1单分散多孔聚MMA/HEMA微球的制备显示文摘采用液滴微流控法,制备了单分散性良好的水包油(O/W)乳液,以此乳液为模板,通过紫外光引发聚合得到单分散多孔聚甲基丙烯酸甲酯(MMA)/甲基丙烯酸2-羟乙酯(HEMA)多孔微球。研究了油相中表面活性剂聚蓖麻酸甘油酯(PGPR)含量对微球表观密度孔隙率及对乙二醇二甲基丙烯酸酯(EGDMA)的吸附能力的影响。结果表明:增加PGPR含量可改变微球的多孔结构并增大其吸附能力,在油污废水处理领域具有潜在的应用价值。曹雪入 余亚兰 王舰苇 蒋阿丽 2020应用化工2020,49,4:2
2Preparation and evaluation of nano-hydroxyapatite/poly(styrene-divinylbenzene) porous microsphere for aspirin carrier显示文摘A novel vehicle for the delivery of aspirin (ASA) was prepared from porous nano-hydroxyapatite/poly(styrene-divinylbenzene) [nano-HAP/P(St-DVB)] composite microspheres by grafting nano-HAP [Ca10(PO4)6(OH)2] onto porous P(St-DVB) microspheres. Four types of porous composite microspheres were prepared, each with different nano-HAP contents. The ASA-loaded composite microspheres prepared with 10% and 15% nano-HAP (mass ratio) exhibited excellent buoyancy with relatively short instantaneous floating time (within 10 min) and a long sustained floating time (12 h) in simulated gastric juice. They also offered good sustained release of ASA (up to 8 h). Furthermore, these composite microspheres displayed good buffering capacity that prevented the buildup of acidity caused by hydrolysis of ASA, keeping the pH of gastric juice within the normal range (pH 0.9 to 1.5). The results showed that porous nano-HAP/P(St-DVB) composite microspheres prepared with 10% and 15% nano-HAP could be used as a novel drug carrier for ASA, providing a sustained release dose without leading to stomach irritation, a side effect that is often associated with ASA medication.LI Sen WANG Kuan CHANG Kue-Chieh Alan ZONG Ming WANG Jing CAO YongGang BAI YuHua WEI TaiMing ZHANG ZhiRen 2012Science China Chemistry2012,55,6:1
3γ-聚谷氨酸防晒纳米粒子的制备及性能显示文摘以天然大分子γ-聚谷氨酸(γ-PGA)为原料,使用疏水小分子L-苯丙氨酸乙酯(L-phe)对其进行改性得到双亲大分子,通过大分子自组装的方法负载阿伏苯宗(AVB)、甲氧基肉桂酸异辛酯(OMC)和二苯甲酮-3(BP-3)3种有机防晒剂得到γ-PGA防晒纳米粒子,并对其光稳定性、广谱防晒性、皮肤渗透性和细胞毒性进行了研究。结果表明,紫外辐照后,与未负载的有机防晒剂组合物相比,γ-PGA防晒纳米粒子在UVA范围的吸光度从12%降低至3%,在UVB范围的吸光度从18%降低至4%,光稳定性得到了提升。同时,制备的防晒纳米粒子在整个紫外波段具有广谱防晒性、低皮肤渗透性和低细胞毒性。将该防晒纳米粒子应用于防晒霜配方中,当添加量为配方总质量的10%时,防晒霜防晒指数(SPF)可达75。梁雪 孟宇寰 刘晓亚 李小杰 2022精细化工2022,39,1:1
