采用半连续单体乳液滴加法聚合法,以石蜡(PF)为种子、丙烯酸(AA)为壳,制备石蜡/丙烯酸(PFAA)核壳聚合乳液。以乳液特性粘数([η])为评价指标,利用正交实验L9(34)筛选最佳工艺条件。考察了反应温度θ、反应时间t、引发剂K2S2O8用量和单体AA用量对PFAA乳液[η]的影响。结果表明,影响乳液[η]因素的大小顺序为θ>t>w(K2S2O8)>w(AA),较优的工艺条件:θ=70～75℃,t=2h,w(K2S2O8)=0.16%～0.20%,w(AA)=16.5%～18.0%。     

Transparent antifouling coatings via nanoencapsulation of a biocide

Transparent coatings releasing an antifouling agent (AF) can be used to reduce the marine fouling of optical lenses. A variety of water‐borne coatings based on poly(methyl methacrylate‐co‐butyl acrylate) (PMMA‐co‐PBA) were synthesized using a two‐stage miniemulsion process. During this process, the AF, SeaNine 211, was nanoencapsulated in domains small enough not to scatter light. The release rate of SeaNine 211 was studied for the polymers of different T_g, and found to be sufficient to impart AF properties. However, over time, the coatings were found to develop a whitish aspect (blushing) due to water retrodiffusion. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci, 2007

Simulation of oil spills near environmentally sensitive areas in Egyptian coastal waters

Oil spills in Egyptian coastal waters have a direct impact on the national economy because of the potential environmental damage, and the corresponding negative effect on tourism. Computer simulations of oil spills were performed for four environmentally sensitive areas along Egyptian coasts using an existing oil spill model that incorporates the important variables and processes affecting oil transport in seawater. The expected slick trajectory and variation of oil properties with time were calculated for a proposed spill scenario at each site. Water current maps, the most critical model input parameter with respect to spill trajectory, were developed for each location. The simulations demonstrated that the most important oil property affecting spill response decisions and operations is the emulsion viscosity, in that it indicates when, where, and how responders can intervene for cleanup.
