Description
技术领域
本发明涉及海水淡化领域，特别涉及一种用于光热转换的双面膜材料的制备方法。
背景技术
随着全球人口的快速增长和水污染问题日益严重，水资源紧缺问题正成为人类社会面临的主要危机之一。预计在2025年，全球将有三分之二的人口面临水资源匮乏问题。为解决这个问题，海水淡化技术得到了人们极大的重视，传统的海水淡化技术包括膜法和热法，工艺复杂、设备庞大、占地面积广且需要很高的能源驱动。
太阳能海水淡化技术利用光能淡化海水，是一种解决水危机问题的低碳环保的技术方案。日常条件下，海水对太阳光的吸收率很低，不能有效地将光能吸收用于海水的蒸发。界面光热转换技术由于具有更高的能量转换效率，获得了广泛的关注和深入的研究。该技术将吸收体置于汽-液界面，可只加热水体界面薄层水产生蒸汽，从而获得更高的光热-蒸汽转换效率。
目前绝大多数光热转换材料在自然光照强度下能量转换效率低、耐盐性能差、机械强度差、循环使用性差，且多数光热转换膜材料的制备还比较复杂，有些需要高真空、高温等苛刻的实验条件或者昂贵的精密加工设备，难以实现规模化制备，限制了其推广应用。同时兼具双功能的双面膜光热转换材料是深化太阳能海水淡化技术的关键。
目前有很多文献和专利都公开了双面膜光热转换材料的技术，虽然解决了一些问题，但是都存在不同的缺陷，不能满足批量海水淡化的需求：文献《Flexible and SaltResistant Janus Absorbers by Electrospinning for Stable and Efficient SolarDesalination》公开的双膜结构是光吸收物质炭黑（CB）为喷涂在材料表面，这种制备方式因CB和PMMA为静电吸附，会造成光吸收物质在长期使用过程中脱落，耐用性差；文献《Two-Dimensional Flexible Bilayer Janus Membrane for Advanced Photothermal WaterDesalination》公开的双膜结构底部碳纳米管膜由CVD方法制备，上层Au为抽滤获得，这种方式Au价格昂贵，抽滤方法所得膜的机械强度差，上下两层容易分离，Au层的Au容易脱落；文献《A Janus Evaporator with Low Tortuosity for Long-Term Solar Desalination》公开的双膜结构通过冷冻干燥的方式获得CNF/CNT气凝胶，在气凝胶的顶部涂覆二氧化硅，冷冻干燥的方式复杂，不适用于规模化生产，且获得的材料机械性能非常差；授权公开号为CN 111282443 B的专利文件公开的用于太阳能界面蒸发海水淡化的膜材料及其制备方法，光吸收物质是通过烧蚀、碳化获得，激光烧蚀的可控性较差，且这种方法制备得到材料机械强度较差。
所以开发低成本和可大规模应用的双面膜光热转换材料以实现最佳的吸光、高效热能转换和水蒸发、具有优异的耐盐性能是一项极具挑战性的工作。
发明内容
为解决现有技术存在的缺陷，开发低成本和可大规模应用的双面膜光热转换材料，本发明是提供一种用于光热转换的双面膜材料的制备方法。该种方法制备双面膜具有优异的光吸收特性，高孔隙率。在1kW/m2太阳光（俗称1个太阳光）下，该材料可以产生水汽并冷凝成水，具有优异的光热转换效果；该材料具有优异的耐盐性，光热表面没有盐分沉积；该材料可循环使用，不受待处理海水浓度和水量的影响。
本发明的技术方案是：一种用于光热转换的双面膜材料的制备方法，包括纺丝液配制、静电纺丝、疏水化处理、热压、清洗晾干过程，按以下方法配制纺丝液：将PVDF加入DMF溶剂中，在25~80℃油浴中搅拌0.5~12h，再加入碳纳米材料，在30~80℃下继续搅拌1~12h，后超声处理5~60min，得到纺丝液；

具体实施方式
一种用于光热转换的双面膜材料的制备方法，包括以下步骤：
步骤一，纺丝液配制：将PVDF加入DMF溶剂中，在25~80℃油浴中搅拌反应0.5~12h，再加入碳纳米材料，在30~80℃下继续搅拌1~12h，后超声处理5~60min，得到纺丝液；碳纳米材料选自粉状活性炭、炭黑的一种或两种以上任意比例的混合物；PVDF的质量分数为0.08~0.25g/mL，碳纳米材料的质量分数为0.02~0.25g/mL，PVDF和碳纳米材料的质量比是4:1~1:2。
步骤二，静电纺丝：采用静电纺丝技术，以亲水性材料作为基底，静电纺丝得到纳米纤维复合膜；
亲水性材料选自滤纸、聚对苯二甲酸乙二醇酯无纺布简称PET无纺布、聚氨酯泡沫中的一种；
静电纺丝的实验参数如下，施加正电压为15~20kV，施加负电压为2~10kV，针头与接收器之间的距离为8~20cm，推注速度为10~30μL/min，纺丝时间为8min~1h；
静电纺丝采用针头的型号为18~25G；
静电纺丝中的收集器为平板型收集器、转轴型收集器，转轴型收集器的转速为5~100rpm。
步骤三，疏水化处理：采用喷涂技术，使用喷枪将二氧化硅溶胶均匀地喷涂在上述步骤二制备的纳米纤维复合膜电纺膜一侧；载气选自压缩空气，高纯氮，高纯氩气中的一种，喷枪喷嘴与待喷涂表面的距离为5~30cm，从左至右以2~5cm/s的速度从上到下依次喷涂，喷涂压力为10~30psi，随后从上至下以2~5cm/s的速度从左到右依次喷涂，喷涂压力不变，如此重复两次至五次。
步骤四，热压：采用热压技术，将上述步骤三制备的纳米纤维复合膜进行热压，使得两面膜粘接更紧密；升温速度为5~15℃/min，热压的温度为常温~120℃，热压的时间为5~30min，压力为1~8MPa。
步骤五，清洗晾干：将步骤四中制备的双面膜在水中清洗去除多余溶剂，放入烘箱中干燥，干燥温度为25~50℃，干燥后得到用于光热转换的SiO2/C@PVDF/PET双面膜材料。该双面膜材料用于海水淡化、污水处理和加速晒盐，具有防雨功能，在材料用于晒盐时，可在阴雨天气阻挡雨水进入盐池。
实施例
根据权利要求限定的技术参数，表1列举了十六个实施例中每步需要调整的技术条件的具体值，未列举项按照具体实施方式的相关条件实施，表2是十六个实施例所制得的产品性能统计表。
表1：实施例中的关键技术条件统计表
续表1：实施例中的关键技术条件统计表（续）
对所得产品在一个太阳光照强度下测试水蒸发速率，当使用测试水样为3.5%NaCl溶液时，得到速率A，测试10个周期（每次2h）之后，得到速率B；当使用测试水样为20%NaCl溶液时，得到速率C，具体值详见表2。
表2：实施例中得产品效果统计表
从表2中结果可以看出，所制得的SiO2/C@PVDF/亲水基底双面膜超细纤维膜材料，在处理3.5%NaCl溶液时，水蒸发量均超过1.5kg/m2·h，工作10个周期（每次2h）后，水蒸发速率降低不超过4%。在处理高盐度水样（20%NaCl溶液）时，水蒸发速率的变化也很小，下降不超过3%，均表现出优异的光热转换性能、耐用性能和耐盐性能。
对比实施例1~16的数据可知：PVDF浓度以及碳纳米材料的种类和浓度的不同，对性能有所影响，其原因在于：PVDF浓度影响纺丝过程中纤维的形貌，PVDF浓度过低时，受力拉伸不均匀，产生串珠结构纤维，浓度过高时，纤维直径增大，比表面积降低，并且超过浓度最大范围时将无法得到连续的纤维；碳纳米材料的种类和浓度影响膜的吸光性能，当碳纳米材料含量过低时，吸光度降低，碳纳米材料含量过高，和PVDF混合困难，并且在纺丝过程中会堵塞针头。活性炭与炭黑因为不同的结构性能，与PVDF混合时，会影响纺丝液的粘度，在纺丝液浓度相同时，添加活性炭的性能要更好。
对比实施例7~9的数据可知，亲水基底影响膜性能，具体体现在：不同的基底（1）影响膜的强度，（2）影响膜的亲水性，（3）影响与上层电纺膜的相互作用。
对比实施例7~13的数据可知，静电纺丝的电压和推注速度是一个重要的工艺参数，（1）电压：当所加电压不同时，针头顶端的液滴会产生不同的形状，从而影响所产生的喷射液滴及细流尺寸的分布情况、纤维状态。（2）推注速度：当推注速度过小时，难以形成连续的纤维，当推注速度过大时，喷射的细流来不及干燥就落在收集器上，容易造成纤维缺陷。
对比实施例1~16数据可知，喷丝针头与收集器之间的间隔与纺丝时间是一个重要的工艺参数，喷丝距离增大，喷射区域增大，单位时间内电纺膜的厚度降低，纺丝时间增加，电纺膜厚度增加。
对比实施例13~16数据可知，疏水化处理过程中，距离影响SiO2的喷涂量，喷涂量过低，表面疏水化程度不足，造成盐粒子在表面析出，喷涂量过高，影响水蒸发速率。
由表2《所得产品效果统计表》可以看出，在十六个实施例中，实施例7所制备的SiO2/C@PVDF/PET双面膜性能优异，该膜孔隙率高，均一性好，如图1所示；该膜具有较强的光吸收率，测试其在太阳光谱250nm～2500nm的光吸收率大于98%，如图2所示；测试其接触角为158°，具有超疏水性，具有防雨功能，如图3所示；对其蒸发速度进行测试，在一个太阳光下其蒸发速率高达1.68kg/m2·h，光热转换效率为94.5%，如图4所示；当在1个光照强度下，实时测试材料表面的温度，当太阳光照射材料表面后，温度迅速升高，并在400s达到53℃，并保持稳定，表现出优异的光热转换性能，如图5所示；对膜表面进行10个周期（每次2h）光照，其蒸发速率保持稳定，表面结构没有被破环，具有极强的耐久性和稳定性，如图6所示。综上所述，实施例7是本发明最佳实施方式，技术方案为：
步骤一，纺丝液配制：将15gPVDF和加入100mL的DMF溶剂中，在60℃油浴中搅拌反应0.5~12h，再加入9g粉状活性炭，在30~80℃下继续搅拌1~12h，后超声处理5~60min，得到纺丝液；
步骤二，静电纺丝：采用静电纺丝技术，以PET无纺布作为基底，静电纺丝得到纳米纤维复合膜；
静电纺丝的实验参数如下，施加正电压为18kV，施加负电压为2kV，针头与接收器之间的距离为15cm，推注速度为15μL/min，纺丝时间为15min；
静电纺丝采用针头的型号为20G；
静电纺丝中的收集器为平板型收集器、转轴型收集器，转轴型收集器的转速为5~100rpm。
步骤三，疏水化处理：采用喷涂技术，使用喷枪将二氧化硅溶胶均匀地喷涂在上述步骤二制备的纳米纤维复合膜电纺膜一侧；载气选自压缩空气，喷枪喷嘴与待喷涂表面的距离为10cm，从左至右以2~5cm/s的速度从上到下依次喷涂，喷涂压力为10~30psi，随后从上至下以2~5cm/s的速度从左到右依次喷涂，喷涂压力不变，如此重复两次至五次。
步骤四，热压：采用热压技术，将上述步骤三制备的纳米纤维复合膜进行热压，使得两面膜粘接更紧密；升温速度为5~15℃/min，热压的温度为70℃，热压的时间为5~30min，压力为2MPa。
步骤五，清洗晾干：将步骤四中制备的双面膜在水中清洗去除多余溶剂，放入烘箱中干燥，干燥温度为25~50℃，干燥后得到用于光热转换海水淡化、污水处理、加速晒盐的双面膜材料。
以上实施例，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，根据本发明的技术方案及其发明构思加以同等替换或改变，都应涵盖在本发明的保护范围之内。
