After treatment with NaOH and ethanol, the crystallization degree of the nanocomposite film was greatly enhanced, which caused an evident improvement in its mechanical properties. This method provides a simple and green approach to enhance the mechanical properties of polymer-...
物理方法包括机械粉碎、蒸汽爆碎、微波辐射和超声波预处理;化学法一般采用酸、碱、次氯酸钠、臭氧等试剂进行预处理,其中以NaOH 和稀酸预处理研究较多;物理化学法包括蒸汽爆破和氨纤维爆破法;生物法是用白腐菌产生的酶类分解木质素。这些预处理方法各有其优缺点,今后的主要研究方向是继续探索反应条件温和、无有毒副产...

To find the volume/volume percentage (v/v%) of ethanol in the aqueous solution, we can follow these steps:1. Identify the given values: - Volume of ethanol (solute) = 20 ml - Total volume of the solution = 500 ml2.
b.扩散过程中吸收的热量<水合过程中放出的热摄,溶液温度升高,如:NaOH、浓硫酸溶解于水。 c.扩散过程中吸收的热量≈水合过程中放出的热量,溶液温度几乎不变,如:NaCl溶解于水。 常见冷冻混合物: 在生产、生活中常用冰作冷却剂,但冰只能提供 0℃左右的低温。一些医疗和研究单位常需要更低的温度,提供低温较方便的...
