“…Among other photothermal polymers, polydopamine (PDA), the mussel-inspired polymer, stands out owing to its distinct physical properties in addition to its intrinsic photothermal capacity . PDA, synthesized by the oxidative self-polymerization of dopamine, has strong adhesive properties due to its catechol groups, which enable it to be coated to almost any kind of surfaces ranging from wood and oil droplets to polymers , for a wide variety of applications . Since the polymerization of dopamine occurs either on a substrate, resulting in PDA-coated surfaces, or via the aggregate formation, resulting in PDA particles, it is generally employed as a component in a hybrid system rather than as a monolithic, homogeneous polymer matrix in light-to-heat conversion systems. − PDA-containing polymeric composites have been typically prepared by either coating bulk polymeric material surfaces with PDA or incorporating PDA-functionalized nanoparticles into the polymer matrix and have been utilized in various applications ranging from solar-driven vapor generation to self-healing materials. − While composites of PDA and polymers have been demonstrated to present significant photothermal properties, they are all in multicomponent, heterogeneous forms, which are difficult to fabricate and restrict eco-friendliness, cost-effectiveness, and the ease of applicability of the resulting materials.…”

A polydopamine-polyurethane (PDA-WPU)-based polymeric matrix with efficient light-to-heat conversion properties that can initiate light-activated temperature elevations is presented. The polymerization of dopamine monomer in a pre-synthesized aqueous polyurethane dispersion resulted in hybrid polyurethane-polydopamine particles via the coating of discrete waterborne polyurethane (WPU) particles with photothermal polydopamine. The resulting polydopamine-polyurethane (PDA-WPU) dispersions presented a unimodal particle-size distribution and particle sizes that increased as a function of the initial dopamine concentration and polymerization time. Films cast from PDA-WPU dispersions were black-colored and presented a homogeneous morphology with contact angles that decreased with increasing PDA content. While the thermal decomposition behavior and thermal conductivity values of hybrid PDA-WPU films were improved relative to neat WPU films, the glass transition temperatures remained unaffected and the films presented acceptable mechanical properties. PDA-WPU films prepared with the highest amount of polydopamine reached 105.8 °C when irradiated with solar light at 3 sun for 20 min. Five min of irradiation with NIR laser light at 800 mW/cm2 elevated the temperatures of the PDA-WPU films from room temperature to 138.6 °C. Moreover, PDA-WPU dispersions were molded in the form of a container to investigate their potential in solar-driven water-evaporation applications. The hybrid PDA-WPU polymer matrix prepared via a facile postsynthesis modification of WPU dispersions with polydopamine synergistically possesses the features of both components and presents strong photothermal activity along with its easy-to-apply, nanoparticle-free, and environmentally friendly nature; thus, this matrix can be viewed as a promising candidate for a wide range of photo-driven applications.

“…They declared that due to the synergistic biophysical and biochemical modes of biocidal action of antibacterial superhydrophobic coatings, it was feasible in various applications. Duan et al [ 94 ] prepared superhydrophobic and antibacterial wood by self‐polymerization of dopamine, chemical deposition of Cu NPs, and hydrophobic modification using fluorosilane. The antibacterial activities of wood samples were assessed based on the size of inhibition ring ( Figure ).…”

Microorganisms have existed for hundreds of millions of years and they have adapted to colonize on surfaces. [1] Bacteria are ubiquitous in the human living environment. Most bacteria spread through medical equipments and contacting with each other. [2] All over the world, the diseases caused by bacterial infections have brought terrible catastrophe to human beings. [3][4][5][6][7] Generally, people infected with infectious diseases are directly or indirectly related to contact with pathogenic microorganisms. The main stages of the attachment of bacteria at the interface include the migration of bacteria to the surface, the reversible and irreversible interactions between bacteria and the interface, the specific adsorption of bacteria on the substrate, and the proliferation of bacteria, thus forming a bacterial biofilm on the surface (Figure 1). [8] The bacteria can multiply quickly under suitable conditions, which induce various diseases and cause invalidation of apparatus. The colonization of bacteria on surfaces can result in chronic infections, [9] the failure of medical implants, [10] the biological corrosion of industrial equipments, [11] reducing various surface properties, such as petroleum and other pipelines systems, clothes, and other harmful phenomena. [12] Currently, antibiotics are mainly used to inhibit or kill bacteria to maintain surface hygiene and prevent infections. However, as bacteria develop resistance to antibiotics, it is suggested that antibiotics should be much more cautiously used. It is estimated that antimicrobial resistance infections will kill as many as 10 million people every year by 2050. [13] Antimicrobial resistance is now an urgent international issue that requires imperative solutions, more effective antibacterial techniques are needed to fight bacterial infections. Inspired by the superwetting properties of plants and marine life, Li et al. [14] reviewed the research progresses of the preparation of superwetting materials including of superhydrophobic/superoleophilic and superhydrophilic/underwater superoleophobic materials and their applications for removal of organic pollutants, which provided a basis for the design of a new type of superwetting materials that efficiently remove organic pollutants in the water. Similarly, Tian et al. [15] developed a superwetting thin-film nanofibrous composite membrane with antifouling, self-cleaning, and oil-in-water emulsions separation properties. The as-prepared carbon nanotubes (CNTs) layer with superhydrophilic and underwater superoleophobic properties could absorb water as a selective layer to remove oil droplets from oil-in-water emulsions to present antifouling. The self-cleaning properties were promised by the continuously up-flowed permeate water. They claimed that the work provided a new insight for developing oil/water separation membranes which suffer from fouling and clogging. Also, Li et al. [16] summarized the recent progresses in smart polymeric materials for fabricating switchable superwettability surfaces and their oi...

“…Se ha investigado que la dopamina puede formar una capa superadhesiva de polidopamina (PDA) en la superficie de casi todo tipo de materiales orgánicos o inorgánicos mediante polimerización por auto-oxidación [06] . Por lo tanto, la polidopamina puede usarse como un medio con muy buena adherencia entre el sustrato (que en este caso podría ser un panel de material orgánico) y las nanopartículas de cobre.…”
