The solid-like oil-in-water (O/W) emulsion can be classified into two types, gelator-induced gel and gelator-free glass, based on the requirement of gelator addition and solidification mechanisms. In this work, the O/W emulsion glass with scanty-water belonging to the gelator-free type was successfully fabricated through a low-energy process even when the content of aqueous surfactant solution was as low as 1 wt%. In an attempt to develop this scanty-water O/W glass, two newly designed approaches subject to mechanical agitation were proposed. The first approach of glass formation was induced by the growth of glass nuclei, which is similar to the mechanism of crystal growth. In the second approach, the water content in the emulsion was diluted by oil addition, leading to the direct transformation from emulsion to glass. Both approaches undergo a crossover associated with the jamming transition. According to rheological measurements, our emulsion glasses possess solid-like behaviors such as elastic modulus and yield stress. Moreover, the O/W glass with scanty-water can be strengthened by reducing the water content.

根据胶凝剂添加和固化机理的要求，固体状水包油（O / W）乳液可分为两种类型，胶凝剂诱发的凝胶和无胶凝剂的玻璃。在这项工作中，即使表面活性剂水溶液的含量低至1 wt％，也可以通过低能工艺成功地制造出属于无胶凝剂型的具有少量水的O / W乳状玻璃。为了开发这种稀水O / W玻璃，提出了两种新设计的机械搅拌方法。玻璃形成的第一种方法是由玻璃核的生长引起的，这与晶体生长的机制相似。在第二种方法中，乳液中的水分通过添加油来稀释，从而导致从乳液直接转变为玻璃。两种方法都经历了与干扰过渡相关的交叉。根据流变学测量，我们的乳胶玻璃具有类似固体的行为，例如弹性模量和屈服应力。此外，可以通过减少水含量来增强水少的O / W玻璃。
