Microfluidic devices were developed that integrate the synthesis of well defined block copolymers and dynamic light scattering (DLS) measurement of their micelle formation. These metal devices were designed to operate in contact with organic solvents and elevated temperatures for long periods, and thus were capable of continuous in-channel atom transfer radical polymerization (ATRP) of styrene ...

A low-intensity (6 W) light-emitting diode (LED) effectively activated an organotellurium chain transfer agent and the dormant species, promoting well-controlled radical polymerization. The use of the LED provided many advantages over the previously reported high-intensity Hg lamp, including high energy efficiency during the polymerization, and easy availability of the low-cost light source. St...

In the simplest case, vinyl monomers are named by using the prefix poly in front of the monomer name, e.g. polyethylene. When a monomer name consists of more than one word, or if the name is preceded by a number or letter, the monomer name is placed in parentheses after the word poly, e.g. poly(acrylic acid) or poly(methyl methacrylate). In general, common names of monomers are used rather than...

Admittance spectroscopy is employed to explain the property differences observe between organic thin film transistors (OTFTs) fabricated with various gate insulator layers based on poly(4-vinylphenol) (PVP) and poly(methyl methacrylate) (PMMA). The objective achieved through development of an equivalent circuit a compact analytical model device core structure, namely, metal–insulator–semiconduc...

Bone cement, frequently based on poly (methyl methacrylate), is commonly used in different arthroplasty surgical procedures and its use essential for prosthesis fixation. However, manufacturing process reaches high temperatures (up to 120 °C), producing necrosis the patients’ surrounding tissues. To help avoid this problem, addition of graphene could delay polymerisation methyl methacrylate as ...

Phase change materials (PCMs) have great promise in many fields related to energy utilization and thermal management. However, PCMs face challenges large-scale applications due the intrinsic melting leakage, low conductivity poor photothermal conversion. Herein, nanoencapsulated phase (NanoPCMs) were fabricated by RAFT miniemulsion polymerization using quaternized poly(2-(dimethylamino)ethyl me...

The poly(methyl methacrylate) (PMMA)/poly(methyl methacrylate)–poly(methyl acrylate acid) copolymer (PMMA–PMAA) composite polymer latex were synthesized by the method of soapless seeded emulsion polymerization. The morphology of the composite polymer latex was core–shell structure. The core was PMMA and shell was PMMA–PMAA copolymer. Because the PMMA–PMAA copolymer was shell, the carboxylic aci...

The structural characterization of copolymers by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOFMS) remains a challenging task, since their random comonomer distribution creates very complicated mass spectra. In this study, a high-resolution TOF mass spectrometer with a spiral ion trajectory was applied to the structural and compositional characterization...
