Polymer Microsieves Manufactured by Inkjet Technology
Langmuir, 2008Liquid sessile drops can be used as sacrificial templates for the creation of pores in polymeric microsieves. Using inkjet printing, we deposit sessile drops of a water-based liquid onto a hydrophobic solid support and cover them with a thin liquid layer of a polymer solution in such a way that the sessile drops penetrate through the top interface of ...

Additive manufacturing of polymer-derived ceramics
Science, 2016Printing ceramics into complex shapes Some materials, such as thermoplastics and metals, are naturally suited to being 3D printed because the individual particles can be fused together by applying heat. In contrast, ceramics do not fuse together the same way. Eckel et al.

Interfaces in repair, recycling, joining and manufacturing of polymers and polymer composites
Journal of Applied Polymer Science, 1999A basic set of 10 thermoset polymer–polymer interfaces has been identified to play a vital role in the technical and economic aspects of composite manufacturing (RIM/RTM, compression molding, autoclave lamination), recycling, repair, welding, and joining of polymer composites.

Additives for the Manufacture and Processing of Polymers
2009Plastic additives are a diverse group of specialty chemicals that are used to manufacture polymers (polymerization aids like initiators, surfactants and protective colloids) or are incorporated into the plastic product prior to or during processing. They may become part of the polymer network (like initiators do) or remain without a chemical linkage to

Consistent Manufacturing Device for Coiled Polymer Actuators
IEEE/ASME Transactions on Mechatronics, 2018Coiled polymer actuators are fabricated by heating a twisted nylon fishing filament. This paper provides a detailed review of their manufacturing process and proposes a method to manufacture these actuators consistently to improve the predictability of their behavior.

Manufacturing of a Shape Memory Polymer Actuator
Volume 1: Processing, 2015Shape memory polymer (SMP) foams can be used to manufacture actuators with tailored actuation rate. Being related to foam shape recovery by heating, SMP actuator operates by conversion of heat into motion. In the current study, a SMP linear actuator has been manufactured which is able to apply a maximum load of 50 N (depending on the recovery ...

Manufacturing and Investigation of the MWCNT/Polymer Nanocomposites
Solid State Phenomena, 2009Multiwall carbon nanotube (MWCNT) reinforced polyvinylacetate nanocomposites (PVAc) have been investigated. Optimal technological parameters for manufacturing of the PVAc/MWCNT nanocomposites by solution casting are defined. Some physical, calorimetric, thermo gravimetric and electrical properties of the investigated PVAc/MWCNT nanocomposites are ...

Electrically Conductive Polymers for Additive Manufacturing
ACS Applied Materials & InterfacesThe use of electrically conductive polymers (CPs) in the development of electronic devices has attracted significant interest due to their unique intrinsic properties, which result from the synergistic combination of physicochemical properties in conventional polymers with the electronic properties of metals or semiconductors. Most conventional methods
