In this study, a series of biobased polyols were prepared from olive, canola, grape seed, linseed, and castor oil using novel, solvent/catalyst-free synthetic method. The triglyceride oils first oxidized into epoxidized vegetable with formic acid hydrogen peroxide, followed by ring-opening reaction fatty acid. molecular structures the resulting polyurethane characterized. effects cross-linking density on thermal, mechanical, shape memory properties polyurethanes also investigated.
Abstract Materials with multifunctionality or multiresponsiveness, especially polymers derived from green, renewable precursors, have recently attracted significant attention resulting their technological impact. Nowadays, vegetable‐oil‐based waterborne polyurethanes (WPUs) are widely used in various fields, while strategies for simultaneous realization of self‐healing, reprocessing, shape memory as well high mechanical properties still highly anticipated. We report development a...
Biopolymer/silica nanocomposite aerogels are highly attractive as thermally insulating materials for prevailing energy-saving engineering but usually plagued by their lack of mechanical strength and environmental stability. Lignin is an appealing plant phenolic biopolymer due to its natural abundance, high stiffness, water repellency, thermostability. However, integrating lignin silica into high-performance 3D hybrid remains a substantial challenge the unstable co-sol process. In diatoms,...
Bio-based polyols from epoxidized soybean oil and castor fatty acid were developed using an environmentally friendly, solvent-free/catalyst-free method. The effects of the molar ratios carboxyl to epoxy groups, reaction time, temperature on polyols’ structures systematically studied. Subsequently, polyurethane films prepared these green polyols. Properties new, soy-castor based compared with two other methoxylated polyol, respectively. Thermal mechanical tests showed that new exhibited...
The Hansen solubility parameters of a soy-castor oil-based polyol and petroleum-based are investigated to evaluate their miscibility for polyurethane blends. two polyols were found be miscible at different ratios over temperature range from 25 90 °C. Blends with these used prepare foams. With increasing levels bio-based content, the density open cell foams increased. thermal stability improved, conductivity increased, bio-content, while foam's compression strength decreased. This study...
A solvent-free and scalable method was developed for the preparation of soybean-oil-based polyols by a thiol–ene photo-click reaction with homemade photochemical reactor. The effect parameters, including photoinitiators, time, molar ratios thiols to carbon–carbon double bonds, power mercury lamp, on structures resulting investigated. mechanism also discussed. On basis these novel polyols, several polyurethanes were prepared using different diisocyanates (aliphatic, cycloaliphatic, aromatic...

In this article, a kind of degradable composite was prepared from bamboo fiber (BF), poly lactic acid (PLA), and polypropylene (PP). The mechanical thermal properties were characterized by the universal testing machine, thermogravimetric analysis, differential scanning calorimetry. order to improve compability between BF polymer matrix several modification on surface explored compared. Moreover, compatibilizer (maleated PP) applied further increase compatibility matrix. It is found that...
Vegetable oil-based polymeric materials always suffer from relatively poor performance, such as lower tensile strength and glass transition temperatures, than petroleum-based materials, which greatly limit their practical applications. In this study, octahydro-2,5-pentalenediol (OPD) was synthesized naturally occurring citric acid used together with castor oil the polyol blends for production of bio-based waterborne polyurethane (PU) dispersions (PUDs). The effects OPD contents on particle...
Novel bio-based epoxy resins with high tensile strength, rapid self-healing and excellent multiple recyclability were synthesized through thiol–epoxy “click” reaction between epoxidized vegetable oils dithiol-functionalized boronic ester.
The deposition of pesticides and their retention on plant surfaces are critical challenges for modern precision agriculture, which directly affect phytosanitary treatment, bioavailability, efficacy, the loss pesticides. Herein, a novel eco-friendly waterborne polyurethane delivery system was developed to enhance spray pesticide surfaces. More specifically, biobased cationic anionic dispersions were synthesized from castor oil. Both exhibited remarkable microstructural, amphiphilic,...
