We successfully synthesized a series of novel symmetrical solution processable small molecules (APPM, AAPM and ATPM) consisting the electron-accepting moiety (2-pyran-4-ylidenemalononitrile) (PM) electron-donating (triphenylamine) linked by different moieties (phenothiazine, triphenylamine thiophene) through Suzuki coupling reaction. Differential scanning calorimetry (DSC) measurement indicates that APPM shows relatively high glass-transition temperature ca. 137 °C 163 °C, while melting...
Abstract Purpose The purpose of this paper is to provide the details developments research works in distribution characteristics air gaps within firefighters' clothing and methods evaluate effect on thermal protective performance clothing. Design/methodology/approach In paper, was first analyzed, were summarized as thickness, location, heterogeneity, orientation dynamics. Then, evaluation gap fighters' reviewed for both experimental numerical studies. Findings layers between skin play an...
A series of solution processable small molecules (4TPM, 6TPM, and 8TPM) were synthesized with 2-pyran-4-ylidenemalononitrile (PM) as the electron-accepting unit oligothiophene different numbers electron-donating unit. Differential scanning calorimetry (DSC) measurement indicated that melting point crystal temperature increased increase thiophene number. UV−vis absorption demonstrated combination PM resulted in an enhanced intramolecular charge transfer (ICT) transition, which led to...
For accurate prediction of thermal protective performance firefighter clothing, a realistic assumption about the heterogeneous distribution air gaps underneath clothing is necessary.In this study, numerical model heat transfer through under flash fire exposure was developed.First, models and fluid motion were validated with data from scientific literature.The verified further developed then used in subsequent parametric study to quantify effects gap distributions.The results revealed that...
Purpose The purpose of this paper is to determine the effect flash fire exposure on mechanical properties single-layer thermal protective clothing. Design/methodology/approach full-scale flame manikin tests were performed simulate exposure. Two typical fire-resistant fabrics investigated. was divided into seven body parts and specimens meeting requirements tensile tear strength standards sampled. Fabric thickness, mass per unit area, measured analyzed. Findings results revealed significant...
This paper presents the effects of BCl3 additive gas on physical damage and prevention against in oxide hard-mask-based Al etching. The addition TiN/Ti break-through step effectively passivated sidewall upper notching damage; however, profile was easily distorted under excessive added. bottom depth decreased with decreasing BCl3/Cl2 ratio over-etch step. As is less than or equal to 0.625, eliminated. Nevertheless, low would result increasing residues because insufficient passivation at flow...
Ambient temperature steps between typical non-work and hot work environments will lead to clothing heat storage release, which is crucial for human health thermal comfort. In this study, the influence of five types ambient (from 0ºC/5ºC/10ºC/15ºC/20ºC 40ºC 0ºC/5ºC/10ºC/15ºC/20ºC) on release in was investigated using a manikin. A moving temperature-controlled refrigerated incubator constructed realize step conditions. Results showed that magnitude positively related release. Some 80% amount...
Abstract In firefighting situations, firefighters will encounter multiple flame exposures during go through the fireground several times. this study, effects of on thermal shrinkage and protective performance three fabrics used in clothing were investigated. The fabric surface morphology after exposure was obtained by a handy scanner, further processed ArcGis software. characterized ten parameters then quantified using principal component analysis. results showed that frequency had influence...
Thermal shrinkage of flame-retardant fabrics under high temperature exposure would result in the change air layer clothing, which can affect thermal protective performance clothing. This paper introduces a new image-based device to characterize fabrics. The was aimed reconstruct three-dimensional (3D) surface morphology based on grayscale images. imaging collecting system designed obtain images thermal-shrinkage Then, MATLAB programming 3D reconstruction algorithm photometric stereo...
