以丙烯酸丁酯、苯乙烯、甲基丙烯酸异冰片酯、甲基丙烯酸甲酯、甲基丙烯酸羟乙酯和甲基丙烯酸十二氟庚酯为原料,以二甲苯、乙酸丁酷、丙二醇甲醚醋酸酯为混合溶剂,AIBN为引发剂,通过聚合反应获得了含氟聚丙烯酸酯FPA,详细探讨了反应釜的反应温度、反应时间、单体滴加速度、引发剂用量、甲基丙烯酸十二氟庚酯用量及加料方式、甲基丙烯酸羟乙酯用量等工艺参数对FPA性能的影响,优化了合成工艺。

Withbutyl acrylate, styrene, methacrylic acid isoborneol ester, methylmethacrylate, hydroxyethyl methacrylate and methacrylic acid perfluoro heptylester as raw material, xylene, butyl acetate cool, propylene glycol monomethylether acetate as solvents and AIBN as initiator, polymerization by won thefluorinated polyacrylate FPA, a detailed discussion of the reactiontemperature, reaction time, monomer dropping speed, triggered the effect ofprocess parameters on the performance of the FPA agent, methyl acrylic twelvefluorine heptanoic acid dosage and way of feeding, methyl hydroxy ethylacrylate dosage, the synthetic process was optimized.

利用异佛尔酮二异氰酸酯和直链两端型聚醚改性硅油(SF-739)的加成反应,通过调节反应温度、单体滴加速度、SF-739分子量等参数实现了有机硅改性的聚氨酯SPU的性能优化。利用自制的FPASPU固化获得了初步的涂层材料,研究了二者物料配比对涂层性能的影响。

Additionreaction using isophorone diisocyanate and straight chain ends type polyethermodified silicone oil SF-739, by reaction temperature, regulating monomerdroplet acceleration, molecular SF-739 amount of parameters achieve thesilicone modified polyurethane SPU performance optimization. The preliminarycoating materials were obtained by FPA and SPU, and the effect of materialratio on the properties of the coating was studied in the two party.

以环(脯氨酸-丙氨酸)、辣椒素、1,2-苯并异噻唑啉-3-酮及碱性蛋白酶、葡聚糖酶、溶菌酶、辣根过氧化物酶共7种不同类型的防污剂,通过硅藻附着实验、藤壶幼虫溶液存活实验,探讨了环(脯氨酸-丙氨酸)、辣椒素、1,2-苯并异噻唑啉-3-3反应釜防污剂的硅藻半抑制浓度和藤壶幼虫半致死浓度。利用壳聚糖为缓释载体材料、液体石蜡为分散剂、戊二醛为交联剂可实现1,2-苯并异噻唑啉-3-酮或辣椒素的微球化包埋,利用FTIRSEMXRDTG/DTA等技术手段研究了微球的理化性能,并通过体外释放实验,探索了其控释规律。

Toring (proline alanine), capsaicin, vinyl benzene and isothiazole oxazoline4-ene-3-one and alkaline protease, glucanase, lysozyme, horseradish peroxidase,a total of seven kinds of different types of antifouling agent, by diatomattachment experiment, barnacle larvae solution survival experiment, analyzedthe (prolyl alanine), capsaicin, vinyl benzene and isothiazole quinoline4-ene-3-one three antifouling agent diatom half inhibitory concentration andbarnacle larvae semi lethal concentration. Using chitosan as the sustainedrelease carrier material and liquid paraffin as dispersant, glutaraldehyde ascrosslinking agent can achieve 1,2 benzene and isothiazole oxazoline 4-ene-3-oneor capsaicin microsphere embedding, by means of FTIR, SEM, XRD, TG / DTAtechnique to study the physicochemical properties of microspheres, and the invitro release experiment and explore its controlled release rules.

在不同模板剂存在的条件下,以TEOS为硅源水热合成获得了2种介孔材料SBA-15MCM-41,先以APTESAAPTS实现了二者的氨基化改性,以丁二酸酐实现了二者的羧基化改性;并利用改性前后的10种介孔材料为载体实现了碱性蛋白酶、葡聚糖酶、溶菌酶及辣根过氧化物酶的有效负载,探索了不同载体材料对4种酶类防污剂的固定化效果以及固定化酶的热稳定性、pH稳定性及操作稳定性性能的影响。(3)设计并构建了低表面能型、微结构型、防污剂释放型、酶类负载型、硅油渗出型等共520种仿生防污涂层,研究了涂层的基本理化性能。

Underthe conditions of different templates exist, with TEOS as silica source,thermal synthesis the two dielectric mesoporous materials SBA-15 and MCM-41,first by APTES or aapts realized two amino modified, with succinic anhydride toachieve the two carboxyl modified; and the change before and after the 10 kindsof mesoporous materials material(www.gfanyingfu.com/) as the carrier to achieve the alkalineprotease, glucanase, lysozyme and horseradish peroxidase payload, and explorethe different carrier material of the four enzymes antifouling agent fixedeffect and effect on the thermal stability of the immobilized enzyme, pHstability and operation stability. (3) design and construction of the type,micro structures, antifouling agent release type, enzyme load type, siliconeoil exudative and other five kinds of 20 kinds of biomimetic antifoulingcoatings with low surface energy, the basic physical and chemical properties ofthe coating were studied.
