Texture-Dependent Adhesion in Polydopamine Nanomembranes
ACS Applied Materials & Interfaces, 2018The conformal nature of in situ polymerization of adhesive dopamine molecules permits the strong underwater adhesion between polydopamine (PDA) nanomembranes and the target substrates. However, the adhesive interaction between the postdeposit PDA nanomembranes and other macrobodies is strongly influenced by the texture of PDA nanomembranes.

Material-Selective Polydopamine Coating in Dimethyl Sulfoxide
ACS Applied Materials & Interfaces, 2020Polydopamine coating is known to be performed in a material-independent manner and has become a popular tool when designing a surface-functionalization strategy of a given material. Studies to improve polydopamine coatings have been reported, aiming to reduce the coating time (by transition metals, oxidants, applied voltages, or microwave irradiation),

Compression Isotherms of Polydopamine Films
Colloid Journal, 2020Polydopamine is formed via dopamine hydrochloride (DAH) polymerization in a slightly alkaline medium (pH 8.5) both in a solution bulk and at a liquid–gas interface. Atmospheric oxygen and oxygen dissolved in the bulk solution serves as an oxidizing agent.

Applications of Polydopamine in Implant Surface Modification
Macromolecular Bioscience, 2023AbstractThere is great clinical demand for orthopedic and dental implant surface modification methods to prevent osseointegration failure and improve implant biological functions. Notably, dopamine (DA) can be polymerized to form polydopamine (PDA), which is similar to the adhesive proteins secreted by mussels, to form a stable bond between the bone ...

Polydopamine-based photonic crystal structures
Journal of Materials Chemistry C, 2013Active photonic crystals (PC) or photonic crystal heterostructures have many applications such as chemical and biological sensors, active colour displays, structural colour printing and fluorescence enhancement. However, photonic crystal structures with the different functions mentioned above require different preparation methods, and some of them ...

Surface wrinkling on polydopamine film
Applied Surface Science, 2016Abstract In this paper, we report a non-lithographic strategy to realize surface patterns on polydopamine films. It is based on surface wrinkling, which is induced on polydopamine (PDA) films that are grown on uniaxially pre-strained polydimethylsiloxane (PDMS) substrates through self-polymerization of dopamine, followed by the pre-strain release. We

Skin Pigmentation‐Inspired Polydopamine Sunscreens
Advanced Functional Materials, 2018AbstractCommercial sunscreens usually rely on multiple component formulas against solar irradiation, including UV filters, antioxidants, and nanomaterial matrices. While many efforts are devoted, concern has arisen that the effectiveness and safety issues of most sunscreens are largely limited by their complex formulations, photostability, and toxicity.

Polydopamine deposition at fluid interfaces
Polymer International, 2016AbstractWhen catecholamine solutions are put in the presence of an oxidant, a spontaneous oxidation process allows one to coat the surface of all known classes of materials with a brown‐black insoluble material. This material is related to eumelanins from both compositional and structural points of view. Simultaneously with the film deposition at solid/
