Abstract This paper describes a method for aligning stiff, high-aspect-ratio microcrystals over macro-length scales using polymer fiber drawing process. A composite preform was constructed with an interfacial, liquid shell layer of grapeseed oil suspending ytterbium-doped potassium lutetium fluoride (30% Yb:K 2 LuF 5 , KLF) between adjacent cylindrical surfaces acrylic (polymethyl methacrylate,...

Sulfo and carboxyl group-containing polymers polymer/silica adsorbents poly(acrylonitrile-co-2-acrylamido-2-methylpropane-1-sulfonic acid-co-acrylic acid-co-N,N’-methylene-bis-acrylamide) [poly(AN-co-AMPS-co-AAco-MBA)] poly(AN-co-AMPS-co-AA-co-MBA)/SiO2 were synthesized by a UV-initiated polymerization or simultaneous in situ sol-gel process used as for removal of Co(II) Ni(II) ions from aqueou...

The low-kinetic energy collision-induced dissociation (CID) behavior of different sodium-cationized polylactide (PLA) oligomers was thoroughly investigated to shed some light on the analytical potentialities of CID experiments in the context of polymer characterization. Indeed, investigation of several end-groups modified PLA reveals that, in addition to the expected end-group specific dissocia...

The chemorheology of poly (methacrylamide-co-acrylic acid) gel crosslinked by Chromium (III) (Cr ) III ions was investigated using stress-controlled viscometry techniques. This work showed that between various variables, such as polymer and crosslinker concentrations, salinity, pH and temperature, the later parameter had a significant effect on the idle time and processing time as two critical ...

We demonstrate the selective functionalization of 3-D polymer microstructures that were created using multiphoton absorption polymerization. By fabricating different portions of the structures with acrylic and methacrylic polymers, we are able to take advantage of the differential reactivities of these materials to perform functionalization chemistry on a single polymeric component. We demonstr...

This paper describes a sensor employing a gel formed from an interpenetrating polymer network of poly(vinyl alcohol) and a copolymer of N-isopropylacrylamide and acrylic acid. This gel exhibits a continuous volume-phase transition that is strongly dependent on the presence of polyvalent metal ions in the gel solvent. A sensor apparatus has been constructed that estimates, in real time, the tran...

Poly(acrylic acid) polyelectrolyte brushes were synthesized by surface-initiated atom transfer radical polymerization (SI-ATRP) of tert-butyl acrylate on planar gold surfaces and subsequent hydrolysis. Three types of monolayers with different numbers of thiol binding sites per initiating unit were used. The binding strength to the gold surface turned out to be of crucial importance for the form...

Coating and lamination are two functional processes which are used make a proper finishing to the textile material. The coating formulation with different textile grade polymer like PVC, PU, acrylic, PTFE are hugely used to make a textile product with multipurpose way likewaterproof protective clothing, tarpaulin, protective clothing, electrical insulation etc. on the other hand lamination proc...

Abstract Acrylic is a kind of polymer material and gradually applied to load-bearing components. The working stress ultimate bearing capacity the acrylic structure are main design indexes. Aiming at world’s largest spherical vessel, structural design, finite element analysis full-size prototype tensile test new connection node were carried out in this paper. This will bear 90 kN tension force f...
