“…Such improved T d are even more pronounced than some inorganic nanomaterials reinforced CNF aerogels (Guo et al 2019;Wang et al 2019). The superior thermal stability of PCAs are attributed to (1) the CNF was coated by polydopamine by in-situ polymerizaand the polydopamine acted as physical barrier to retard the decomposition of CNF, and (2) the free radical scavenging ability of polydopamine could eliminate the radicals generated by the breaking of C-C bonds, and block chain-scission depolymerization (Fang et al 2020;Cho et al 2015;Yang et al 2020). The improved thermal stability of PCAs is beneficial to their thermal applications.…”

“…For example, PCA1 has LOI value of 24.5%, and as the polydopamine content was reached 30 wt%, the PCA3 become nonflammable with LOI value of 28.7%, and the LOI value further increases to 29.2 and 33.1 in PCA4 and PCA5. The scavenging of free radical by polydopamine, thus suppressing fuel supply during combustion is also thought to be the main reason for this enhanced flame resistance of PCAs (Fang et al 2020;Cho et al 2015;Yang et al 2020). Additionally, the catalysis effect of Fe 3?…”

“…The excellent adhesive properties, good biocompatibility and antioxidant properties of polydopamine have encouraged researchers to exploit polydopamine in various biological and surface coating applications (Ryu et al 2018;Lee et al 2020;Zhang et al 2021a, b). Recently, polydopamine has been incorporated into polymer composites to enhance the mechanical, thermal, antioxidant, and UV-shielding properties (Xiong et al 2014(Xiong et al , 2016Wang et al 2017;Fang et al 2020). In addition, the use of polydopamine as coating or filler to improve the flame retarding property of polymer foam or composites has also been demonstrated due to its good radical scavenging ability (Fang et al 2020;Cho et al 2015;Yang et al 2020).…”

Cellulose nanofibril (CNF) aerogels have attracted great interests in recent years due to the low cost, sustainability and biocompatibility of raw CNF. However, the poor thermal stability and flammable feature of CNF aerogels have limited their wider applications. In this paper, polydopamine/CNF composite aerogels with good comprehensive properties are fabricated by modification of CNF with polydopamine and metal coordination bonds crosslinking. The microstructure and properties of composite aerogels are thoroughly characterized by a variety of tests. It is found that the microstructure of aerogels are more regular and the compressive strength of aerogels are enhanced by the incorporation of polydopamine and Fe 3? crosslinking. Importantly, the thermal stability and flame resistance of aerogels are significantly improved, which permit the application of composite aerogels in high-temperature thermal insulation. In addition, the reversible characteristic of metal coordination bonds allows the water induced healing of fractured composite aerogels. This study is expected to provide information for future development of green and high-performance aerogels.

This paper reported a facile and green method for surface functionalization of cellulose nanofiber (CNF) by oxidative polymerization of tannic acid (TA) and ethanediamine. The modified CNF (T‐CNF) was then used as filler for constructing polyvinylalcohol (PVA) composites. Experimental results suggested that the surface polar groups on CNF were increased after modification. The abundant surface polar groups allowed the homogeneous dispersion of T‐CNF in PVA matrix, and the formation of hydrogen bonds between fillers and matrix. This interfacial interaction and the high aspect ratio of T‐CNF have restricted the thermal mobility of polymer chains and increased the glass transition temperature and melting temperature of PVA. Tensile test suggested the good mechanical properties of composites, and the reinforcement effect of T‐CNF on PVA was better than that of un‐modified CNF. The good free radical scavenging ability of polymerized TA also improved the thermal stability of composites and endowed the composites with good antioxidant property. The T‐CNF/PVA composites with improved properties hold great promising applications in fields such as packaging, adhesive and coating. This work is expected to provide alternative and green approach for the surface modification of CNF and the preparation of multifunctional CNF composites with good properties.

This paper utilizes the reaction of phytic acid (PA) and urea (UM) in polyvinyl alcohol (PVA) solution to synthesize flame retardant gasses (CO2, NH3) for the preparation of PVA composite films containing flame retardant microbubbles. The flame retardancy of PVA composite films was assessed using methods including limiting oxygen index (LOI), vertical burning (UL 94), and cone calorimetry. The results indicated an increase in the LOI of the PVA composite film containing flame retardant microfoam from 20% to 30% compared with the pure PVA film, and that UL 94 reached VTM‐0. Furthermore, its peak exothermic rate and total exothermic amount were reduced by 36.25% and 38.92%, respectively, compared with the pure PVA film. The investigation of the flame‐retardant mechanism employed thermogravimetric‐infrared (TG‐IR), scanning electron microscopy (SEM), Raman spectroscopy, and infrared spectroscopy. The results demonstrate that the CO2 and NH3 flame retardant microbubbles within the composite film render it less ignitable at the initial stage, and that the internal UM of the composite film continues to decompose, releasing CO2 and NH3 upon heating. In addition, the acidic substances decomposed by PA during combustion promote the dehydration, cross‐linking, and cyclization of PVA, generating chemical structures such as POC, POP, and PO4 with enhanced thermal stability. This encourages the formation of a continuous, dense charcoal layer and impedes the transfer of oxygen and heat into the interior.
