Vitrimers are a new type of polymers with promising applications in innovative materials. Epoxidized soybean oil (ESO) is an ideal candidate for vitrimer preparation owing to its abundant epoxy groups. However, preparing plant oil-based vitrimers high glass transition temperatures (Tg) and strength remains challenging. A novel fully bio-based Tg above room temperature was synthesized from ESO rosin derivative-fumaropimaric acid (FPA) exhibited excellent self-healing, shape memory,...
This work introduces dual dynamic covalent bonds in the network of a non-isocyanate polyurethane prepared using cyclic carbonate derived from CO 2 to realize self-healing and reprocessing at low temperature (50 °C) or under UV light.
The objective of this study was to investigate the silica-silane bond formation present at filler interface dental composites. Diffuse reflectance infrared Fourier transform spectroscopy used, and spectra pyrogenic silica (Cab-O-Sil) treated with different concentrations γ-methacryloxypropyltrimethoxy-silane (MPS) were analyzed. outcome suggested that γ-methacryloxypropyltrimethoxysilane molecules oriented parallel colloidal surface formed two types bonds. One these bonds a siloxane bridge...
Developing bionanocomposites from renewable biomass is a viable supplement for materials produced mineral and fossil fuel resources. In this study, nanocomposites composed of carboxylated cellulose nanocrystals (CCNs) silver nanoparticles (AgNPs) were prepared used as bifunctional nanofillers to improve the mechanical antimicrobial properties waterborne polyurethane (WPU). Morphology, structure performance CCNs/AgNPs WPU-based films investigated. composite homogeneous reinforced. The...
Rosin modified aminopropyltriethoxysilane (RA) was prepared via an epoxide ring opening reaction of rosin based glycidyl ester with aminopropyltriethoxysilane. The structure RA confirmed by Fourier transform infrared spectroscopy (FT-IR), 1H NMR, and 13C NMR. used as a cross-linking agent to prepare room temperature vulcanized (RTV) silicone rubber hydroxy terminated polydimethylsiloxane (PDMS) matrix in the presence organotin catalyst. Morphological, thermal, mechanical properties RTV...
We report on an efficient method for the formation of modified cellulose-based materials with enhanced hydrophobic properties, formed by grafting polymeric epoxidized soybean oil (ESO) as a renewable, environmentally friendly, and low cost raw material. The process occurred via ring-opening polymerization, wherein cellulose hydroxyl groups acted initiators in presence SnCl4 catalyst, linking fibers ESO ether linkages, thereby forming matrix. surface polarity was therefore decreased...
Rigid polyurethane foam (RPUF) is one of the most widely used construction materials, but it flammable and releases toxic smoke during combustion. In this study, a novel, synergistic-effect flame retardant (FPASO-DOPO) was synthesized by Atherton–Todd reaction 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) with fumaropimaric acid-based siloxane (FPASO). The obtained FPASO-DOPO then introduced into cross-linking network an RPUF chemical bonding. retardancy enhanced synergistic...
With the development of high-frequency communication, miniaturization integrated circuits (ICs) has led to interconnected signal delays and losses. The dielectric properties epoxy resins are no longer satisfactory, because presence polar groups. Herein, a benzocyclobutene-rosin modifier was designed synthesized reduce constant resins. recross-linking network benzocyclobutene inhibits polarizability groups, rosin skeletons increase free volume Consequently, decreased from 3.12 2.72 their...
To investigate the potential application value of dehydroabietic acid, 27 novel dehydroabietyl-1,2,4-triazole-5-thioether-based derivatives were designed and characterized by IR,
Acrylpimaric acid-modified aminopropyltriethoxysilane (APA-APTES) was prepared and confirmed by FT-IR, 1H NMR, 13C NMR. The APA-APTES used as a cross-linking agent in the preparation of modified room-temperature-vulcanized (RTV) silicone rubber. effects on thermal stability mechanical properties rubber were investigated. APA-APTES-modified RTV rubbers have significantly improved compared with unmodified Such are due to presence hydrogenated phenanthrene ring APA-APTES, which induces network...
CO<sub>2</sub> was fixed by synthesizing a cyclic carbonate, which used to prepare non-isocyanate polyurethane that can be reprocessed.
Two series of dehydroabietyl-1,2,4-triazole-4-Schiff-based derivatives were synthesized from rosin to control plant fungal diseases. In vitro evaluation and screening the antifungal activity performed using Valsa mali, Colletotrichum orbiculare, Fusarium graminearum, Sclerotinia sclerotiorum, Gaeumannomyces graminis. Compound 3f showed excellent fungicidal against V. mali (EC50 = 0.537 μg/mL), which was significantly more effective than positive fluconazole 4.707 μg/mL). also had a...
To develop new antioomycete agents against plant pathogens, two series of acrylopimaric acid triazole derivatives from rosin were synthesized. The in vitro activity these was evaluated and screened Pseudoperonospora cubensisi, Plasmopara viticola, Phytophthora sojae, infestans, capsici. Compound 5m showed the highest P. capsici, with a half-maximal effective concentration (EC50) value that lower than positive control metalaxyl (1.391 1.815 mg/L, respectively). demonstrated satisfactory...
Thermosetting foams have limited capabilities for recycling, reprocessing, or reshaping. Moreover, most of the foaming agents currently employed in these are derived from organic compounds sourced petrochemicals, thereby posing a significant environmental threat due to heightened pollution. To solve problems, fully biobased degradable vitrimer foam (EPC-X) was fabricated using an environmentally friendly all-in-one strategy by cross-linking epoxidized malepimaric anhydride (EMPA),...
