“…Figure 2 (a) shows the XRD results for the r-ABS and its composites with 3% of both TiO 2 . For the r-ABS, it is visible that there are peaks that are not present in the neat non-recycled ABS, according to literature [15]. It is expected, though, as the r-ABS contains a vast number of additives in its composition, resulting in those peaks.…”

The increasing concern about plastic disposal and its impact on the environment has led to the necessity to reuse these materials, completing their life cycle within the circular economy mentality: production, use, recycling, and reuse. One of the residues that has caused great concern is the so-called waste electrical and electronic equipment (WEEE).The reintroduction of a recycled material back into the market requires some type of modi cation since the recycling process lightly alters the general properties of those materials. In this work, we studied the recycling of ABS -one of the polymers most found in waste electrical and electronic equipment -and its modi cation through commercial titanium dioxide (TiO 2 ) and modi ed with peroxide groups (TiO 2 -OPM). The TiO 2 -OPM have interesting electrical properties due to their lower band gap values, which results in them being good candidates for the modi cation of recycled polymers for WEEE applications.For this, different percentages of particles were incorporated into ABS from the electro-electronic industry. Aspects of degradation, rheology, and antistatic were analyzed. A good interaction between the particle and polymer is observed, especially for those modi ed with the peroxo group. Nevertheless, it is observed that this modi cation promotes a reduction in the initiation of exothermic reactions for the butadiene phase, which seems to be a positive aspect because it preserves the acrylonitrile-styrene phase. The interaction is observed rheologically, indicating the formation of a percolated network that favors antistatic characteristics, even with a reduced amount of TiO 2 -OPM. This work presents a framework for the development of more sustainable materials with concepts of a circular production system.

“…The FTIR technique is an analysis of great interest in evaluating the chemical modification of polymers, as demonstrated in the literature [49,50]. In Figure 4, the prominent PHB absorption bands are observed before and after chemical modification with styrene (St.), maleic anhydride (MA), DCP, and Sn(Oct) 2 .…”

In this work, polyhydroxybutyrate (PHB) was maleic anhydride (MA)-grafted in the molten state, using dicumyl peroxide (DCP) as a reaction initiator. Tin(II) 2-ethylhexanoate (Sn(Oct)2) and styrene monomer (St.) were used to maximize the maleic anhydride grafting degree. When PHB was modified with MA/DCP and MA/DCP/Sn(Oct)2, viscosity was reduced, suggesting chain scission in relation to pure PHB. However, when the styrene monomer was added, the viscosity increased due to multiple grafts of MA and styrene into the PHB chain. In addition, the FTIR showed the formation of a new band at 1780 cm−1 and 704 cm−1, suggesting a multiphase copolymer PHB-g-(St-co-MA). The PHB (MA/DCP) system showed a grafting degree of 0.23%; however, the value increased to 0.39% with incorporating Sn(Oct)2. The highest grafting efficiency was for the PHB (MA/DCP/St.) system with a value of 0.91%, while the PHB (MA/DCP/St./Sn(Oct)2) hybrid mixture was reduced to 0.73%. The chemical modification process of PHB with maleic anhydride increased the thermal stability by about 20 °C compared with pure PHB. The incorporation of 0.5 phr of the Sn(Oct)2 catalyst increased the efficiency of the grafting degree in the PHB. However, the St./Sn(Oct)2 hybrid mixture caused a deleterious effect on the maleic anhydride grafting degree.

Nanometer Zinc oxide (nano ZnO) composites are widely used in the packaging industry due to their excellent antibacterial properties. In this study, low-doped (0.2%) and high-antibacterial (99.9%, R = 6.9) nano ZnO composites with different matrices were prepared using a masterbatch blending method. To investigate the effect of different matrices on antibacterial properties, we decreased the solid content of nano ZnO to 0.05% and prepared antibacterial lms by melt-blending with ethylene vinyl acetate copolymer (EVA), polyole n elastomer (POE), linear low-density polyethylene (LLDPE), high-density polyethylene (HDPE), and amorphous polymer polycarbonate (PC). The results showed that low melt strength and high crystallinity would decrease the antibacterial activity of the composite. At room temperature, the PC with a frozen molecular chain can hinder the migration of small molecules, thereby reducing antibacterial activity. Polar ZnO is more compatible with polar vinyl acetate (VA), leading to the hindered surface migration of ZnO and reduced antibacterial activity. Most importantly, low crystallinity does not necessarily lead to a reduction in barrier properties. The dense and rich layered arrangement of polyole n elastomer (POE) increases its ability to impede the migration of nano ZnO, thereby signi cantly reducing its antibacterial effectiveness. A concentration of 0.05% ZnO/linear low-density polyethylene (LLDPE) exhibited an antibacterial rate of up to 99.3%. Additionally, adding a small amount of nano ZnO improves the tear resistance of antibacterial composite materials. This study provides a theoretical basis for the preparation of low doping, high antibacterial and excellent comprehensive performance.
