Distinct Molecular Structures of Edge and Middle Positions of Plasma Treated Covered Polymer Film Surfaces Relevant in the Microelectronics Industry
Plasma treatment processing is a ubiquitous and necessary processing step in the manufacturing of electronic components. In the semiconductor industry, this processing step is utilized to clean the polymer substrates prior to soldering and applying epoxy underfill resins in flip-chip technology. In this paper, two polymers, polystyrene and polyimide, were protected with a cover and exposed to va...

ChemCommun--Construction of supramolecular polymer by enzyme-triggered covalent condensation of CB[8]-FGG-based supramonomer
A rapid and effective enzymatic strategy for the fabrication of a supramolecular polymer is presented for the first time, in which a bifunctional ternary host–guest supramonomer is first prepared followed by subsequent enzymatic coupling of supramonomers.

Multitemperature Memory Actuation of a Liquid Crystal Polymer Network over a Broad Nematic–Isotropic Phase Transition Induced by Large Strain
The shape change of a polymer actuator based on liquid crystal network (LCN) generally occurs over a relatively sharp LC-isotropic phase transition. Reported herein is the discovery of an unusual phenomenon and the enabled actuation control for LCN. The smectic phase of a LCN with mesogenic moieties on the chain backbone can be suppressed by high elongation of the specimen, which gives rise to a...

Nonisothermal Crystallization, Melting Behaviors, and Mechanical Properties of Isotactic Polypropylene Nucleated with a Liquid Crystalline Polymer
The nonisothermal crystallization and melting behaviors of isotactic polypropylene (iPP) nucleated by a mainchain liquid crystalline polyester (poly(4,4′-bis(6-hydroxyhexyloxy)biphenyl phenylsuccinate), PBDPS) as a β-nucleating agent have been investigated by differential scanning calorimetry (DSC), wide-angle X-ray diffraction (WAXD), and polarizing optical microscopy (POM). The effect of PBD...

[Chin. Chem. Lett.] Polymer brushes on hydrogen-terminated silicon substrates via stable Si-C bond
We demonstrate a straightforward and efficient method for the creation of polymer brushes on hydrogen-terminated silicon substrates through the UV-induced photopolymerization. The surface grafting polymerization is applicable to a series of monomers, allowing the direct formation of homogeneous polymer coatings ranging from hydrophilic poly(2-isopropenyl-2-oxazoline) (PIPOx), amphiphilic poly( N -...

56. [European Polymer Journal] The role of chemical and physical crosslinking in different deformation stages of hybrid hydrogels
Hybrid crosslinking hydrogels have exhibited excellent mechanical properties, however, the relationship between chemical and physical crosslinking in the various deformation stages is still indistinct. Here, we have explored a novel hybrid hydrogel by inducing low density of chemical crosslinking into latex particle hydrogels (LP-Gel), in which latex particles act as physical crosslinking center...

Preparation of Composite Films with Controlled Dispersion State of SiO2 Nanoparticles by Using Polymer/SiO2 Nanocomposite Particles
Dispersion state of inorganic nanoparticles (NPs) in the composite films may significantly influence on the film properties. In the present study, polymer/SiO2 nanocomposite particles (NCPs) with various SiO2 grafting states (various grafting ratios, various linking patterns between SiO2 NPs, and various types of grafted chains), were prepared through in situ emulsion or in situ m...

Synergistic effect of LaL with PE on the thermal stability of poly (vinyl chloride). Polymer Degradation and Stability
The basic complex ([LaL(OH)OH2], abbreviated as LaL) was firstly synthesized by maleic anhydride,ethylenediamine, sodium hydroxide and lanthanum chloride. Its structure was characterized by Fourierinfrared spectrum (FTIR), elemental analysis, nuclear magnetism resonances (NMR) and thermogravimetric analysis (TGA). The obtained LaL was used as a thermal stabilizer on polyvinyl chloride (PVC) and ...

【ACS Applied Materials & Interfaces】Temperature-responsive hierarchical polymer brushes switching from bactericidal to cell repellency
Abstract:
Unlike conventional poly(N-isopropylacrylamide) (PNIPAM)-based surfaces switching from bactericidal activity to bacterial repellency upon decreasing temperature, we developed a hierarchical polymer architecture, which could maintain bactericidal activities at room temperature while presenting bacterial repellency at physiological temperature. In this architecture, a thermoresponsive...
