Application of a delaminated kaolin clay base coat onto linerboard provides a barrier coating for a subsequently applied polymer top coat with potential advantages of increased paper stiffness, improved water resistance at reduced polymer overcoat. Motivated by coating material cost reduction, feasibility of the technique is demonstrated by applying a delaminated clay coating online followed by...

Nanocomposite polymer electrolyte membranes (NCPEMs) based on poly(acrylic acid)(PAA) and titania (TiO2) are prepared by a solution casting technique. The ionic conductivity of NCPEMs increases with the weight ratio of TiO2.The highest ionic conductivity of (8.36 ̆ 0.01) ˆ 10 ́4 S ̈ cm ́1 is obtained with addition of 6 wt % of TiO2 at ambient temperature. The complexation between PAA, LiTFSI and T...

The adhesive interactions of block copolymers composed of poly(methyl methacrylate) (PMMA)/poly(acrylic acid) (PAA) and poly(methyl methacrylate)/poly(2-hydroxyethyl methacrylate) (PHEMA) with the proteins fibronectin, bovine serum albumin and collagen were studied by atomic force microscopy. Adhesion experiments were performed both at physiological pH and at a slightly more acidic condition (p...

Novel electrically conducting composite materials consisting of poly(aniline) (PANI) nanoparticles dispersed in a poly(vinyl alcohol) (PVA)-g-poly(acrylic acid) (PAA) hydrogels were prepared within the polymer matrix by in situ polymerization of aniline. The conversion yield of aniline into PANI particles was determined gravimetrically while structural confirmation of the synthesized polymer wa...

Highly flexible nanocomposite hydrogels were prepared by using silica nanoparticles (SNPs) as fillers and multi-functional cross-links to graft hydrophilic poly(acrylic acid) (PAA) by free radical polymerization from an aqueous solution. The SNPs were collected by neighboring polymer chains and dispersed uniformly within a PAA matrix. The mechanical properties of the nanocomposite hydrogels wer...

Novel ionizable polymer networks were prepared from oligo(ethylene glycol) (OEG) multiacrylates and acrylic acid (AA) employing bulk radical photopolymerization techniques. The properties of these materials exhibited a complex dependence on the network structure and composition, and the materials were therefore used in the design of controlled release devices with precisely controlled propertie...

Novel ionizable polymer networks were prepared from oligo(ethylene glycol) (OEG) multiacrylates and acrylic acid (AA), employing bulk radical photopolymerization techniques. The properties of these materials exhibit a complex dependence on the network structure and composition. Dynamic mechanical analysis and penetrant sorption experiments demonstrated that the cross-linked structure of the mat...

Polyelectrolytes (PEs) are widely used in applications such as water purification, wastewater treatment, and mineral recovery. Although much has been learned in past decades about the behavior of PEs in bulk aqueous solutions, their molecular behavior at a surface, and particularly an oil-water interface where many of their applications are most relevant, is largely unknown. From these surface ...

The bifunctional ligand trans-3-(3-pyridyl)acrylic acid has been utilized to promote the formation of a novel hetero-metallic [Cu3(C8H6NO2)6Nd2(NO3)6] (1) and two homometallic: [Nd(C8H6NO2)3H2O] (2) and [Cu(C8H6NO2)2] x H2O (3) metal organic framework (MOF) materials. The philosophy here is that a mixture of hard (Nd3+) and softer metal cations will show preference for the carboxylic and pyridy...
