“…The polydispersity indexes (PdI) are below 0.2, which indicated that products had satisfactory stability and good dispersibility. The smaller the value of PdI, the better the homogeneity of the dispersion [36]. The stability of the dispersions was assessed by measuring the Z potential of each WPUD.…”

Waterborne polyurethane-urea dispersions (WPUD), which are based on 100% bio-based semi-crystalline polyester polyol and isophorone diisocyanate, have been successfully synthesized and doped with single-walled carbon nanotubes (SWCNT) to obtain a finishing agent that provides textiles with multifunctional properties. The chemical structure of WPUD has been characterized by Fourier-transform infrared spectroscopy (FTIR) and nuclear magnetic resonance (NMR). The thermal properties have been evaluated by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and dynamic mechanical thermal analysis (DMTA). Mechanical properties have been studied by tensile stress–strain analysis. Moreover, the particle size, particle size distribution (PSD), and stability of developed waterborne dispersions have been assessed by dynamic light scattering (DLS), Z-potential, and accelerated aging tests (analytical centrifugation). Subsequently, selected fabrics have been face-coated by the WPUD using knife coating method and their properties have been assessed by measuring water contact angle (WCA), water column, fabric stiffness, and air permeability. The electrical conductivity of textiles coated with SWCNT-doped WPUD has been evaluated by EN 1149 standard. Finally, the surface morphologies of uncoated and coated fabrics have been studied by scanning electron microscopy (SEM). All of the synthesized polyurethane-ureas provide the coated substrates with remarkable water-repellency and water column, being therefore a more sustainable alternative to waterproof coatings based on fluoropolymers, such as PTFE. The additivation of the polymeric matrices with SWCNT has led to textile coatings with excellent electrical conductivity, maintaining water column properties, giving rise to multifunctional coatings that are highly demanded in protective workwear and technical textiles.

“…It is worth noting that long perfluoro alkyl reagents (C8 and larger) are under scrutiny and strict regulations are forecast for a near future. Nonetheless, they have been extensively investigated to produce materials with superhydrophobic or superoleophobic properties and they have been reported in applications that include self-cleaning coatings, anti-corrosion coatings, anti-icing coatings, surface coatings for textiles, paper, and leather [7,11,19,[27][28][29][30][31]. In particular, copolymers with long side chains composed of a perfluoroakyl group (-C n F 2n + 1 ) have received a great deal of attention.…”

Strategies to incorporate a fluorinated acrylate monomer into polymer particles: from particle morphology to film morphology and anticorrosion properties

Four strategies to incorporate a fluorinated monomer (perfluoro octyl acrylate, POA) into a waterborne polymeric dispersion are investigated. Due to the very low water solubility of the POA monomer, three of the strategies use miniemulsion droplets containing the whole POA monomer in the initial charge. The rest of the comonomers of the formulation (methyl methacrylate, MMA, and n-butyl acrylate, BA) are partially incorporated in the initial miniemulsion or fed to the reactor as a preemulsion. In the fourth strategy, a conventional seeded semibatch emulsion polymerization is carried out using cyclodextrin in the seed and feeding the POA/MMA/BA preemulsion to the reactor. Each process strategy led to a distinct particle morphology and hence a particular film morphology. We found that the strategy that produced core–shell particles with the core composed by pure polyPOA yielded the films that showed the best corrosion protection as measured in salt-spray test (1200 h standing without damage).

“…Over the past decade, a variety of polymeric nanoparticles have been reported in the literature, including polyolefins [11], polyesters [12], polyurethanes [13], polyaryletherketones [14], polysaccharide [15], and polyacrylates [16] as well as their copolymers [16]. Polymeric nanoparticles and their films possess prominent economic value, which are applied for finishing agent [17,18], anticorrosion coating [19], photoresponsive material [20], dielectrics, and adhesives [21].…”

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.
