Renewable Microspheres Constructed by Methyl Isoeugenol-Derived Copolymers

Macromolecular Chemistry and Physics (2016)

Xueyong Yong Jinyong Zhou Huanyu Zhang Yunbin Yuan Jianping Deng

Biobased polymers have gathered a lot of interest and are currently attracting ever‐increasing attention. However, polymeric microspheres especially those derived from biomasses of small molecules, have not been extensively explored yet. This contribution reports recent exciting success in designing and preparing methyl isoeugenol (MeIE)‐derived renewable microspheres. Owing to the difficulty in homopolymerizing MeIE, it undergoes precipitation copolymerization with maleic anhydride to form the anticipated copolymeric microspheres in a high yield (both cross‐linked and non‐cross‐linked). The copolymers show high heat resistance, and the microspheres can be easily functionalized by taking advantage of the highly reactive anhydride groups. A novel type of cation exchange microspheres is further prepared by transforming the anhydride groups into carboxyl groups through hydrolyzation. The hydrolyzed microspheres demonstrate remarkable adsorption toward Cu 2+ (maximum, 300 mg g −1 ). Accordingly, the microspheres may find practical applications, e.g., as green adsorbents. The established preparing methodology can also be taken for other bio‐phenylpropenes. image

Biomass‐Derived Acetylenic Polymer Monoliths Prepared by High Internal Phase Emulsion Template Method and Used for Adsorbing Cationic Pollutants

Macromolecular Chemistry and Physics (2021)

Shenghua Yang Xueyong Yong Biao Zhao Youping Wu Jianping Deng

Abstract A new type of biobased porous polymer monolith is prepared starting from biomass, ferulic acid (FA), via high internal phase emulsion (HIPE) template polymerization method. FA is transferred into an acetylenic monomer, which undergoes catalytic HIPE polymerization, eventually forming a porous monolith named as PolyHIPE. The phenolic hydroxyl groups in the monolith are functionalized with sodium hydroxide, forming PolyHIPE‐Na + and meanwhile transforming the initial hydrophobic monolith into a hydrophilic one. The formation and structure of the monoliths are characterized with Fourier transform infrared (FT‐IR), NMR, and scanning electron microscope (SEM) techniques. The adsorption capacity of the monoliths is further investigated. PolyHIPE‐Na + exhibits high adsorption capacity toward methylene blue (MB) and cetyltrimethylammonium bromide (CTAB) from simulated wastewater. The adsorption behavior of PolyHIPE‐Na + is found to fit the pseudo second order kinetic model better. The adsorption isotherm can be well described by the Langmuir isotherm model. The maximum adsorption capacity for MB and CTAB are 1016 and 1390 mg g −1 , respectively. The biobased FA derived monolithic adsorbent also shows desirable recycling usability and stability in adsorption−desorption cycles.

Poly(N,N-dimethylacrylamide-octadecyl acrylate)-clay hydrogels with high mechanical properties and shape memory ability

RSC Advances (2018)

Feng Wang Xueyong Yong Jianping Deng Youping Wu

As a type of important intelligent materials, shape memory hydrogels (SMHs) have gathered a lot of interest due to their promising applications. However, preparing SMHs with excellent mechanical properties still remains a big challenge. In this study, a new type of SMHs with excellent mechanical strength is created. The SMHs were prepared by free radical micellar polymerization of hydrophobic monomer (octadecyl acrylate) with gelatin as emulsifier in a aqueous system containing hydrophilic monomer (N,N-dimethylacrylamide, DMA) and clay as reinforcing filler. The polymerization provided physically cross-linked network structures constructed by two non-covalent interactions, i.e. hydrophobic association formed by monomer units and multiple H-bonds among inorganic clay, gelatin and DMA. A judicious combination of the two physically cross-linked networks significantly improved the mechanical strength of hydrogels. More interestingly, the hydrogels demonstrated shape memory behavior due to the hydrophobic poly(octadecyl acrylate) domains. The novel SMHs are expected to find practical applications as biomaterials.

Biobased Microspheres Consisting of Poly(trans-anethole-co-maleic anhydride) Prepared by Precipitation Polymerization and Adsorption Performance

ACS Sustainable Chemistry & Engineering (2016)

Yunbin Yuan Xueyong Yong Huanyu Zhang Jianping Deng

This paper reports the first biobased microspheres derived from phenylpropenic resources. To explore the potentials of biomass derived trans-anethole (ANE) and to develop new biobased polymeric materials, ANE was used for preparing an unprecedented kind of polymeric microspheres constructed by poly(trans-ANE-co-maleic anhydride) [poly(ANE-co-MAH)] through free radical precipitation polymerization in methyl ethyl ketone/n-heptane mixed solvent with 2,2′-azobis(isobutyronitrile) as the initiator. Microspheres (about 1 μm in size) with spherical morphology and narrow size distribution were obtained under appropriate conditions. Following the same preparative strategy, cross-linked microspheres were further prepared with divinylbenzene as a cross-linking agent and then subjected to hydrolyzation of the surface anhydride groups into carboxyl groups, aiming at developing microsphere adsorbents. The hydrolyzed microspheres exhibited considerable adsorption ability toward trivalent chromic ion [Cr(III)] and an organic dye (methyl red), with maximum adsorption quantity of 10.8 and 17.6 mg/g, respectively. The established preparative strategy can be potentially extended to other renewable phenylpropenes and MAH derivatives, and also can be taken as a versatile platform for fabricating biobased polymeric microspheres. Apart from being potentially used as adsorbents toward diverse adsorbates (metal ions, organic compounds, etc.), the microspheres also can be further explored as biomaterials, emulsifiers, among others.

Biomass trans-Anethole-Based Hollow Polymer Particles: Preparation and Application as Sustainable Absorbent

ACS Sustainable Chemistry & Engineering (2017)

Saleem Raza Xueyong Yong Bowen Yang Riwei Xu Jianping Deng

A novel type of hollow polymer particles containing carboxyl groups was prepared from a widely available biophenylpropene trans-anethole (ANE). To prepare the hollow particles, we first prepared polymeric particles using vinyl acetate and maleic anhydride (MAH), and then such particles were taken as sacrificial templates for the subsequent formation of core/shell particles, which were synthesized by using ANE and MAH as comonomers and divinylbenzene (DVB) as cross-linking agent through precipitation polymerization. After removing the core in the prepared core/shell particles, we obtained hollow particles and then hydrolyzed the anhydride groups into carboxyl functional groups. The hollow particles were characterized by FT-IR, SEM, and TEM, and further used as absorbents. The maximum adsorption toward Cu2+ and methylene blue reached 270 and 940 mg/g, respectively. The recycling study showed that the biobased hollow particles can be easily restored and reused. The hollow particles may find practical applications as sustainable absorbents. The established methodology for preparing hollow polymer particles is expected to be applicable for other biophenylpropenes.
