Synthesis and characterization of polycarboxylate superplasticizer for cementitious systems: a GPC, FTIR, and SEM study

Synthesis and cement performance of thermoresponsive core–shell microgel superplasticizers with size modulation

Four microgels (MG) with different carboxyl contents were designed and prepared by using two monomers of methacrylic acid (MAAc), the thermosensitive monomer N-isopropylacrylamide (NIPAM), and the crosslinker N,N′-methylenebisacrylamide (BIS). NH2-functionalized HPEG2400 (HPEG-NH2) was grafted onto the carboxyl groups...

New Polyurethane Biocomposites Based on Cellulosic Fibers: Effect of the Cellulose Content on the Composite Thermomechanical Properties

Two polyurethane (PU) matrices were synthesized using poly(ε‐caprolactone) diol and 4,4′‐diisocyanato dicyclohexylmethane using two different synthetic approaches. NMR and FTIR spectroscopy analysis ensured the chemical structure and the formation of the matrices. Thereafter, composite materials were prepared by in...

Structure and flory-rehner analysis of organo-inorganic superabsorbent nanocomposites based on acrylic monomers and montmorillonite clay

Synthesis and characterization of PVA-co-acrylic acid incorporating magnesium nanoparticles and their application in sweetening of natural gas.

Interactions Among MWCNTs, an Air-Entraining Agent, and Superplasticizers in Lightweight Cementitious Materials

This study examined the combined effects on highly foamed cementitious materials of varying concentrations of multi-walled carbon nanotubes (MWCNTs), an air-entraining agent (AEA), and three superplasticizers (SPs): a lignosulfonate-based superplasticizer (SP-LS), a polyacrylate-based superplasticizer (SP-PA), and a po...

Photocrosslinked PEG-PVP-Pullulan Composites Reinforced With Brushite: A Preliminary Bone-Facing Material for Osteochondral Tissue Engineering

Objectives: The development of biomaterials for bone tissue engineering requires a combination of suitable mechanical properties, bioactivity, and cytocompatibility. In this study, photocrosslinked polymer-ceramic composites based on poly(vinylpyrrolidone) (PVP), poly(ethylene glycol) (PEG), and pullulan were developed...
