Tuning the properties of segmented polyurea by regulating soft-segment length

ABSTRACT

Polyurea is being widely advocated as a “retrofit” coating on structures, which mandate protection against blast. The physical properties of polyurea can be tuned by judicious choice of reactants, and the processing methodology employed for its preparation. 169 more words

Antibacterial silicylacrylate copolymer emulsion for antifouling coatings

Abstract

Employing silicylacrylate and cationic acrylate as functional monomers, a novel silicylacrylate copolymer (SAC) antibacterial emulsion was successfully synthesized by soap-free emulsion polymerization. The effect of functional monomers, initiator and temperature on stability and antibacterial activity of SAC emulsion were investigated. 131 more words

Novel self-healing anticorrosion coating based on L-valine and MBT-loaded halloysite nanotubes

Abstract

This work creatively utilized the pH-dependent electrostatic interactions between L-valine (L-Val) and halloysite nanotubes (HNTs) to fabricate pH-responsive anticorrosion materials and compared with 2-mercaptobenzothiazole (MBT)-loaded HNTs, which were assembled via layer-by-layer (LbL) self-assembly. 175 more words

Non-covalent functionalized multi-wall carbon nanotubes filled epoxy composites: Effect on corrosion protection and tribological performance

Abstract

To enhance the dispersion of multi-walled carbon nanotubes (MWCNTs) in epoxy matrix, poly(2-butylaniline) (PBA) was employed as a dispersant to disperse the MWCNTs via non-covalent functionalization. 120 more words

Biomass polymeric microspheres containing aldehyde groups: Immobilizing and controlled-releasing amino acids as green metal corrosion inhibitor

Abstract

This article reports a novel type of aldehyde-containing microspheres (ACMs) prepared by suspension polymerization using two biomass monomers, syringaldehyde methacrylate (SMA) and eugenol methacrylate (EMA), in which SMA provides aldehyde groups and EMA provides crosslinking structure. 157 more words

Self-, co-organisation behaviour and encapsulation efficiency of waterborne polyurethane pre–polymers

Abstract

Polyurethane-prepolymers are the precursor for waterborne polyurethane coating applications. The physical-chemical behavior of the pre-polymers are worth thorough investigation, since they will largely influence the final properties of coating products  0005; 0010 ;  0015. 141 more words
