“…It is found that residues of IFR only exhibit bumps, indicating the formation of glassy structures corresponding to phosphate glasses. In contrast, there are some obvious diffraction peaks in the spectrum of IFR‐ONSep, which belong to SiP 2 O 7 and NH 4 Mg(PO 3 ) 3 , and this confirms reactions between ONSep and APP have occurred, leading to synergistic effects on flame retardancy.…”

Summary In this work, an efficient approach to improving the fire retardancy and smoke suppression for intumescent flame‐retardant polypropylene (PP) composites is developed via incorporating functionalized sepiolite (organo‐modified sepiolite [ONSep]). The PP composites with different amounts of intumescent flame retardants and ONSep were prepared by melt compounding. The morphology, thermal behavior, fire retardancy, smoke suppression, and mechanical property of flame‐retardant PP composites were studied. The results indicate an appropriate amount of ONSep in the flame‐retardant PP composites can increase thermal degradation temperature and char formation as well as a reduction of the peak heat release rate and total heat release; moreover, the addition of ONSep significantly decreases the CO production, total smoke production, smoke production rate, and smoke temperature. Simultaneously, the impact strength of intumescent flame‐retardant PP composite is also maintained by introducing an appropriate amount of ONSep as compared with that without ONSep.

Environmental problems caused by polymers and polymers have historically dominated both academic and industrial attention. Sustainable biodegradable wood-plastic composites (WPCs) as an optimum can solve the environmentally critical problems caused by petroleum-based polymers. However, they are flammable, prone to fire accidents, and often have a contradiction between mechanical performance and flame-retardant properties, which limits their range of applications. Here, we reported a flame-retarded poly(butylene succinate) (PBS) WPC prepared with modified natural fiber-magnesium hydroxide sulfate whisker (MHSH) hybrids and intumescent flame retardants (IFRs). The mechanical performance, flame-retardant properties, thermal stability, and actual fire simulation parameters of composites were investigated. Owing to the unique composition characteristics of modified cassava dregs-MHSH hybrids, the mechanical properties (70P/23I/5C/2M, flexural strength was 39.2 AE 1.960/MPa, impact strength was 7.95 AE 0.3975/ [KJ/m 2 ]), flame retardant properties (70P/23I/5C/2M, the limiting oxygen index value was 39.6%, UL-94 was V0) and thermal stability of WPC have been improved. Thereby, the balance between mechanical performance and flame retardant properties of biocomposites has been achieved in the practical engineering requirements. Furthermore, cone calorimeter data indicated that modified cassava dregs-MHSH hybrids played a role in improving the fire safety of composites. The total heat release, total smoke produce, toxic gas release, and total oxygen consumed of 70P/23I/5C/2M were lowered compared with those of 70P/25I/5C. Dynamics analysis indicated that the addition of modified cassava dregs-MHSH hybrids increased the activation energy of composites. Based on the experimental and analyses data, especially the morphological characterization of char residue analysis, it illustrated that modified cassava dregs-MHSH hybrids have a reinforcement and flame-retardant effect. The combusted residue of the incorporated modified cassava dregs-MHSH hybrids could support the three-dimensional charred layer formed by the combustion products of the IFR and the PBS. Thus, the more stable threedimensional charred layer could not only effectively reduce thermal conductivity of composites but also hinder the propagation of heat into the interior substrate, thereby improving the flame-retardant properties of the WPC.

World cultural heritage is an invaluable resource and must be preserved. Conventional packaging materials, such as polystyrene‐PS, polyurethane (PU) foams, paper‐like tissue, and nylon fabric, are petrol‐based. According to Agenda 2030, and Green Deal directives, the development of alternative bio‐based materials has gained significant scientific and technological relevance. In this scenario, a new sustainable packaging material for safe storage and transporting of the artifacts, based on a sustainable PU foam filled with 6 wt.% of Zeolite 4A, is herein proposed. Zeolite 4A dispersion into PU matrix imparts higher compression strength and energy absorption capability with respect to unloaded materials (7‐fold increase), owing to its remarkable cell nucleating effect. The proposed foam can adsorb water vapor, up to 29 wt.%, thus contributing to regulating the humidity around the artifact. A remarkable advantage of the developed foam is the possibility to use it as plaster for precisely casting the article to protect, resulting in strongly improved handling, protection, and transportation safety with respect to conventional packaging solutions. A proof‐of‐concept workflow is proposed, consisting of: i) 3D scanning of the original artifact, ii) its replication through 3D printing, iii) the use of such replica to prepare a tailored cast of the artifact shape.This article is protected by copyright.
