    • 摘要: 酪素作为一种天然产物蛋白质,既可以溶于酸也可以溶于碱.酪素溶解在氨水中所形成的膜不易溶于水,酪素和硼砂形成的溶液耐贮存且具有抗腐败的作用,因此,在实际操作中通常采用硼砂和氨水来溶解酪素.然而,单纯溶解酪素已不能满足现代工业的需求,为更好地应用于现代工业领域,需要对酪素进行一定程度的功能化改性.一般情况下,相比于未改性的酪素,改性酪素具有以下优点:(1)耐水性能更高;(2)成膜柔韧性更高;(3)耐微生物稳定性更高;(4)具有自清洁性、抗紫外性能和药物缓释等特殊性能.初期,多数研究者们通过引入聚合物单体来对酪素进行改性,以期提高酪素的耐水性或成膜性能.但随着科技的发展,人们对功能化产品的需求日益增大.为了赋予酪素特殊的功能,近几年有相关研究者采用无机纳米粒子对酪素进行改性,并采用不同的方法在酪素体系中引入不同的纳米粒子对其进行改性,使纳米粒子赋予酪素基体特殊的功能.截至目前,向酪素中引入纳米氧化锌(ZnO)、纳米二氧化钛(TiO2)和纳米四氧化三铁(Fe3 O4)等纳米粒子来改性酪素的研究已取得了初步成功,这些纳米粒子的引入可赋予酪素体系抗菌、自清洁和缓释等特殊性能.其中,采用单原位聚合法将纳米ZnO引入己内酰胺改性酪素的体系中,制得酪素基纳米ZnO复合乳液并将其应用于皮革涂饰,可赋予体系一定的抗菌性能;采用双原位聚合法将纳米TiO2引入聚丙烯酸酯改性酪素体系中,制得酪素基纳米TiO2复合乳液并将其应用于皮革涂饰,可赋予体系自清洁性能;通过设计微胶囊结构,将纳米Fe3 O4包覆在酪素胶束中,在外加磁场的作用下,应用到可控药物释放领域可赋予体系缓释功能.此外,还可在酪素体系中引入氧化石墨烯(GO)或蒙脱土(MMT)等纳米材料,赋予体系不同的特殊功能,使其应用更加广泛.本文归纳了功能化改性酪素酪素基复合材料的研究进展,分别就聚合物和无机纳米粒子对酪素的改性方法进行介绍,分析了自1993年以来改性酪素产品在各个行业的应用,同时对酪素今后的发展趋势进行了展望,为研发更多适用于不同领域的高性能功能型酪素产品提供指导.

    • 摘要: Using natural product casein as the matrix and methyl acrylic acid dimethyl amino ethyl methacrylate (DMAEMA) as the functional cationic monomer,cationic casein-based emulsion with stable structure and excellent performance was synthesized by free radical polymerization.The structure and performance of emulsion were characterized by infrared spectroscopy (FT-IR) and dynamic light scattering particle size analyzer (DLS) and minimum film forming temperature tester and so on.The antibacterial property of emulsion was also investigated by colony-counting methods.The comprehensive performance of leather coating with cationic casein was also observed.Results showed that the cationic monomer had been successfully grafted onto casein chain.When the mass ratio of casein and cationic monomer was 1∶1.5,latex particles were approximately 214.2 nm in size,ζ-potential was positive,minimum film-forming temperature was 23.8 °C.The dry and wet rubbing fastness and softness of leather had been significantly improved when adding cationic casein into finishing agent.Moreover,cationic casein emulsion had higher antibiotic resistance against staphylococcus aureus than that of pure casein,of which antibacterial rate was approximately 80%.%以天然产物酪素(CA)为基材,通过自由基聚合在酪素体系中引入阳离子单体一甲基丙烯酸二甲氨基乙酯(DMAEMA),获得了结构稳定、性能优异的阳离子酪素乳液.采用红外光谱(FT-IR)和动态光散射粒度仪(DLS)和最低成膜温度测试仪等对乳液的结构和性能进行了表征,通过菌落定量计数法对阳离子酪素的抗菌性进行了考察,并对其涂饰革样的综合性能进行考察.结果显示:阳离子单体已成功接枝到酪素的链段上;当酪素与阳离子单体质量比为1∶1.5时,可获得电位为正,平均粒径为214.2 nm的乳液;阳离子酪素乳液最低成膜温度为23.8°C;采用阳离子酪素涂饰革样后,皮革的耐干湿擦性和柔软度得到了提高;并且与纯酪素相比,阳离子酪素对金黄色葡萄球菌具有良好的抗菌效果,其抑菌率约为80%.

    • 摘要: Casein-based TiO 2 hybrid emulsion for coatings with self-cleaning property has been fabricated through double in-situ emulsion polymerization using caprolactam,acrylate and nano titanium dioxide.Struc-ture,morphology of the obtained latex and its film were characterized by TEM,AFM and SEM,while the self-cleaning property was measured by ultraviolet light.In this research,stability of the hybrid emulsion is the big-gest technical challenge due to the easy hydrolysis of TBOT.So,a series of casein-based TiO 2 hybrid emulsion by TBOT were prepared.The results showed that stability of emulsion was desirable.The particles with core-shell structure have uniform distribution and the formed coatings were endowed with obvious self-cleaning prop-erty when TBOT was 2%.More importantly,formation mechanism of resultant particles and its self-cleaning property were proposed accordingly.%以酪素为基材,采用双原位法向其中引入己内酰胺、丙烯酸酯和纳米二氧化钛(TiO 2)制备了可应用于皮革涂饰的酪素基纳米 TiO 2杂化乳液。并采用TEM、AFM、SEM 以及紫外光催化分别对乳胶粒的结构、形貌和涂层自清洁特性进行了测试与表征。控制好前驱体的水解速率,获得稳定的酪素基纳米 TiO 2杂化乳液是本研究的技术挑战。实验主要考察了钛酸丁酯用量对乳液稳定性的影响。结果表明,当钛酸丁酯用量为2%时,杂化乳液稳定。涂层具有较为明显的自清洁性能。最后,探讨了酪素基纳米 TiO 2杂化乳液的乳胶粒及涂层自清洁性能的形成机理。

    • 摘要: A series of polyurethane( PU) prepolymers were synthesized using polyethylene isophorone diisocya-nate ( IPDI) , polytetramethylene ether glycol ( PTMEG1000 ) , dihydroxy methyl propionic acid ( DMPA ) and shrinkage diethylene glycol ( DEG) as raw materials. A series of casein/polyurethane ( CWPU) emulsions were prepared with the proportion of casein and polyurethane fixed and changing the content of hard segment. The influ-ences of hard segment content on the state of emulsion, the film thermal and mechanical properties were discussed. The results showed that, with the hard segment content increasing, hydrogen bond force in casein/polyurethane in-creased, CWPU emulsion particle size increasing and having wider distribution.
