled amorphous polymers, semicrystalline films, and etched polymer sheets. Comparisons with the respective haze and clarity values obtained using a common ASTM D1003 haze‐meter are made in terms of their quantitative correlation and suitability for applications. In particular, unlike conventional instruments, ID‐based analysis captures the variation of transparency with sample‐to‐object “airgap” distance. Gratifyingly, ID‐haze generally features a one‐to‐one correlation with standard ASTM haze, when determined at a specific distance. The presented method also enables sensitive detection of local defects—differentiating them from large‐area characteristics—and accurately extracts the contribution of luminescence to loss of transparency. ID‐based method therewith offers unique opportunities for application‐ and airgap‐specific transparency analysis, and advanced options for optical process‐ and quality control.

Strategies to incorporate a fluorinated acrylate monomer into polymer particles: from particle morphology to film morphology and anticorrosion properties

et al. 2022

Four strategies to incorporate a fluorinated monomer (perfluoro octyl acrylate, POA) into a waterborne polymeric dispersion are investigated. Due to the very low water solubility of the POA monomer, three of the strategies use miniemulsion droplets containing the whole POA monomer in the initial charge. The rest of the comonomers of the formulation (methyl methacrylate, MMA, and n-butyl acrylate, BA) are partially incorporated in the initial miniemulsion or fed to the reactor as a preemulsion. In the fourth strategy, a conventional seeded semibatch emulsion polymerization is carried out using cyclodextrin in the seed and feeding the POA/MMA/BA preemulsion to the reactor. Each process strategy led to a distinct particle morphology and hence a particular film morphology. We found that the strategy that produced core–shell particles with the core composed by pure polyPOA yielded the films that showed the best corrosion protection as measured in salt-spray test (1200 h standing without damage).
