Fused deposition modeling (FDM) is a rapidly growing 3D printing technology. However, printing materials are restricted to acrylonitrile butadiene styrene (ABS) or poly (lactic acid) (PLA) in most Fused deposition modeling (FDM) equipment. Here, we report on a new high-performance printing material, polyether-ether-ketone (PEEK), which could surmount these shortcomings. This paper is devoted to...

An investigation has been made of the effects from a compatibilizer, viz. carboxylated nitrile rubber (XNBR), on several properties of nitrile rubber (NBR) and acrylic rubber (ACM) blends, including curing characteristics, mechanical, dynamic mechanical and dielectric properties. The presence of XNBR until 10 phr resulted in an improvement of the ultimate tensile properties, especially elongati...

Advancement in thermal three-dimensional printing techniques has greatly increased the possible applications of various materials in medical applications and tissue engineering. Yet, potential toxic effects on primary human cells have been rarely investigated. Therefore, we compared four materials commonly used in thermal printing for bioengineering, namely thermally printed acrylonitrile butad...

Nitrile butadiene rubber (NBR) latex/graphene oxide (GO) membranes were fabricated through a latex compounding and curing method which is relatively new to produce for wastewater treatment. Hence, the steps in production of membrane this approach need be evaluated optimize performance membrane. In paper, effect sulfur loading range 0.5 1.5 parts per hundred (phr) on morphology, crosslink densit...

background: the measurement data regarding the influent and effluent of wastewater treatment plant (wwtp) provides a general overview, demonstrating an overall performance of wwtp. nevertheless, these data do not provide the suitable operational information for the optimization of individual units involved in a wwtp. a full-scale evolution of wwtp was carried out in this study via a reconciled ...

Abstract In this study, three-layer molecular models of frictional pair containing nitrile-butadiene rubber matrix reinforced by nano-ZnO particle as the core and Fe layers counterparts are first developed. Molecular dynamics simulations then conducted to explore enhanced effects on tribological behaviors NBR matrix. The simulation results show that coefficient can be efficiently reduced approx...

In the present work, thermoplastic elastomeric nanofibers made up of a homogenous blend nitrile butadiene rubber (NBR) and Ppolycaprolactone (CL), with 80% wt rubbery component, are used to modify carbon fiber reinforced polymer (CFRP) laminate aim improving its delamination damping behavior at same time. Since nanofibrous membrane is not chemically cross-linked, fibrous morphology lost during ...
