Influence of Varied Fluorine Contents on Long-Term Storage Stability of Polyacrylate Nanoparticles and Film Properties

Abstract

Polyacrylate nanoparticles are widely applied and typically prepared by many polymerization methods. However, poor long-term storage stability of nanoparticles limited their use, so some methods are carried out to overcome it. In this paper, we investigated a series of fluorinated polyacrylate nanoparticles to improve the long-term storage stability of polyacrylate nanoparticles. We found that increasing fluorine content resists the aggregation of nanoparticles during long-term storage. Furthermore, a higher content of fluorine can improve the hydrophobicity of latex polyacrylate film and increase the refractive index of latex polyacrylate film. The properties of the polyacrylate nanoparticles and latex film can thus be controlled by changing fluorine contents, which in turn provides key insights into the design of functional polymer material.

Imidazolium-Based Ionic Liquid-Assisted Silver Nanoparticles and Their Antibacterial Activity: Experimental and Density Functional Theory Studies

“…The mean hydrodynamic sizes for the prepared Ag-[EMIM]­[MS] NPs, Ag-[BMIM]­[OTf] NPs, and Ag-[BMIM]­[TFSI] NPs were 278, 316, and 279 nm, respectively, with polydispersity index values between 0.34 and 0.39 (Figure ). As compared with the Ag-[BMIM]­[OTf] NPs, the Ag-[BMIM]­[TFSI] NPs with a higher fluorine content displayed a smaller particle size in accordance with the previous literature . The ζ-potential values for these silver NPs at various ILs were negative in the range of −20 to −43 mV.…”

Nanoparticles as Anti-Microbial, Anti-Inflammatory, and Remineralizing Agents in Oral Care Cosmetics: A Review of the Current Situation

“…The stability of NPs, from synthesis to sterilization, storage processes, and use in biological environment, are also of interest regarding the availability to maintain nanosized distribution after synthesis and purification steps [19][20][21][22]. For example, consecutively to their synthesis and stabilization in a liquid environment, free drying or lyophilization, which is conventionally used to store NPs in a dried state, is well known to enhance more or fewer aggregation-irreversible mechanisms [23][24][25][26].…”

One‐pot construction of epoxy resin nanocarrier delivering abamectin and its efficacy on plant root‐knot nematodes

“…The regulation of mechanical properties was difficult due to the high surface energy and large surface area of nanocarriers 11 . The particle size of nanopesticides stored as nanoparticles or nanoemulsions easily increased due to Ostwald ripening, and they were liable to aggregate and flocculate during long‐term storage 12–14 . Nanocarriers with core‐shell structures and mesoporous structures could reduce the direct contact between particles and avoid Ostwald ripening to a certain extent.…”

“…11 The particle size of nanopesticides stored as nanoparticles or nanoemulsions easily increased due to Ostwald ripening, and they were liable to aggregate and flocculate during long-term storage. [12][13][14] Nanocarriers with core-shell structures and mesoporous structures could reduce the direct contact between particles and avoid Ostwald ripening to a certain extent. However, most of the reported nanoparticles were stored after drying, such as the widely researched mesoporous silica and polylactic acid nanocarriers.…”
