【摘要】：以3,6-二甲基-2,5-吡嗪二羧酸(P)和三聚氰胺(M)為組分,采用不同的摩爾比(1∶1,1∶2,1∶3)混合配制了3個(gè)樣品PM11,PM12和PM13,并對(duì)其凝膠性能進(jìn)行了測(cè)試.實(shí)驗(yàn)結(jié)果表明,PM能在水中及部分含水有機(jī)溶劑中形成穩(wěn)定的凝膠,這些凝膠對(duì)酸堿具有良好的響應(yīng)性能.采用掃描電子顯微鏡分析了3種水凝膠的微觀形貌,均為纖維狀的網(wǎng)絡(luò)結(jié)構(gòu);紅外光譜及紫外光譜測(cè)試結(jié)果表明氫鍵是形成凝膠的關(guān)鍵驅(qū)動(dòng)力;XRD測(cè)試結(jié)果顯示凝膠為層狀結(jié)構(gòu).對(duì)PM12在不同pH值的水中的凝膠性能測(cè)試結(jié)果表明,在pH=3~11的范圍內(nèi)PM12均能形成凝膠.測(cè)試了PM12在混合溶劑中的凝膠性能,并將測(cè)試結(jié)果與混合溶劑的Hansen溶解度參數(shù)關(guān)聯(lián),以便用于分析溶劑與凝膠因子間的相互作用,所得結(jié)果亦表明氫鍵在凝膠形成的過(guò)程中起重要作用.
[Abstract]:Three samples of PM11,PM12 and PM13, were prepared and their gel properties were tested by using different molar ratio (1: 1: 1: 1: 2: 1: 3) of (P) and melamine (M), which were composed of 3 dimethyl-6-dimethyl-5-pyrazine dicarboxylic acid (P) and melamine (M). The experimental results show that PM can form stable gels in water and some aqueous organic solvents, and these gels have good response to acid and alkali. Scanning electron microscopy (SEM) was used to analyze the microstructure of the three hydrogels, all of which were fibrous network structure, and the results of IR and UV spectra showed that hydrogen bond was the key driving force to form the gel. The XRD results showed that the gel was layered. The gel properties of PM12 in water with different pH values showed that the gel could be formed by PM12 in the range of pH=3~11. The gel properties of PM12 in mixed solvents were tested, and the results were correlated with the solubility parameters of Hansen for the purpose of analyzing the interaction between solvent and gel factor. The results also show that hydrogen bond plays an important role in the formation of gel.
