Lithium battery separators play a critical role in the performance and safety of lithium batteries. In this work, four kinds polymer particle adhesives (G1–G4) for were synthesized via dispersion polymerization, using styrene, butyl acrylate acrylonitrile as monomers. The size/size distributions, morphologies glass transition temperatures (Tg) explored laser size analysis, scanning electron mic...

Adhesive bonding of polymer matrix composites offers various advantages over traditional fasteners, such as a uniform stress state, reduced weight, and delay composite delamination. However, adhesive has limited implementation due to challenges in the prediction durability. This work introduces new method monitor an adhesively bonded joint by dispersing magneto-electric nanoparticles (MENs) int...

Marine mussels secret protein-based adhesives, which enable them to anchor to various surfaces in a saline, intertidal zone. Mussel foot proteins (Mfps) contain a large abundance of a unique, catecholic amino acid, Dopa, in their protein sequences. Catechol offers robust and durable adhesion to various substrate surfaces and contributes to the curing of the adhesive plaques. In this article, we...

OBJECTIVES The objective of this study was to investigate the influence of the chemical structure of methacrylate monomers used in dentin adhesives on degree of conversion (DC), water sorption, and dynamic mechanical properties. MATERIALS AND METHODS Experimental adhesives containing 2,2-bis[4-(2-hydroxy-3-methacryloxypropoxy) phenyl]-propane (BisGMA), 2-hydroxyethyl methacrylate (HEMA), and ...

A unified slip model is developed, which predicts wall slip by either a disentanglement mechanism or by debonding mechanism, depending upon the adhesive energy of the wall-polymer pair. The model is based on the transient network theory, in which the activation processes of adsorption and desorption are considered to occur at the wall in parallel to the stretching of the adsorbed chains. It is ...

We report a simple, low-cost and detachable microfluidic chip incorporating easily accessible paper, glass slides or other polymer films as the chip materials along with adhesive wax as the recycling bonding material. We use a laser to cut through the paper or film to form patterns and then sandwich the paper and film between glass sheets or polymer membranes. The hot-melt adhesive wax can real...

Introduction The presence of proteoglycans, glycosaminoglycans and other glycosylated molecules is responsible for the inherent non-adhesive nature of the endothelial cell glycocalyx that prevents attachment of other cells and biomolecules to the intravascular endothelial cell lining . Mimicking such a sugar-rich structure for vascular interfacial biomaterials provides a way to prevent the clin...

A glue stick is comprised of solidified adhesive mounted in a lipstick-like push-up tube. Whey is a byproduct of cheese making. Direct disposal of whey can cause environmental pollution. The objective of this study was to use whey protein isolate (WPI) as a natural polymer along with polyvinylpyrrolidone (PVP) to develop safe glue sticks. Pre-dissolved WPI solution, PVP, sucrose, 1,2-propanedio...
