“…It is known that the catechol containing dopamine molecules can be easily transformed into their reactive quinone counterparts in the presence of an alkaline solution or a strong oxidizing agent, and then induced to polymerize [30][31][32]. This oxidation-induced polymerization leads to the production of the cross-linked polymers baring catechol and quinone functionalities, which can be exploited for further modifications [33,34]. In the present work, PAA/ PEO fibers were immersed into the dopamine acidic solution containing NaIO 4 as the oxidant, whereby dopamine was oxidized to the corresponding quinone.…”

Elastic, repairable and conductive fibers are desirable in the newly emerging field of soft electronic and wearable devices. Here, we design a multifunctional fiber by incorporation of different components to optimize its performance. The combination of the poly(acrylic acid) (PAA) and poly(ethylene oxide) (PEO) through hydrogen bonding endows the fiber with high elasticity and repairability. Polydopamine (PDA) significantly increases the stability of the fiber, thus the fiber will not dissolve in alkaline solutions and still keep the repairable ability. The fiber shows a reversible swelling-shrinking property as pH values go up and down. Further, the conductive component, carbon nanotube, is adsorbed at the swelling state and then is fastened with fiber shrinking.

“…The size of hollow polymer capsules that prepared by LbL‐assembly technique is mainly determined by the size of the templates, which should remain stable during the layering process and can be easily dissolved without any effect on the structure of assembled capsules afterward . So far, the most frequently used colloid templates are silica particles, CaCO 3 , MnCO 3 and polystyrene (PS).…”

“…It is worth to remember that PDA capsules possessed many amino groups, rendering them positive net charge; hence, it facilitated the release of insulin molecules into the medium . The utilization of dopamine‐modified poly(acrylic acid) and poly(vinylpyrrolidone) to fabricate pH‐responsive capsules was also mentioned by Sun and colleagues . However, the capsule release mechanism was tested on dye molecules only, no further release of drug molecule was included.…”

Polymeric hollow capsules have attracted increasing interest for the development of controlled drug delivery systems due to their capacities to load high amount of drugs and be able to finely tune the drug release profile. Various methods and strategies for capsule preparation and drug loading have been developed over time. Besides that, the controlled drug release from hollow capsules upon external and internal triggers is of great interest and has been a research focus in this area. This article aims to give the most recent progress review on hollow capsule based controlled drug delivery systems with a highlight on strategies being used for drug loading and stimuli-release. In detail, the fabrication of hollow capsules using templateassisted or template-free methods will be introduced first. This will be followed by current strategies for pre-loading and postloading of therapeutic agents into capsules. The article will then be particularly focused on discussing diverse drug-release systems corresponding to various stimuli conditions including temperature, pH, ultrasound, light irradiation and enzyme degradation.

“…Thermoresponsive Polymere, wie Poly( N ‐isopropylacrylamid) (PNIPAM), können mit TA kombiniert werden, um sowohl temperatur‐ als auch pH‐responsive Dünnschichten zu entwickeln . Eine neuere Entwicklung ist die Modifikation synthetischer Polymere wie Polyacrylsäure mit Catecholgruppen, um ein mehrschichtiges Wachstum mit PVPON zu ermöglichen …”

Phenolische Bausteine für die Assemblierung von Funktionsmaterialien

Phenolische Materialien sind seit langem für ihre Verwendung in Farbtinten, in Holzbeschichtungen und zur Ledergerbung bekannt. In letzter Zeit ist jedoch ein wachsendes Interesse an der Entwicklung moderner Werkstoffe aus phenolischen Bausteinen zu verzeichnen. Die intrinsischen Eigenschaften von phenolischen Verbindungen, wie Metallchelat‐Bildung, Wasserstoffbrücken, pH‐Ansprechverhalten, Redoxpotentiale, Radikalfänger, Polymerisation und Lichtabsorption, haben sie zu einer eigenständigen Klasse von Strukturelementen für die Synthese von funktionellen Materialien gemacht. Aus Phenolverbindungen hergestellte Materialien behalten viele ihrer nützlichen Eigenschaften, oft mit synergistischen Effekten bei Anwendungen, die von der Katalyse bis zur Biomedizin reichen. Dieser Aufsatz gibt einen Überblick über die verschiedenen funktionellen Materialien, die aus natürlichen und synthetischen phenolischen Bausteinen hergestellt werden können, und über ihre Anwendungen.
