“…Summarizing T g and T di values of fully and partially biobased SMPs reported in literature so far (Figure b, Table S1), − ,,− it is interesting to conclude that poly(IE-dea) and poly(G-dea) have superiorly high, and in fact the highest, thermal resistance among all available fully biobased SMPs reported so far.…”

“…Reviewing available SMPs based on neat benzoxazine resins, none of them is fully biobased. Researchers prepared a fully biobased SMP by copolymerizing benzoxazine and epoxy resin . In order to endow a polymer with shape memory capability, the polymer usually should have two specific structural features: One is having a reversible transition phase that melts or softens at the temperature above T g , which allows the polymer to form a temporary structure under external stress conditions; the other is having fixed points that are stable at the temperature above T g .…”

Developing high-performance fully biobased shape memory thermosets with a green strategy is a challenging topic of great interest. Herein, two unique fully biobased benzoxazine resins with excellent shape memory properties, denoted as poly(IE-dea) and poly(G-dea), were developed by synthesizing two fully biobased benzoxazine monomers (IE-dea and G-dea) using a solvent-free method. The thermal, mechanical, and shape memory properties of poly(IE-dea) and poly(G-dea) were studied. Among the fully biobased shape memory polymers reported so far, poly(IE-dea) and poly(G-dea) have the highest glass transition temperatures (138 and 216 °C), initial thermal decomposition temperatures (340 and 347 °C), and tensile strengths (85.1 ± 2.5 and 65.9 ± 2.7 MPa). In addition, poly(IE-dea) and poly(G-dea) exhibit excellent shape memory properties. After four shape memory cycles, their shape fixity ratios are 97.7–98.0% and 96.7–97.2%, respectively, and their shape recovery ratios are 96.7–97.2% and 93.0–93.4%. In fact, they are the first two fully neat biobased shape memory benzoxazine resins up-to-date. The mechanism behind the excellent integrated performances of poly(IE-dea) and poly(G-dea) results from unique integrated actions of the flexible decane segment and rigid cross-linked structure from the polymerization of oxazine rings.

“…Due to the cross‐linking reaction involving double bonds in isoeugenol‐based benzoxazine, at the same time, the integration of flexible long chains and rigid groups also endows the resins with shape memory property 165 . Combined with the Schiff base reaction between aldehyde group and polyether amine 166 or copolymerization with epoxidized vegetable oil, 167 vanillin‐based shape memory resins were developed as well. Moreover, with the assistant of Schiff base reaction, Ishida et al 168 designed a bio‐resourced benzoxazine with long chain ethers, which was successfully applied in surfactant agent.…”

Due to the rapid depletion of crude oil and serious environmental pollution, the synthesis of polymers from renewable resource is becoming more and more important. Up to now, a great variety of biomass and bio-based platform compounds have been taken to prepare the polymers. However, as two representative thermosetting resins, epoxy and benzoxazine resin derived from renewable feedstocks only obtain limited attention compared with the popular bio-based plastics, including PLA, PBAT and PHBV etc. The reason might be that the properties of previously reported thermosetting resins directly obtained from biomass are usually unsatisfied, and their application fields are limited. In this paper, the latest development on the synthesis of highperformance bio-based epoxy and polybenzoxazine resins are reviewed. In addition, to further broaden their applications, the functionalization strategies are also summarized. The objective of this work is to help us fully aware the present situation of bio-based thermosetting resins and then promote their faster development, especially practical application.

“…Shape memory behaviours of this copolymer could be triggered by NIR without using any light-thermal fillers. 64 The mechanism was that light-thermal effect of π–π interactions among polymer chains provided the energy for shape recovery and glass transition of the copolymer.…”
