“…The spectra of both materials, that is, the polymeric matrix and the resin, are well merged in the studied formulations. This phenomenon suggests a good chemical interaction such as the formation of hydrogen bonds between each resin and the components of the polymeric matrix, particularly in the case of pentaerythritol esters of GR, as it has been previously observed when using GR derivatives as polymer additives …”

The effect of three additives derived from pine resin, namely, gum rosin (GR) and two pentaerythritol ester of GR, Lurefor (LF) and Unik Tack (UT), in 5, 10, and 15 wt %, on the properties of Mater‐Bi, based on plasticized starch, poly(butylene adipate‐co‐terephthalate), and poly(ε‐caprolactone) (PCL), obtained by injection molding processes, was studied. The mechanical, microstructural, and thermal properties were evaluated. LF had a cohesive behavior with the components of Mater‐Bi, increasing the toughness of the material up to 250% accompanied by an increase of tensile modulus and tensile strength. UT had an intermediate behavior, conferring cohesive and plasticizing effects, allowing an increase of 105% in impact resistance. GR had a more marked plasticizing effect. This allows processing temperatures of about 50 °C lower than those used for neat Mater‐Bi. In addition, an increase of the elongation at break, toughness, and impact resistance in 370, 480, and 250%, respectively, was achieved. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.

“…Peaks at 1450 cm −1 are due to CH 2 bending mode, at 1362 cm −1 are due to CH 3 bending, while those at 1225 and 1215 cm −1 are due to the CO stretching of acid groups. Finally, some peaks from 1000 to 650 cm −1 correspond to CH out of plane bending …”

“…Rosin derivatives may serve as alternatives to petroleum‐based aromatic compounds or cycloaliphatic compounds that are generally used to modify polymers and improve their thermal and mechanical properties . The hydrogenated phenanthrene ring, as a characteristic functional group of rosin, significantly affects the hydrophobic and thermomechanical properties of polymers . Moreover, as the primary structural unit of target polymer, the huge hydrogenated phenanthrene ring structure can effectively block the winding of molecular segments, which increases the intermolecular spacing and free volume in polymer molecules .…”

A rosin‐based monomer with thermally crosslinkable benzocyclobutene groups was synthesized in this study. The structure of the monomer was examined using mass spectroscopy, Fourier transform infrared spectroscopy, and nuclear magnetic resonance spectroscopy. An amorphous crosslinked network with dielectric constant of 2.71 and dielectric loss of 0.0012 at 30 MHz was formed when the monomer was polymerized at high temperature (> 200 °C). The polymer film exhibits surface roughness (Ra) of 0.337 nm in a 5.0 × 5.0 μm2 area and the water contact angle of 110°. In addition, results from thermogravimetric analysis indicate that the polymer has T5% = 402 °C, and differential scanning calorimetry measurements show that the glass transition temperature is at least 350 °C. Results from nanoindentation tests show that the hardness and Young's modulus of the polymer are 0.418 and 4.728 GPa, respectively. These data suggest that this new polymer may have potential applications in electronics and microelectronics. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2020, 137, 48831.

Green synthesis of strontium nanoparticles self‐assembled in the presence of carboxymethyl cellulose: an in vivo imaging study

et al. 2019

View full text Add to dashboard Cite

Carboxymethyl cellulose (CMC) is one of the main derivatives of cellulose and is used as a drug carrier for hydrophobic and hydrophilic drugs, imaging in vivo, and biological applications. Encapsulation is a technology in which target compounds are coated with wall compounds to form microcapsules. This study reports a new chemical processing wet method for precipitation and encapsulation of strontium nanoparticles (Sr NPs) within CMC structures using a sonochemical method. Preparation parameters such as microwave power and irradiation time as well as morphology and particle size of Sr NPs were also investigated. Products were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, thermogravimetric analysis and atomic force microscopy. In this study, CMC was used as a biological stabilizer in a retentive phase to encapsulate Sr NPs. For the first time, Sr NPs were synthesized using CMC in a cost-effective, simple, fast, micellation-assisted, ultrasound method. Sr NPs were encapsulated in green capping agent structures of either 1%, 2% or 3% weight to provide an efficient optical nanostructure with a high yield at wavelengths 200-700 nm for use in in vivo imaging studies.
