“…The synthesis and characterisation of methyl methacrylate-ethyl acrylate and styrene-ethyl acrylate copolymers were described in detail in our previous paper [28]. Briefly, all polymers were obtained in an emulsion polymerization process using a cationic surfactant, cetyltrimethylammonium bromide (CTAB) as an emulsifier and either sodium persulphate, Na 2 S 2 O 8 or (2,2 -azobis (2-methylpropionamidine) dichloride, AAPH, as an initiator (referred to as "anionic" and "cationic", respectively).…”

“…Subsequently, the overnight cultures were diluted in fresh media to obtain the required concentration of colony forming units per mL (CFU•mL −1 ). Antimicrobial tests were performed using the "dry film method" as described in our previous paper [28]. First, the 100 µL portions of each polymer were spotted on the bottom of a sterile Petri dish (Bionovo, Legnica, Poland) and left at room temperature to dry for three days.…”

“…The positive charge was introduced by employing a cationic surfactant, cetyltrimethylammonium bromide (CTAB) as an emulsifier. The surface charge brought by CTAB was maintained even after extensive dialysis and provided antibacterial activity against Gram-negative (E. coli), Gram-positive (S. aureus, B. subtilis) bacteria and yeast (C. albicans) [28]. In the present contribution we describe an extension of the previous study, by analysing compatibility of the positively charged latexes with two model inorganic particles used as fillers and pigments in real water-borne paints: CaCO 3 and TiO 2 .…”

Increasing antibiotic resistance of several pathogenic microorganisms calls for alternative approaches to prevent spreading of bacterial diseases. We propose to employ for this purpose coatings obtained from positively charged latex dispersions. In this contribution we characterize aqueous mixed dispersions containing TiO2 or CaCO3 and methyl methacrylate-ethyl acrylate or styrene-ethyl acrylate copolymers synthesized using a cationic surfactant, cetyltrimethylammonium bromide as an emulsifier. Particle size, electrokinetic (ζ) potential of the mixed dispersions and the resulting thin films, as well as antimicrobial properties of the latter are described. The TiO2 and CaCO3 dispersions were stabilised with polyethyleneimine (PEI) and optimum pH for the mixed dispersions were chosen on the basis of ζ-potential measurements. For TiO2, the maximum ζ = +35 mV was found at pH 7.5, and for CaCO3, pH was set at 8.2 (ζ = +38 mV), to prevent its dissolution. In most 1:1 mixtures of TiO2 or CaCO3 with the cetyltrimethylammonium bromide (CTAB)-stabilised latex dispersions, two distinct particles populations were observed, corresponding to the bare latex and bare TiO2 or CaCO3 fractions. Films made of the mixed dispersions remained positively charged and showed antimicrobial activity similar or reduced with respect to the bare polymer films.

A wreaking havoc condition in current urges the use of antimicrobial materials at its maximum. The various sectors such as health‐care institutions, food packaging, textile industry, water‐purification system, and so on, have high demand for the use of antimicrobial materials and paint industry is one amongst them. Since millennium, paints has been used to decorate the surroundings we live in. The transformation of use of paints can be observed from prehistoric to modern day walls as a protective and a feature enhancing substance. The paints with antimicrobial property have experienced tremendous growth to improve microbial quality in residential, commercial, institutional and industrial applications for its need to control the microbial growth which prevents the spread and reduces the risk of infections. Antimicrobial paints kill microorganisms upon contact while still retaining their durability which withstands the inevitable deterioration of paints. Antimicrobial paint additives can be easily and cost‐effectively manufactured into all types of solvent‐based, water‐based, liquid, oil or powder paints and coatings. This review provides an insight on the use of polymers in developing antimicrobial paints and their use as binder, emulsifier, latexes, varnishes, and so on, against various pathogenic waterborne and airborne microorganisms. The literature also defines the replacement of solvent‐based paints to water‐based paints which are environmentally friendly and act as good filling binder.
