Abstract
Along with society’s progress, high-quality coatings are widely used. Although fluorinated polymers were successfully prepared by semicontinuous emulsion polymerization with surfactants, chlorotrifluoroethylene (CTFE), and acrylate monomers, the optimization collocation of surfactants still has room for improvement. The traditional emulsifiers are physically absorbed onto the surface of latex particles. The latex film generated by latex particles is unstable in water, which limits its application. Herein, a novel series of cationic quaternary ammonium polymerizable surfactant was selected because it can react with CTFE and acrylate monomers and can become a part of the polymers. We also studied the effects of emulsifier type on resultant emulsion properties. In addition, wonderful weatherability, water resistance, and antibacterial and antifouling of the multifunctional fluorinated films were observed, which would open up a bright future for coating industries.
Highlights
Fluoropolymers have recently attracted considerable attention due to their excellent chemical resistance, low dielectric constant, good hydrophobicity/oleophobic, and weatherability [1,2,3,4], which are extensively used in the fields of microelectronic devices, coatings, optical devices, finishing agents, and biomedical implants [5,6,7,8]
There is no denying that pre-emulsion stability plays an important role in polymerization progress
Given that gaseous CTFE need to emulsify under high pressure, for safety purposes, only liquid monomers such as butyl acrylate (BA), vinyl acetate (VAc), and Veova10 were explored
Summary
Fluoropolymers have recently attracted considerable attention due to their excellent chemical resistance, low dielectric constant, good hydrophobicity/oleophobic, and weatherability [1,2,3,4], which are extensively used in the fields of microelectronic devices, coatings, optical devices, finishing agents, and biomedical implants [5,6,7,8]. Several factors could be responsible for this: (1) the higher crystallinity leads to its weak organic solubility; (2) because of its high melting point (220°C), the manufacturing process will cause additional loss of energy; and (3) poor adhesion brings about a big discount of the film forming ability. To circumvent these obstacles and cut the cost, the copolymerization of chlorotrifluoroethylene (CTFE) with other acrylate monomers seemed to be an ideal solution [1, 10,11,12].
