The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature. 1163-19-5, Name is 6,6′-Oxybis(1,2,3,4,5-pentabromobenzene), SMILES is BrC1=C(Br)C(Br)=C(Br)C(Br)=C1OC2=C(Br)C(Br)=C(Br)C(Br)=C2Br, in an article , author is Wang, Yuan, once mentioned of 1163-19-5, Formula: C12Br10O.
Poly ether ether ketone and its composite powder prepared by thermally induced phase separation for high temperature selective laser sintering
Selective Laser Sintering (SLS) is one of the advanced additive manufacturing technologies which can build the geometrically complex structure from a three-dimensional CAD model. Poly ether ether ketone (PEEK) is one of the available materials for SLS and has received numerous interesting due to its excellent properties. In this research, a novel approach, thermally induced phase separation (TIPS) was employed to produce neat PEEK and PEEK/CNT composite powders with near spherical shape, desired particle size and size distribution for SLS application. Powders produced by TIPS demonstrated good flowability and processability. SEM images proved that CNT was embedded in PEEK powder. PEEK/CNT composite powder had shown an increased crystallinity in comparison with neat PEEK powder. Sintering rate of produced powders were studied with hot stage microscopy. Single layer films were built successfully by high temperature selective laser sintering (HT-SLS) using the powder developed via TIPS. Thermodynamics characteristics of single layer films were studied by DMA. Results revealed that addition of 0.1% CNT improved both storage and loss modulus of PEEK. (c) 2021 The Authors.
