Vitrimers make up a class of polymeric materials combining the advantages thermosets and thermoplastics, because they can be reprocessed while being at same time permanently cross-linked. However, long heating duration or an elevated temperature is necessary for most vitrimers to relax stress from deformation exhibit malleability. Herein, disulfide-containing carboxylic acid applied as curing agent synthesize epoxy with simultaneous disulfide metathesis carboxylate transesterification. The...
Vitrimer materials that obscure the line between ″thermoset″ and ″thermoplastic″ have already attracted a great deal of interest since they exhibit dynamic properties stress relaxation or reprocessability without losing their permanently cross-linked networks. While much research has been aimed at developing new exchangeable bonds to broaden scope, there is dearth effort in exploring key factors influence vitrimer materials. These explorations are not only useful exact design synthesis but...
By introducing methanol as a co-solvent into cyclopentanone, solvent effects on structure, photoresponse and speed of gelation dicholesterol-linked azobenzene organogel DCAZO2 have been investigated. Optical microscopy (OM) scanning electron (SEM) images reveal that the gel fibers form macroscopic aggregates by adding methanol. Minimum concentration (MGC) gels decreases with increasing content, while gel-to-sol transition temperature (Tgel) firstly increases afterwards. For...
A series of new symmetric dicholesterol-linked azobenzene gelators with different spacer lengths have been synthesized. The compounds spacers zero, two or six methylene units are denoted as DCAZO0, DCAZO2 and DCAZO6, respectively. gelation test reveals that a subtle change in the length can produce dramatic behavior compounds. obtains minimum concentration among three gelators. For cyclopentanone gel DCAZO2, reversible gel–sol transitions by irradiation UV visible light investigated UV-vis...
A conductive ternary network structure composed of AgNWs/AgNPs based on a polydopamine-modified 3D PU sponge was fabricated, which shows excellent electromechanical ability owing to the combined effects from network.
Mechanochromic polymers exhibit potential applications in damage reporting and stress sensing. Despite the rapid progress achieved recent years, mechanochromic structural polymers, such as epoxy thermosets, remain difficult to develop, let alone materials that can distinguish different levels of by a visual color change. This work presents new class multicolor thermosets discriminate between low high compressive stresses via incorporation two distinct mechanophores. Amino-functionalized...
The AME and net energy (NE) values of 4 corn varieties, including 2 normal varieties (Zheng Dan 958 Xian Yu 335), one each waxy sweet corn, soybean meal samples regular (RSBM) dehulled (DSBM), were determined in experiments for broiler breeding cocks using the indirect calorimetry method. test diets Experiment 1 consisted which replaced 40% corn-soybean basal diet, contained 25% RSBM or DSBM, was used to replace diet. Thirty (Experiment 1) 18 2) 50-week-old Arbor Acre (AA) a completely...
Interfacial bonding strength of an epoxy-based adhesive depends on the interfacial interaction between and substrate. Normally, curing process at interface accompanied by formation is different from that in bulk, it still a big challenge to probe molecular level. In this study, trace structural evolution representative formula epoxy (digylcidyl ether biphenyl A, DGEBA) amine hardener [1,2-bis(2-aminoethoxy)ethane, EDDA] with sapphire silica substrates upon post-curing steps, sum frequency...
The development of new materials for fast and sensitive protease assay is in demand timely diagnosis diseases, such as cardiovascular disease, cancers, Alzheimer disease. Herein, poly(methacrylic acid) (PMAA) brushes were synthesized from the surfaces silica nanoparticles via surface-initiated atom transfer radical polymerization (ATRP), functionalized with series proteolytically cleavable peptides highly assay. Upon proteolytic cleavage peptides, a short peptide fragment fluorescent tag...
A stretchable conductor was explored by embedding a binary structure fabricated from an interconnected porous of cotton as skeleton along with supported 2D AgNWs network into PDMS, which showed excellent electrical and mechanical properties.
The formation of the interfacial adhesion between an epoxy adhesive and a substrate was normally accompanied by curing process on substrate. Although debate mechanism is still ongoing, this issue can causally be resolved studying structural Herein, to reveal representative formula composed (digylcidyl ether biphenyl A, DGEBA) amine hardener (2,2'-(ethylenedioxy) diethylamine, EDDA) with steel upon postcuring treatments, sum-frequency generation (SFG) vibrational spectroscopy sandwiched...
Bonding is widely used in aircraft and vehicles due to its light weight simple process, but strength decreases sharply hot humid environments. Anodization treatment, for enhancing aging performance, environmentally harmful unsuitable steel. In this study, a catechol-modified epoxy adhesive (CMEA) was prepared on hectogram scale. Comparative analysis with phenol-modified (PMEA) pristine (EA) revealed that the underwater bonding of CMEA (13.0 MPa) stainless steel (SS) significantly...

A photoresponsive azobenzene molecule DCAZO2 with two cholesteryl groups linked to both sides of the group is doped in a mixture nematic liquid crystal E7 and chiral dopant S811 (61.9 wt% E7, 36.1 2.0 DCAZO2). Cooled from isotropic phase 33.0°C, (N*LC) was formed sample then temperature kept unchanged at 33.0°C. UV light irradiation induces trans–cis photoisomerisation thus an obvious transition. When isomerise cis-saturated state, turned off white on same time. The bent-shaped cis isomer...
In order to obtain epoxy compounds with excellent mechanical properties without compromising other desired properties, pristine- or carboxyl-functionalized multi-walled carbon nanotube (p-MWCNT f-MWCNT) along polysulfide were incorporated into an amine-cured resin. Fourier transform infrared spectroscopy and X-ray photoelectron analyses proved the existence of carboxyl groups on surface f-MWCNT. Adding 0.1 wt% f-MWCNT significantly improved tensile strength impact nanocomposites by 104% 47%,...
