“…In the bottom-up process of the BF mechanism, the stage at which there is an interfacial interaction of water droplet and polymer solution can be applied for the site-selective functionalization. Applying this phenomenon, Huh et al recently introduced a modified BF method, called the reactive BF (rBF) method, for the single-step fabrication of pore-selective functionalized films by accompanying an interfacial chemical reaction during the BF process [ 98 , 109 , 110 , 111 , 112 , 113 ]. For this method, a solvent-soluble reactant is added to the hydrophobic polymer solution, and a water-soluble counter reactant is added to the water used for humid conditions.…”

“…When the polymer solution containing functionalizing reactant is cast under humid conditions containing counter reactant, a chemical reaction happens at the aqueous droplet/polymer solution interface and the product is formed in the pore of HCP film as a coating, summarized in Table 3 [ 109 , 110 , 111 , 112 ]. The benefit of this approach is that any material, either organic [ 109 , 110 , 111 , 112 ] or inorganic [ 113 ], can be functionalized by this method in one single step. Male et al fabricated pore functionalized polyaniline (PANI) HCP porous films by in-situ polymerization via the BF method [ 110 ].…”

“…As the porous films are composed of the polymer framework and pores, their use can be applicable to frameworks and pores [ 121 ]. Compared with the vigorous progress of the framework, the applications of pores is less reported, acting as secondary templates [ 105 , 114 , 122 ], selective antibacterial surfaces [ 5 , 113 , 123 ], catalysis [ 70 , 71 ], selective cell culturing [ 5 , 123 ], drug capture and release [ 95 , 115 ], or in protein recognition [ 87 , 89 ], as shown in Figure 21 . Thus, how to develop the new functions of the cavities becomes very meaningful, which will bring new vitality to the field of porous films.…”

Recent developments in the field of the breath figure (BF) method have led to renewed interest from researchers in the pore-selective functionalization of honeycomb-patterned (HCP) films. The pore-selective functionalization of the HCP film gives unique properties to the film which can be used for specific applications such as protein recognition, catalysis, selective cell culturing, and drug delivery. There are several comprehensive reviews available for the pore-selective functionalization by the self-assembly process. However, considerable progress in preparation technologies and incorporation of new materials inside the pore surface for exact applications have emerged, thus warranting a review. In this review, we have focused on the pore-selective functionalization of the HCP films by the modified BF method, in which the self-assembly process is accompanied by an interfacial reaction. We review the importance of pore-selective functionalization, its applications, present limitations, and future perspectives.

“…The antimicrobial activities of nanocomposites, for instance, as synthesized with Ag/polyvinylpyrrolidone, were tested against various bacterial and fungal strains and a strong antimicrobial property was discovered [31]. Recently, researchers have applied various strategies to improve antibacterial and antibiofilm properties, including the direct modification of membrane material [24,32], or blending or coating with bioactive or chemical moieties having antibacterial properties such as metal ions or nanoparticles (NPs) [33,34]. A few previous investigations have also reported the antibacterial action of similar composites, such as Bi 2 WO 6 /Ag [35] and BWO/GO [36] due to photogenerated oxyradicals, which are responsible for the destruction of the bacterial structure.…”

Bismuth Vanadate Decked Polyaniline Polymeric Nanocomposites: The Robust Photocatalytic Destruction of Microbial and Chemical Toxicants

et al. 2023

Functional materials have long been studied for a variety of environmental applications, resource rescue, and many other conceivable applications. The present study reports on the synthesis of bismuth vanadate (BiVO4) integrated polyaniline (PANI) using the hydrothermal method. The topology of BiVO4 decked PANI catalysts was investigated by SEM and TEM. XRD, EDX, FT-IR, and antibacterial testing were used to examine the physicochemical and antibacterial properties of the samples, respectively. Microscopic images revealed that BiVO4@PANI are comprised of BiVO4 hollow cages made up of nanobeads that are uniformly dispersed across PANI tubes. The PL results confirm that the composite has the lowest electron-hole recombination compared to others samples. BiVO4@PANI composite photocatalysts demonstrated the maximum degradation efficiency compared to pure BiVO4 and PANI for rhodamine B dye. The probable antimicrobial and photocatalytic mechanisms of the BiVO4@PANI photocatalyst were proposed. The enhanced antibacterial and photocatalytic activity could be attributed to the high surface area and combined impact of PANI and BiVO4, which promoted the migration efficiency of photo-generated electron holes. These findings open up ways for the potential use of BiVO4@PANI in industries, environmental remediation, pharmaceutical and medical sectors. Nevertheless, biocompatibility for human tissues should be thoroughly examined to lead to future improvements in photocatalytic performance and increase antibacterial efficacy.

We have fabricated poly(ε-caprolactone) (PCL) films with flat and honeycomb-patterned (HCP) structures to coat polyaniline (PANI) on the film surface. In addition, the effect of chemical modification of PANI by sulfuric acid (H2SO4) was also studied for antibacterial activity. The flat and HCP PCL films were obtained by simple evaporation of the solvent and via the breath figure (BF) method, respectively. The morphology and chemical composition of PANI coated on the film surface were evaluated by scanning electron microscopy (SEM) and X-ray spectroscopy (EDX). Fourier transform infrared spectroscopy (FT-IR) and thermogravimetric analyses (TGA) were obtained to identify the PANI coating. The wettability and conductivity of the films were also measured. Applicational aspects were evaluated by assessing antibacterial and antibiofilm activity against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). The EDX, TGA, and FT-IR findings indicated chemical modification of PCL film by PANI and H2SO4. The conductivity of the films was increased by the coating of PANI to the patterned surface and additionally increased by the chemically modified PANI. The antibacterial activity was 69.79%, 78.27%, and 88% against E. coli, and 32.73%, 62.65%, and 87.97% against S. aureus, for flat PANI, HCP PANI, and H2SO4-treated HCP films, respectively. Likewise, the PANI coated flat, HCP, and H2SO4-treated HCP films inhibited E. coli biofilm formation by around 41.62%, 63%, and 83.88% and S. aureus biofilm formation by 17.81%, 69.83%, and 96.57%, respectively. The antibacterial activity of the HCP film was higher than that of flat PANI films, probably due to the higher coating of PANI on the HCP surface. Moreover, sulfonation of the HCP film with H2SO4 might have improved the wettability, thereby enhancing the antibacterial and antibiofilm properties. Our results showed that topographical changes, as well as doping, offer simple and cost-effective ways to modify the structural and functional properties of films.
