Protein-tannin interactions towards fabricating flame-retardant, UV-resistance, antibacterial and mechanical-reinforced PA66 fabric
The “Protein-polyphenol interactions” is a hot research topic in the field of interaction between biological macromolecules. Strong interactions between biomass polyphenolic tannins and proteins can be generated through covalent and non-covalent bonds. Inspired by this, keratin (Ker) and oxidized tannin (TA) was co-deposited on polyamide 66 (PA66) fabric to fabricate OTA/Ker coated PA66 fabric (PA66@OTA/Ker), which was then chelated with Fe3+ to prepare fire resistance and anti-dripping PA66 fabric (PA66@OTA/Ker@Fe). The results showed that the total heat release rate (THR), peak heat release rate (pHRR) and total smoke production (TSP) of PA66@OTA/Ker@Fe were reduced by 51 %, 57 % and 52 %, respectively. PA66@OTA/Ker@Fe had a residue char of 21.6 % at 800 °C under N2 atmosphere. In addition, the LOI of PA66@OTA/Ker@Fe increased from 20.5 % of the control sample to 28.5 % and reached a UL-94 V-0 rating. Besides, PA66@OTA/Ker@Fe exhibited excellent UV resistance, good mechanical and anti-bacterial properties. This work provides an eco-friendly strategy for developing multifunctional PA66 fabrics.
期刊介绍：
The aim of this international journal is to analyse and publicise the progress and current state of knowledge in the field of organic coatings and related materials. The Editors and the Editorial Board members will solicit both review and research papers from academic and industrial scientists who are actively engaged in research and development or, in the case of review papers, have extensive experience in the subject to be reviewed. Unsolicited manuscripts will be accepted if they meet the journal''s requirements. The journal publishes papers dealing with such subjects as:
• Chemical, physical and technological properties of organic coatings and related materials
• Problems and methods of preparation, manufacture and application of these materials
• Performance, testing and analysis.
