Vitrimers are covalent polymer networks that can change their topology through thermally activated bond exchange reactions. In this work, fully biobased and recyclable vitrimers were developed from epoxidized soybean oil (ESO) natural glycyrrhizic acid (GL) as it was without additional chemical modification, which avoided the use of nonrenewable petroleum resources resolved disposal problems materials. Because unique rigid skeleton GL, ESO/GL showed good thermal stability mechanical...
Recyclable carbon fiber composites were prepared using full biobased dynamic matrices from camphoric acid and epoxidized soybean oil.
Simultaneous improvement of the stress relaxation rate and <italic>T</italic><sub>g</sub> was achieved using natural glycyrrhizic acid in transesterification reaction-based epoxy vitrimers.
Epoxy vitrimer is a kind of recyclable polymer that can reconstruct their network topology through chemical bond exchange reactions, providing an innovative solution for the thermosets recycling dilemma. However, current vitrimers have not yet reached level commercial epoxy resins, especially in performance and preparation process. In this study, high-performance has been prepared using epoxy-anhydride. presence 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD) as internal catalyst, both mechanical...
Dual-dynamic itaconic acid-based vitrimers were constructed from industrial and agricultural byproducts by one-pot inverse vulcanization.
Epoxy‐amine system is a type of important matrix material for preparation carbon fiber composites. The amidation nanotubes (CNTs) has been widely developed enhancing the mechanical properties epoxy resin matrix. However, various amino‐functionalized CNTs will produce different effect in same due to diversity reactivity, compatibility, and dispersion stability. In this paper, multiwalled (MWCNTs‐NH 2 ) were prepared through surface grafting ethylenediamine diethyltoluenediamine (DETDA;...
Carbon fiber (CF)-reinforced epoxy is the most commonly used advanced composite with high performance. However, these composites usually face intractable disposal problems in their lifecycles, due to stable cross-linked network structures of epoxy. To address this dilemma, work proposes a facile yet efficient strategy for recycling carbon fibers from traditional fiber-reinforced using epoxy–anhydride systems as matrix. Diglycidyl ester aliphatic cyclo (DGEAC) and methylhexahydrophthalic...
A PVA/Cu(OAc)<sub>2</sub> thermogel with an inherent NIR photothermal response was prepared, and its applications in smart windows photoresistors were explored.
With the gradual deepening of concept sustainable development, world is transitioning from an energy economy driven by fossil fuels to one that supplied more renewable and materials. Consequently, scientists, engineers, public, government agencies have increased their focus on materials derived natural resources. Terpenoids, a category products existed in plants, microorganisms marine animals, numerous modification sites diverse functions. It can be used create materials, which able simplify...
A novel hydroxyl-terminated liquid fluoroelastomer (HTLF) was synthesized; FT-IR, GPC and 1H-NMR result show that HTLF synthesized successfully. Then cured with HDI trimer, the structure of product characterized by FT-IR. Compared traditional solid fluorine elastomer, Cured has higher char yield faster thermal decomposition rate. It ascribed to introduction ring cross-link formed in curing process. The study chemical resistant properties tensile strength film suggested provided similar...
Host–guest polymeric hydrogels often suffer from poor biocompatibility and weak mechanical strength owing to the low complexation degree between host guest polymers. In contrast reported works, here a biocompatible host–guest macro-cross-linker (HGMC) was synthesized beforehand by of poly(β-cyclodextrin) with natural glycyrrhetinic acid-derivative functionalized acrylates at two extremities. After cross-linking polyacrylamide, three were obtained, swelling ratios micropore sizes which could...
