Sericin is a byproduct generated during silk processing, which generates significant environmental concerns due to its environmental pollution problem. However, such a protein structure contains an abundance of active functional groups and has the potential to be used as a biomass flame retardant. In this work, we first synthesized a sericin-based intumescent flame retardant (IFR), which was subsequently applied onto cotton fabric through chemical grafting. The resulting IFR-treated fabrics demonstrate high flame retardant efficiency with exceptional durability. Especially, the cotton fabric treated by a 10% concentration of an IFR solution possesses a remarkable increasing limiting oxygen index value of 30.57% and a quick selfextinguishing property. Moreover, the microscale cone calorimeter test shows that the peak heat release rate and total heat release values are greatly reduced by 82.79% and 73.77% compared with the pure cotton fabric. Remarkably, the IFR-treated fabrics exhibit excellent washing resistance, as evidenced by their ability to maintain a self-extinguishing ability in the vertical burning test even after undergoing multiple wash cycles. Also, the samples have no formaldehyde residue and meet the requirements of green environmental protection. This work not only expands the application range of sericin but also presents a novel method for preparing efficient and durable IFR for cotton fabrics, which effectively balances functional requirements and offers promising prospects for practical use.

“…Figure 9 shows the residual's optical images and SEM images of paraffin/EP and W‐UiO66‐PPA‐paraffin/EP, the paraffin/EP shows a fluffy char layer, while the W‐UiO66‐PPA‐paraffin/EP displays a compact and integrity residual char. Furthermore, the higher the graphitization degree of char layer, the better the flame retardancy effect of condensed phase 28 . The graphitization degree of char layer is explored by Raman spectra and the results are showed in the right part of Figure 9.…”

“…The paraffin/EP and W‐UiO66‐PPA‐paraffin/EP both show two representative peaks, D (around 1592 cm −1 ) band and G band (around 1350 cm −1 ). The area ratio of D and G bands (I D /I G ) represents the graphitization degree, the higher the I D /I G , the lower the graphitization degree 28 . According to the calculation results, the I D /I G value of paraffin/EP is 3.87, and the W‐UiO66‐PPA‐paraffin/EP has a lower I D /I G value of 3.15, which reveals that the graphitization degree of residual char for paraffin/EP becomes higher after adding W‐UiO66‐PPA.…”

Paraffin is a potential thermal energy storage material, but leakage and flammability are the two major problems affecting its storage and safe use. Here, a novel flame retarded paraffin/epoxy resin composite was developed by using paraffin, epoxy resin and hollow metal organic framework (W‐UiO66‐PPA) as thermal energy storage material, supporting material and flame retardant, respectively. The thermal energy storage and flame retardancy performances were examined with differential scanning calorimetry, vertical burning, limiting oxygen index and cone calorimeter tests. The results show that the paraffin/epoxy resin retains intact without leakage when the content of paraffin reaches 40 wt%, and this material exhibits high melting latent heat and remarkable thermal recycling property. In addition, the flame retarded paraffin/epoxy resin shows excellent flame retardancy, which is attributed to the following three aspects: (1) the hollow structure with open vertices of W‐UiO66 is capable of absorbing and collecting the combustible gasses produced by the combustion of epoxy resin; (2) the Zr and W elements of W‐UiO66 can facilitate catalytic charring and form a dense char layer; (3) phosphorous‐containing free radicals are able to capture OH· and O· free radicals during the combustion of paraffin and epoxy resin, thus interrupting the combustion chain reaction. On the whole, the flame retarded paraffin/EP possesses excellent thermal energy storage, thermal recycling, and flame retardancy properties. Our work provides a fantastic inspiration for the rational design of other flame retarded form‐stable phase change materials.

Enhancing the flame retardancy with minimal impact on the mechanical and thermal performances of polymers remains a challenge. This study synthesized a phosphorus/nitrogen‐containing silane compound (D) using polyformaldehyde, KH‐550, and 9,10‐dihydro‐9‐oxa‐10‐phosphaphenanthrene‐10‐oxide (DOPO) as raw materials through the Kabachnik‐Fields reaction. After that, D was grafted onto the surface of graphene after hydrothermal treatment to obtain a nano hybrid flame retardant (D‐GR). And D‐GR/EP composites exhibited good flame resistance (LOI = 30.1% and UL‐94 reaches the V‐1 rating) even if the load on D‐GR was 1 wt%. Indeed, the total heat release, the peak heat release rate (PHRR), and the total smoke release of 1% D‐GR/EP dropped by 13.54%, 28.62%, and 44.32%, respectively, in comparison to pure EP. The mechanical performance of 1% D‐GR/EP was effectively maintained, as indicated by the results of impact, tensile and flexural tests. A systematic evaluation indicated that the accession of D‐GR effectively inhibited smoke and heat releases that are ascribed to the synergistic effect of phosphorus/nitrogen‐containing silane compound and graphene. In this study, a facile method was provided for the synthesis of halogen‐free flame‐retardant epoxy composites with superior performances. The combustion products of the as‐prepared composites complied with green and environmental protection standards.
