“…In this paper, we present a novel mussel‐inspired synthetic adhesive based on dopamine and hydrophobic n ‐alkylamine (lauryl, octyl, hexyl and butyl)‐modified polyaspartamide derivatives. Compared to the PolyAspAm(DOPA/EA) polymer system previously studied by our group, by introducing a hydrophobic alkyl moiety located close to the catechol groups, the corresponding adhesive polymer glue showed much greater adhesive strength towards various types of substrates such as glass and metals as well as several common plastics. Additionally, the glue showed an enhanced resistance to water molecules in aqueous environments.…”

The development of wet bioadhesives for tissue fixation and wound care remains a challenge. While various commercial bioadhesive products based on both natural and synthetic materials are available, both types of adhesive have several drawbacks including weak adhesion or toxicity. In this study, we present a novel mussel‐inspired synthetic adhesive based on polyaspartamide derivatives modified with dopamine and a series of hydrophobic n‐alkylamines (lauryl, octyl, hexyl and butyl), which shows very strong adhesion toward various types of substrates such as paper, glass and metals as well as several common plastics (0.1–0.6 MPa). Additionally, the effect of adding metal ions (Mg2+, Ca2+) as a coordination crosslinker to enhance adhesion performance was investigated using acryl plastic substrate. Even under deionized water conditions, the strong adhesion was found to be maintained for an appreciably long time after 24 h. This novel and biocompatible polymer glue system has potential in various applications including as a medical tissue adhesive and sealant. © 2018 Society of Chemical Industry

A facile fabrication of strongly adhesive hydrogel based on high‐molecular‐weight poly(2‐ethyl‐2‐oxazoline) (PEOX) and tannic acid (TA) has been demonstrated. PEOX and TA form instantaneous complex gel via strong hydrogen bonding interaction by simple mixing in an aqueous system. The characteristics of the PEOX–TA complex gels was investigated by using Fourier transform infrared spectroscopy, thermogravimetric analysis, differential scanning calorimetry, and scanning electron microscopy to reveal their network structure, composition, and thermal properties. The prepared wet complex gel system demonstrated excellent adhesive performance on different substrates with comparable results to pure PEOX polymer. It was considered that many factors affect the adhesive performance of the PEOX–TA gel such as the TA content, the molecular weight of PEOX, and water content. This adhesive gel system has potential for use in various fields including biomedical application as a novel and low‐cost adhesive or sealant. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.

With the decreasing of petrochemical resources and the increasing severity environmental pollution, the development of environmentally friendly adhesive technology using renewable resources has attracted more and more attention. Inspired by mussels, a novel biomimetic adhesive synthesized using polyaspartamide derivative (PolyAspAm(DOPA/OA)) and alkali lignin (AL). The physical/chemical structure and properties were examined by 1H‐NMR, Fourier‐transform infrared spectroscopy, thermo gravimetric analysis, scanning electron microscopy, water absorption, in vitro cytotoxicity, lap shear tensile, and three‐point bending tests. The adhesive capacity was improved significantly when AL added into PolyAspAm(DOPA/OA). The lap shear tensile for four different substrates (metal and plastic) both increased greatly. The underwater adhesion test possessed good underwater adhesion properties. The results confirmed that hydrogen bonds and chain entanglement were formed between PolyAspAm(DOPA/OA) and AL. It was the introduction of catechol groups and physical–chemical interactions between PolyAspAm(DOPA/OA) and AL improved the adhesion strength and water resistance of the adhesive. Moreover, the corn stover non‐wood boards were prepared by one‐step hot pressing using PolyAspAm(DOPA/OA) with AL adhesives. The three‐point bending of corn stover non‐wood boards increased from 5.00 ± 0.03 to 14.85 ± 20.1 MPa. Overall, this work shows that a nontoxic, environmentally friendly PolyAspAm(DOPA/OA) with AL adhesive has extensive application prospects.
