A chemically defined thermoresponsive hydrogel, poly(AEtMA-Cl-co-DEAEA) cross-linked with N,N'-methylenebisacrylamide, which allows enzyme-free passaging, was used as a substrate to culture murine embryonic stem cells (mESCs) under defined and undefined conditions. Analysis of 14 stem cell markers showed that the mESCs remained in a "naïve" state of pluripotency with differentiation potential t...

Hydrogels based on N-isopropylacrylamide and sodium acrylate as ionic comonomer were synthesized by free radical polymerization in water using N,N'-methylenebisacrylamide as crosslinker and ammonium persulfate as initiator. The glass transition of dried copolymers poly(N-isopropylacrylamide) (PNIPA) and poly(sodium acrylate) (SA) gels and demixing/mixing transition of PNIPA-SA hydrogels swollen...

crosslinked poly(acrylic acid)s were prepared using two types of crosslinker by precipitation polymerization method in a binary organic solvent. n,n’-methylenebisacrylamide (mba) and polyethylene glycol dimethacrylate (pegdma-330) were used as low-molecular weight and long-chain crosslinkers, respectively. the effect of various types of crosslinkers on polymer characteristics (i.e., gel content...

In this work, a novel superabsorbent hydrogel composite based on collagen have been prepared via graft copolymerization of methacrylic acid (MAA) in the presence of kaolin powder by using methylenebisacrylamide (MBA) as a crosslinking agent and ammonium persulphate (APS) as an initiator. A proposed mechanism for hydrogel formation was suggested and the structure of the composite was established...

A facile strategy was developed here to prepare cross-linked polymeric nanocapsules (CP nanocapsules) with silica nanoparticles as templates. The silica nanoparticle@cross-linked polymer nanoparticles were prepared by the encapsulation of the silica nanoparticles by the one-pot approach via surface-initiated atom transfer radical polymerization of hydroxyethyl acrylate in the presence of N,N'-m...

The main objective of this study is to prepare, thermally, sensitive microgel particles bearing thiol groups via precipitation polymerization of N-isopropylacrylamide (NIPAM), methylenebisacrylamide (MBA) and vinylbenzylisothiouronium chloride (VBIC) using 2-2'-azobis(2-amidinopropane)-dihydrochloride (V50) as initiator. The influence of various parameters has been investigated as a systematic ...

We report the development of a novel method for functionalizing polymerized crystalline colloidal arrays (PCCA). This new method enables us to easily incorporate molecular recognition agents into the PCCA to produce chemical sensing materials that report on analyte concentration via diffraction of visible light. We copolymerize glycidyl methacrylate with acrylamide and N,N′-methylenebisacrylami...

Due to the low content of adsorption-active groups in lignin, its application field adsorption is limited. Herein, we first prepared cationic kraft lignin acrylate, from which a (CKLA) hydrogel was further by acrylamide, and N, N’-methylenebisacrylamide. The morphology, compression properties swelling CKLA hydrogels were investigated. applied as an adsorbent for Congo red. effect dosages, initi...
