利用資源豐富的木質(zhì)素制備生物可降解材料或從木質(zhì)素中獲取高價(jià)值芳香類化合物，是高效制備生物基材料和非石油路線煉制關(guān)鍵平臺(tái)化合物的重要途徑。然而，木質(zhì)素在材料領(lǐng)域應(yīng)用還存在比較顯著的界面相容性問題，在煉制平臺(tái)化合物方面存在轉(zhuǎn)化率和產(chǎn)物選擇性較低的問題，從而制約了木質(zhì)素的快速應(yīng)用。針對(duì)以上問題，我校輕工科學(xué)與工程學(xué)院（柔性電子學(xué)院）李新平教授團(tuán)隊(duì)在木質(zhì)素化學(xué)與材料方面開展了系列研究。

游翔宇副教授等利用溶劑交換法開發(fā)了一種木質(zhì)素/聚（N，N-二甲基丙烯酰胺）和海藻酸鈉/Ca2+的雙交聯(lián)網(wǎng)絡(luò)木質(zhì)素基水凝膠。得益于多層次的剛性網(wǎng)絡(luò)和能量耗散結(jié)構(gòu)，這種兼具高模量、超韌性和優(yōu)異傳感能力的木質(zhì)素基水凝膠，在極限運(yùn)動(dòng)保護(hù)和可穿戴傳感器中顯示出應(yīng)用潛力。該研究發(fā)表于國(guó)際頂級(jí)期刊Advanced Functional Materials。

王文亮副教授等提出了一種微波響應(yīng)型催化劑，并成功用于克量級(jí)木質(zhì)素解聚蒸氣的微波輔助催化重整，為從資源豐富的木質(zhì)素中規(guī)模化獲取關(guān)鍵的酚類和芳香烴類平臺(tái)化合物提供了行之有效的途徑。該研究發(fā)表于國(guó)際頂級(jí)期刊Applied Catalysis B: Environmental和Chemical Engineering Journal。

薛白亮教授等利用五/六元環(huán)碳酸酯反應(yīng)特點(diǎn)，提出了具有動(dòng)態(tài)交聯(lián)結(jié)構(gòu)的新型木質(zhì)素基非異氰酸酯聚氨酯合成路線。基于星型木質(zhì)素接枝共聚物的可控合成，利用核-核副反應(yīng)與動(dòng)態(tài)化學(xué)策略，構(gòu)建了木質(zhì)素基動(dòng)態(tài)雙網(wǎng)絡(luò)結(jié)構(gòu)，探究了其在膠黏劑和可降解塑料等領(lǐng)域的應(yīng)用。該研究發(fā)表于Polymer Chemistry等國(guó)際期刊。
