“…Polyethylene glycol (PEG) is a polymer of ethylene glycol containing α,ω-bis-terminal hydroxyl groups with excellent wettability, moisture retention, dispersibility, biocompatibility, and ease of chemical modification. , Polyethylene glycol chain segments are incorporated into polyesters to form copolymers, which are widely used because of the good compatibility between the chain segments. For the hydrophilic modification of polyester materials, Ji et al prepared polyethylene terephthalate (PET)–PEG/zinc oxide-modified nanocomposites by introducing stearic acid (SA) into zinc oxide to prepare a highly active nanocatalyst on the surface. SA was introduced into the surface of zinc oxide and its surface properties were changed from hydrophobic to hydrophilic.…”

Poly(butylene adipate-co-terephthalate) (PBAT) is the most extensively researched and developed biodegradable material. Its application in the production of garments, packaging, and films is limited due to the lack of polar groups on its surface. To address the issue of insufficient hydrophilicity of PBAT, this paper presents modified PBAT that incorporates a hydrophilic chain segment (polyethylene glycol, PEG) during the polycondensation process. Regenerated bis(hydroxybutyl)terephthalate (BHBT), a precursor material for the synthesis of biodegradable PBAT, was produced through the chemical alcoholysis of poly(butylene terephthalate) (PBT). Hydrophilic PBAT was then prepared by condensation polymerization with recycled BHBT, BHAT (dihydroxybutyl adipate), and PEG. It has been demonstrated that the successful doping of hydrophilic PEG into the main chain of PBAT improves its hydrophilicity. This leads to a decrease in elongation at the break and tensile strength. Additionally, the contact angle decreases to 46.71°, while the surface free energy (γ s ) increases to 42.99 mJ/m 2 . Hydrophilic PBAT copolyesters exhibit an increase in gas permeability, with the highest permeability coefficient of water vapor (OSF WV = 1.358). In the visible light range of 400−800 nm, PBAT copolyesters exhibit higher transmittance than PBAT materials, resulting in greater transparency. Additionally, R-PBAT has a higher loss modulus and energy storage modulus than the PBAT copolyester in the range of 0.1−100 rad/s. The inclusion of PEG chain segments enhances the melt fluidity of the PBAT copolyester, facilitating processing. While over the course of 30 days, the addition of PEG had an effect on the degradation rate of PBAT, which remained at 34.44%.

ZnO particles were synthetized by the sol–gel method and subsequent heat treatment of 400, 500 and 600 °C was applied. The nano ZnO particles were incorporated to the unsaturated polyester resin by solution blending at 0.05 wt % concentration. X-ray diffraction detected the formation of a wurtzite-like structure. Viscoelastic behavior of neat polyester and nanocomposites revealed the nano ZnO particles does not promote better mechanical properties because of a weak interaction and the glass transition temperature of the polyester was favored by the presence of a higher quantity of nano-size ZnO particles. Thermogravimetric analysis at 5, 10 and 20 °C/min allowed determining the degradation kinetic parameters based on the Friedman and Kissinger models for neat polyester and nanocomposites. Heating rates promoted an increase in the temperature degradation and the addition of ZnO particles promoted a catalyst effect that reduce the amount of thermal energy needed to start the thermal degradation.

“…ZnO is often used in various polymeric films, for the manufacture of the active antimicrobial packaging (Naveed ul Haq et al, 2017). The most common polymers / mixtures of polymers in which ZnO is used, in order to obtain thin films are, PET-poly(ethylene terephthalate) / PBS-poly(butylene succinate), co-polymer (Threepopnatkul et al, 2014), -PET/PEG -poly(ethylene glycol) (Ji et al, 2015), polyurethane -PU (Chen et al, 2013), cases -PP (Hadi et al, 2016), etc. The main problem in obtaining homogeneous composite materials is very difficult because ZnO possesses a large surface area and a surface energy increases, leading to an agglomeration in the matrix of copolymers / polymers, altering the physico-mechanical properties.…”

“…In order to reduce the agglomeration of ZnO in the polymeric matrix, it is necessary to modify its surface. The most used coupling agents are: oleic acid (Aysa et al, 2017), stearic acid (Ji et al, 2015), 3-aminopropyltrimethoxysilane -APTS, 3 -thiolpropyltrimethoxysilane -TPTS, (El-Nahhal et al, 2016;Lu et al, 2018), etc.…”

The aim of this study is to identify the optimal method of surface modification of ZnO nanoparticles in order to obtain a high deposition rate of the polydimethylsiloxane (PDMS) functionalizing agent. Thus, in order to identify the optimal route, the surface of ZnO nanoparticles were functionalized by 3 methods, ultrasonic, magnetic stirring and vacuum adsorption, followed by advanced powder characterization, FTIR, SEM, EDS, DSC-TG. The FTIR analysis recorded on the surface modified ZnO powder highlights the functional groups in the PDMS, regardless of the synthesis method, which confirms that the functionalization took place. However, based on the intensity of PDMS functional groups, it can be concluded that the highest deposition rate is obtained in the case of ultrasonography, followed by the magnetic stirring and vacuum adsorption method. This different deposition rate can be attributed to the fact that ultrasonication leads to ZnO particles being broken down into smaller particles, resulting in a higher contact surface with PDMS. The SEM image obtained on the commercial ZnO powder and the ZnO / PDMS powder, highlights their extremely varied morphology and demonstrates that the modification does not influence either the shape or size of the ZnO. EDS analysis confirms that functionalization took place due to the presence of the Si element alongside the other Zn and O major elements. The DSC-TG analysis obtained on the ZnO / PDMS powder indicated an organic mass loss, from the organosilane structure, of 5.51% in the range of 365-530°C. The results obtained provide the premise that these functionalized ZnO nanoparticles in addition to antibacterial properties will improve compatibility / dispersibility in various polymeric matrices.
