When one brings "polymeric materials" and "mechanical action" into the same conversation, topic of this discussion might naturally focus on everyday circumstances such as failure fibers, fatigue composites, abrasion coatings, etc. This intuitive viewpoint reflects historic consensus in both academia industry that mechanically induced chemical changes are destructive, leading to polymer degradation limits materials lifetime macroscopic molecular levels. In 1930s, Staudinger observed...
Silica nanoparticles grafted with poly(methyl acrylate) (PMA) chains anchored by a maleimide-anthracene cycloadduct were synthesized to demonstrate mechanochemically selective activation of mechanophores at heterogeneous interfaces. By quantifying the anthracene-containing cleaved PMA polymers, which are generated via retro-[4 + 2] cycloaddition reactions, first-order kinetic coefficient was determined. Activation characteristics nanoparticle exhibit behavior similar mechanophore-linked...
Supramolecular conjugation between native protein concanavalin A (ConA) and synthetic polymer PEG (polyethylene glycol) was achieved by dual molecular recognition interactions via a linker, βCD-Man, of which β-cyclodextrin (βCD) α-mannopyranoside (Man) recognized the adamantane (Ada) end lectin ConA orthogonally. Further self-assembly resultant supra-conjugates ConA-PEG induced addition αCD, selectively threaded chains, leading to nanoparticles in dilute solution or hydrogel at higher...
Efficient encapsulation of tetraethylenepentamine (TEPA), as an example aliphatic amine, was achieved by emulsion-templated, in situ polymerization. Hydrophobically modified clay nanoplatelets were employed emulsifiers to obtain water-in-oil (W/O) dispersions followed interfacial polymerization between a portion the TEPA cargo and polymethylene polyphenylene isocyanate (PMPPI). The resultant capsules exhibit spherical shape, desirable thermal stability, modest barrier properties,...
Silica nanoparticles grafted with poly(methyl acrylate) chains whose anchor points are maleimide-anthracene cycloadducts were prepared at various grafting densities to demonstrate fundamental characteristics of mechanophore activation heterointerfaces. The monotonically decreasing correlation between polymer density and surface-bound was quantitatively elucidated discussed. Presumably as a result polymer-polymer interactions, plays significant role in heterogeneous activation. findings...
A new nanomaterial or nano-filler in the form of multiwalled carbon nanotube-zinc oxide (MWCNT-ZnO) was synthesized for purpose modifying poly(butylene adipate-co-terephthalate) (PBAT) and its derivative (modified PBAT MPBAT) through a melt-blending method (MPBAT obtained by introducing maleic anhydride groups into PBAT). The effect on properties resultant nanocomposites determined from characterization mechanical properties, morphology, crystallinity, thermal stability, barrier...
Inorganic nanoparticles can self-assemble into various supra-structures, among which vesicles are seldom reported. In this paper, a reversible self-assembly of gold to vesicles, mediated by double hydrophilic block copolymers, was carried out in pure water under the stimulus temperature.
Abstract A facile and efficient strategy for preparing well dispersed graphene oxide (GO)‐ co ‐Poly(phenylene benzobisoxazole) (PBO) copolymer fibers was carried out by direct in situ polycondensation of composite inner salts. The salts were achieved to improve the dispersivity, solubility, reactivity, interfacial adhesion GO PBO polymer matrix. structure morphology GO‐ ‐PBO have been characterized. It demonstrated that covalently incorporated with molecular chains considerably fiber even...
A series of aromatic polysulfonamides with various monomer ratios 4,4′-diaminodiphenylsulfone (p-DDS) and 3,3′-diaminodiphenylsulfone (m-DDS) were synthesized to investigate the relationship between copolymer composition their properties. The was determined from nuclear magnetic resonance (NMR). It found that varied little ratio; thus, similar reactivity two diaminodiphenylsulfones shown by results. From analysis thermal properties polysulfonamides, high stability copolymers both in N2 air...
By assuming that a reaction is mainly single-radical chain termination, the mechanism, for solid-phase radical graft polymerization of acrylic acid (AA) onto polypropylene (PP), was analyzed based on our previous experimental data. The Monte Carlo simulation technique employed to investigate kinetics solid phase determine kinetic rate constants all elementary reactions. simulated total amount radicals, which only increases quickly at start reaction, indicates stationary state assumption...
In order to solve the problems of traditional safety training in industrial field, such as boring content, no practical operation and effective quality evaluation method, a virtual ergonomics system for production based on visible light communication is proposed. It includes 5 function modules: risk identification module, accident simulation emergency drill module ergonomic module. addition, this paper conducts series experiments verify feasibility validity using electrocardiograph (ECG)...
There is a growing trend in incorporating biomass-based engineered nanomaterials into food products to enhance their quality and functionality. The zeta potential, droplet size, microstructure, content of free fatty acid (FFA) release were determined investigate the influence plant-derived particle stabilizer, i.e., lignin-containing cellulose nanofibrils (LCNFs). Remarkable differences observed during digestion stages, which found be correlated with concentrations LCNFs. gradual FFA small...
