胶乳即橡胶粒子的水分散体系。不同种类胶乳的平均粒径可以从几十纳米到几百纳米,且粒径分布的均匀情况也有很大差异。胶乳粒子的形态及其粘连等情况也会对其物性产生很大的影响。因此,实现胶乳粒子形态的直接观察是很重要的。用电镜观察胶乳样品时,有两个问题是非常重要的。一 Latex latex rubber particles that the water dispersion system. The average particle size of different types of latex can be from tens of nanometers to several hundred nanometers, and the uniform distribution of particle size is also very different. The shape of latex particles and their adhesion will also have a great impact on their physical properties. Therefore, it is important to realize the direct observation of latex particle morphology. Two issues are important when looking at latex samples with electron microscopy. one
