Novel, fully biobased shape memory thermoplastic vulcanizates (TPVs) were prepared using two sustainable biopolymers, poly(lactic acid) (PLA), and modified natural Eucommia ulmoides gum (EUG-g-GMA), via a dynamic vulcanization technique. Simultaneously, in situ compatibilization was achieved the TPVs to improve interfacial adhesion crosslinked (EUG) “netlike” continuous state PLA matrix form “sea-sea” phase structure. The promoted interface co-continuous structure played critical roles...
Eucommia ulmoides gum (EUG) is a renewable and sustainable polymer, which could be used as rubber or plastic by altering its crosslinking density while the complicated extracting process nonpolar molecular chains limited application. In this effort, novel extraction method was introduced, simplify of EUG. Then, extracted EUG‐chloroform (CHCl 3 ) solution directly to prepare epoxidized EUG (EEUG) with an epoxy degree 40.0% improve polarity. The natural exhibiting both polar motives had...
Abstract In the tread compound of Green tire, silica dispersity is critical for obtaining high‐performance rubber composites. Ionic liquids have been successfully applied in improving through chemical and physical interaction. However, recent research has found that ionic are harmful to ecological environment. Meanwhile, price them high. this paper, deep eutectic solvents (DESs‐Choline Chloride: urea) was synthesized successfully. Then it directly introduced prepare silica‐filled...
In this work, Ge 2 Sb Te 5 (GST) thin films are irradiated by a 1064 nm pulsed laser heat treatment system with different beam profiles. The surface effects induced conditions studied systematically atomic force microscope, spectroscopic ellipsometry, and Raman spectroscopy. It is found that top-hat profile uniform intensity distribution demonstrates the advantages of non-destructive homogeneous surface, which critical for large-scale processing uniformity. threshold fluence amorphization...
As a skeleton material, polyester (PET) fiber can significantly improve the strength and durability of rubber composites, but interfacial adhesion between is poor due to chemical inertia PET surface. Resorcinol-formaldehyde-latex (RFL) impregnating solution usually used treat fibers, RFL contains toxic components such as resorcinol, which harmful human body. A simple less resin-impregnating system cresol-formaldehyde-latex (CFL) was obtained by alternating resorcinol with low-toxicity cresol...
Abstract Antioxidants are customarily used in elastomer compounds to enhance the service life of vulcanizates enduring high temperatures, but proper selection and dosage antioxidant is critical obtain maximum beneficial effect. In this study, effectiveness several commercially available antioxidants on performance a resin‐cured bromobutyl rubber ( BIIR ) vulcanizate was investigated. The investigated belonged different chemical classes such as p‐phenylene diamine (antioxidant 4010 NA ),...
Abstract Graphene/carbon nanotubes and silica hybrids (CTGS) with high dispersion strong interface were prepared by hydrogen bond self‐assembly technique using green modifiers Tween‐80 (TW) Oleylamine (YA) as “molecular bridge.” CTGS was added into natural rubber (NR) an effective functional filler to prepare high‐performance, low‐rolling resistance, antistatic tire tread. In the vulcanization process of NR filled (CTGS/NR), can participate in vulcanization, co‐vulcanization is a catalyst...
The so called "direct powder molding" is a compressions molding process which can be directly applied to ground rubber tire (GRT). This study shows that the GRT re-used produce medium-size parts with good mechanical properties without any addition of virgin rubber. For sheets prepared from mechanically (MGRT) and cryogenically (CGRT), densities crosslink increased decrease particle size waste powder. tensile strength decreasing for two types 250 μm 120 μm, respectively, then became level....
Reclaimed rubber should be considered a source of new material with an economic impact, so the recycling waste is especially important. In this paper, sulfur-cured tire powder successfully devulcanized in normal-pressure continuous regeneration system under application activator and aromatic oil. Then, reclaimed was subjected to further mechanical shearing using two-roll mill, extruder, strainer. The effects storage time at room temperature on properties structure were examined by sol...
Effect of silica on dynamic properties styrene-butadiene/butadiene rubber (SSBR/BR) solution blends was characterized by a Rubber Processing Analyzer (RPA2000). It found that the type and loading strongly influenced mechanical in both uncured cured SSBR/BR. There synergistic effect between vulcanization reinforcement which crosslinking chains vulcanizates amplified restricting breaking network formed particles through bridges helping reformation broken network. The higher Brunauer, Emmett,...
A major goal of energy research is to use visible light cleave water directly, without an applied voltage, into hydrogen and oxygen. Since the initial reports ultraviolet (UV) activity TiO2 SrTiO3 in 1970s, researchers have pursued a fundamental understanding mechanistic molecular-level phenomena involved photo-catalysis. Although it requires UV light, after four decades still gold standard for splitting water. It chemically stable catalyzes both oxygen reactions bias. While ultrahigh vacuum...
