Abstract We describe a simplified method to synthesize film forming polymer Janus particles by phase separation during RAFT-based free radical emulsion polymerization. Fully crosslinked snowman- or football-shaped polystyrene (PSJPs) were first produced in one-step batch process using amphiphilic triblock macro-RAFT copolymers as stabilizers. Such turn employed seeds continuous polymerization w...

UV-curable polymer composites are of importance in industry, biomedical applications, scientific fields, and daily life. Outstanding physical properties of polymer composites were achieved with nanoparticles as filler, primarily in enhancing mechanical strength or barrier properties. Structure-property relationships of the resulting nanocomposites are dictated by the polymer-filler molecular ar...

This work aims to produce a 3D-printable bio-based filament composed of high-density polyethylene (HDPE) and chemically modified cellulose nanofibrils. Printing using HDPE as raw material is challenging due its massive shrinkage warping problems. paper presents new method overcome those difficulties by enhancing the mechanical properties achieving better print quality. was achieved nanofibrils ...

Following the modern and extremely useful direction of research development polymer nanocomposites with combined effects photopolymerization superimposed by plasmon-induced processes, we investigated acrylate-based broadband sensitive Irgaqure784 initiator silicon oxide as well gold nanoparticles in different regimes illumination. The details photodecomposition chain formation mechanisms at pre...

A methacrylic-acrylic polymer was synthesised for use as a non-plasticised membrane for hydrogen ion-selective sensor incorporating tridodecylamine as an ionophore. The copolymer consisted of methyl methacrylate and n-butyl acrylate monomers in a ratio of 2:8. Characterisation of the copolymer using FTNMR demonstrated that the amount of each monomer incorporated during solution polymerisation w...

Biological tissue transparency combined with light-sheet fluorescence microscopy is a useful method for studying the neural structure of biological tissues. The development of light-sheet fluorescence microscopy also promotes progress in biological tissue clearing methods. The current clarifying methods mostly use liquid reagent to denature protein or remove lipids first, to eliminate or reduce...

Physically crosslinked hydrogels consisting of polyacrylamide (Aam) and polyoctadecylacrylate (C18A) blocks, leading to hydrophilic hydrophobic domains respectively, are prepared by micellar polymerization. A multifunctional monomer (divinylbenzene, DVB), is also employed create branched chains. The effect the polymer composition amount branching agent on material characteristics evaluated. mel...

A fluorophore-enriched polymer was synthesized through modification of a kind of copolymer by fluorescein isothiocyanate (FITC). The copolymer was obtained by batch emulsion polymerization of t-butyl acrylate (t-BA) and an amino-containing monomer M2, which was produced in our laboratory. According to various characterizations, such as gel permeability chromatography (GPC), H-NMR, fluorescence ...

Clinically available injectable hydrogels face technical challenges associated with swelling after injection and toxicity from unreacted constituents that impede their performance as surgical biomaterials. To overcome these challenges, we developed a system where chemical gelation was controlled by a conjugate Michael addition between thiol and acrylate in aqueous media, with 97 % monomer conve...

Ethyl Acrylate was grafted onto chitosan by using the ceric ammonium nitrate as the initiator. The effect of initiator concentration, monomer concentration, time & temperature on % G and % E were studied. The grafted samples were characterized using FTIR, SEM, atomic force microscopy AFM and XRD methods. Xray diffraction showed changes in the crystallinity pattern of chitosan after the copolyme...
