摘要 ：
Layer by layer (LBL) self-assembly coatings upon expandable polystyrene (EPS) surface play an important role in improving its flame retardancy. However, a large number of layers is needed to achieve a satisfied fire performance, and the coatings are difficult to adhere on the inert EPS surface, resulting in the poor durability. In this work, the surface of EPS was activated by ultraviolet ozone (UVO) with the appearance of oxygen contained groups, then a LBL coating with only two bilayers (branched polyethyleneimine (BPEI)-kaolinite (kaol)-BPEI-diethylene triamine penta (methylene phosphonic acid)) was covalently connected on the EPS surface. Compared with neat EPS, the obtained E-K5D30 sample increased the value of limiting oxygen index (LOI) from 18.8 % to 37.7 %, improved the ignition time from 59 s to 95 s, reduced the peak heat release rate (pHRR) value from 282.0 kW/m(2) to 220.9 kW/m(2), and enhanced the char residues from 6.3 % to 32.3 % after the combustion. Moreover, an ultraviolet (UV) curing layer with P/N elements was prepared upon E-K5D30 sample to maximize the flame retardant durability. A novel amino-intercalated kaol was used to play a smoke suppression role. The results showed that E-K*D-5(30)-P8N3 sample further increased the LOI to 39.2 %. Even after 12 h washing, the E-K*D-5(30)-P8N3 sample exhibited a slight LOI reduction to 37.8 %, and fire performance index (FPI) value of 0.405 m(2)s/kW, showing the successful construction of coatings with good fire safety and flame retardant durability.

摘要 ：
In this work, a metal organic framework (Fe-MOF) with the effect of absorbing toxic gases and good compatibility was synthesized by chelating a novel organic ligand contained carbonization groups (reacted by tris(hydroxymethyl) aminomethane and 1,4-piperazine dialdehyde) with iron salt. Then, it was used as the synergist to improve the efficiency of intumescent flame retardant (IFR) within polystyrene (PS) substrate. With the addition of 20% IFR and 2% Fe-MOF, the obtained PS composites exhibited a limiting oxygen index (LOI) value of 28.3% and a UL rating of V-0. Moreover, the peak heat release rate (pHRR), total heat release (THR), and total smoke production (TSP) of PS composites were decreased by 77.6%, 35.2%, and 33.7%, respectively. According to the mechanism analysis, it was found that Fe-MOF mainly acted in the condensed phase, contributing to the existence of dense char residues with the presence of IFR system. In addition, the good compatibility of organic ligand in Fe-MOF with PS substrate could partially alleviate the deterioration of mechanical properties due to the addition of IFR. For PS-20%IFR/2%Fe-MOF, the impact strength was improved from 1.7 kJ/m(2) (PS-22%IFR) to 2.2 kJ/m(2), the tensile strength was also increased from 21.3 MPa (PS-22%IFR) to 22.4 MPa.

摘要 ：
Isophorone diisocyanate (IPDI) was encapsulated successfully within double-layered shells, and final microcapsules showed outstanding self-healing functions in cement paste. The well-dispersed microcapsules had a diameter of 347.0 +/- 103.4 mu m, shell thickness of 3.1 +/- 0.4 mu m, and core fraction around 74.8% +/- 1.9% by weight. The diameters of microcapsules were adjustable by varying agitation rates. The beginning weight-loss temperature of microcapsules was 200 degrees C, implying good thermal stability. The final microcapsules affected slightly the workability and setting time of fresh self-healing cement paste. Although the mechanical strength of hardened self-healing cement paste was decreased with the increase of microcapsule concentrations, the open porosity was improved obviously from 33.5% (control samples) to 31.8% when 5.0% by weight of microcapsules was introduced. The interfaces of microcapsules were compatible enough with cement paste without obvious delamination. Especially, the self-healing cement paste showed outstanding self-healing functions in open air when 10.0% by weight of microcapsules was introduced. (C) 2021 American Society of Civil Engineers.

摘要 ：
In this work, a novel intumescent flame retardant (IFR) system was fabricated by the introduction of chitin as a green charring agent, ammonium polyphosphate (APP) as the acid source, and melamine (MEL) as the gas source. The obtained chitin-based IFR was then incorporated into a polylactic acid (PLA) matrix using melt compounding. The fire resistance of PLA/chitin composites was investigated via the limiting oxygen index (LOI), UL-94 vertical burning, and cone calorimeter (CONE) tests. The results demonstrated that the combination of 10%APP, 5%chitin and 5%MEL could result in a 26.0% LOI, a V-0 rating after UL and a 51.2% reduction in the peak heat release rate during the CONE test. Based on the mechanism analysis from both the morphology and the chemical structure of the char, it was suggested that chitin was a promising candidate as a charring agent for chitin reacted with APP and MEL with the formation of an intumescent layer on the surface.
