“…FTIR was employed to verify the interaction between the PEW‐g‐MAH and CPO. According to the previous reports, 35 CO vibration peaks at 1860 and 1780 cm −1 in the IR spectrum of PEW‐g‐MAH were weakened after saponification, while two new characteristic absorption peaks appeared at 1571 and 1470 cm −1 (Figure 3d), which were attributed to the COO − stretching vibration after the saponification of PEW‐g‐MAH to form carboxylate. It is found that CO vibration peaks at 1860 and 1780 cm −1 were further weakened, and the relative intensity and width of peaks that appeared at 1571 and 1470 cm −1 became stronger and wider after the incorporation of CPO.…”

“…TEM and FTIR also confirmed the size of our synthesized CPO (<2 nm), which is consistent with previous reports (Figure S1c). [34][35][36] More interestingly, if we replace the oligomer with SiO 2 nanoparticles, the average particle size of the emulsion increases rather than decreases (382 nm), and the stability of the emulsion deteriorates (Table S1).…”

Polyethylene waxes are low molecular weight polyolefin synthetic waxes with outstanding mechanical properties, lubricating performance, and chemical stability, which are widely used in various industrial fields. The nonpolar nature of polyethylene waxes leads to low surface energy and poor compatibility with polar materials, which limits their development applications. Therefore, developing composites with better mechanical properties is essential to overcome this drawback. In this work, calcium phosphate oligomers (CPO) are employed to stabilize nano‐emulsions of polyethylene wax modified with maleic anhydride. The emulsification of emulsions was investigated under different NaOH dosages, temperatures, emulsification times, and rotational speeds. The prepared emulsions are used as additives in polyurethane coatings and starch slurries. The CPO can reduce the particle size of the nanohybrid emulsions and greatly improve the abrasion resistance of some polymer films as additive agents. The organic and inorganic units were homogeneously combined with properties of a complete and continuous organic–inorganic network. The emulsions exhibit ultra‐high abrasion resistance when applied to polyurethane coatings and starch pastes, broadening their range of applications.

In this study, functionalization of low-molecular-weight polyethylene by melt grafting of maleic anhydride was investigated. The results reveal that initiator concentration, reaction time and temperature have the greatest influence on the graft degree. Structure of maleic anhydride grafted low-molecular-weight po-lyethylene was proven by FTIR, DTA and XRD me-thods. The grafted low-molecular-weight polyethylene has a potential application as a compatibilizer for mate-rials based on polyethylene compounds.

Antimicrobial polyethylene wax (PEW) emulsions, prepared by emulsifying polyethylene wax grafted with polyhexamethylene guanidine hydrochloride (PEW-g-PHGH), were used as wet-end additives or coating materials for fabricating hydrophobic and anti-mold hand-sheets or paper. To obtain PEW-g-PHGH, maleic anhydride (MAH) was adopted as a bridging agent. The melt or solution grafting of MAH to PEW was performed to achieve the appropriate grafting degree and grafting efficiency. The resulting PEW-g-PHGH was emulsified using a homogenizer by means of surfactants, and the resulted emulsions were characterized in terms of particle size, zeta potential, charge density, minimal inhibitory concentration (MIC), and adsorption capacity. After that the hydrophobicity of emulsion treated hand-sheets was determined by measuring water contact angle (WCA). The morphology of the handsheets treated by the emulsion was revealed using scanning electron microscope (SEM) and atom force microscope (AFM). Finally, the antimicrobial properties of the emulsion treated hand-sheets were investigated by anti-mold tests against Aspergillus niger and Chaetomium globosum. Results indicated that the PEW-g-PHGH emulsions exhibited good stability, high fiber adsorption capacity, and antimicrobial activity. The WCAs of the treated hand-sheets reached 82 -140 with 80%$99.9% growth inhibition against fungi.
