Summary: The study investigated the effects of different forms of rosin ester resin on the properties of pressure-sensitive adhesives, revealing that agglomerated particles and dissolved molecules of the resin have different impacts on cohesive strength, tack, and fracture energy of the adhesive. The glass transition temperature of the adhesive also increased with higher molecular weights of the resin.

Summary: The study found that the cross-linked polymer B performs better than A in some aspects, such as a higher tack peak temperature and better wettability and deformability of PSA. Through dynamic mechanical analysis and nuclear magnetic resonance measurements, it was discovered that the lower G' of B is due to its weaker intermolecular interactions.

Summary: Investigation on probes with suitable shapes and surface roughnesses for a probe tack test on pressure-sensitive adhesive (PSA) revealed that a smooth, polished probe slightly convex at the center demonstrated superior performance compared to a flat-ended probe. High surface roughness decreased tack. Observations on debonding showed that fibrillation started from the edge of the probe and spread to the center, with the fibril growing without peeling until reaching the peak of the force-displacement curve, followed by simultaneous fibril growth and peeling. The study also highlighted the importance of fibrillation in tack development and investigated the necessary test conditions to observe the deformation behavior of PSA tape with sufficient interfacial adhesion. A preheating method involving contacting the probe and PSA tape, followed by cooling, was found to be useful for characterizing PSAs. A comparison between crosslinked random copolymers poly(n-butyl acrylate-acrylic acid) (A) and poly(2-ethylhexyl acrylate-acrylic acid) (B) demonstrated that copolymer B exhibited better interfacial adhesion and deformability, with the presence of a fibrillation shoulder after the peak in the force-displacement curve.

Summary: By treating the surfaces of polystyrene and polyamide 12 with O-2 plasma, the number of polar groups capable of hydrogen bond formation was increased, allowing for the joining of incompatible substrates without adhesive by pressing them together. The adhesion strength increased with bonding temperature and both substrates being plasma-treated, reaching adhesive strengths up to 5.5 +/- 1.7 MPa. Additionally, the joint substrates could be rapidly de-bonded on demand simply by treatment with water, and re-bonded by renewed plasma treatment.

Summary: This study presents a novel approach for morphology construction in an organic-inorganic composite system, achieving superior microwave absorption. The metallopolymeric superstructures (MPS) grown on Nd2Fe14B particles surface through chemical and physical synthesis methods exhibit a special flower-like appearance and enhance the electromagnetic response capability of the composite material. Adjusting the content of MPS can significantly improve the maximum reflection loss of the composite, leading to a broader effective absorption bandwidth at a low matching thickness, showing great potential for microwave absorption applications.
