综述了一种特殊的充气聚合物材料：由聚合物基质和中空球形填料组成的复合聚合物泡沫塑料或球形塑料。综述内容包括：聚合物中空微球和大球的制备和性能；复合泡沫塑料形成的物理原理：流变学、表观密度的调节、空间因子和复合成分的堆积；形成的化学和技术原理；基于环氧、聚酯、苯酚、聚酰亚胺和其他树脂的复合泡沫塑料的制备；以及最新类型的泡沫塑料-预浸料、多相结构、弹性体和增强泡沫塑料。讨论了物理性质的特殊性和强度参数的计算方法。试图评估球体的大小和填充对主要物理性质的影响和贡献。概述了复合泡沫塑料的主要应用和发展趋势。
The review deals with a special kind of gas-filled polymeric materials: the syntactic polymer foams, or spheroplastics, consisting of a polymer matrix and a hollow spherical filler. The survey covers the following aspects: preparation and properties of polymeric hollow micro- and macrospheres; physical principles of syntactic foam formation: rheology, regulation of apparent density, space factor and packing of syntactic compositions; chemical and technological principles of formation; preparation of syntactic foams based on epoxy, polyester, phenol, polyimide, and other resins, as well as the newest types of foams — prepregs, poly-phase structures, elastomeric and reinforced foams. The specificity of physical properties and methods of calculation of strength parameters are discussed. Attempts are made to evaluate the effect and contribution of size and packing of spheres on the principal physical properties. The main applications and trends of syntactic foams are outlined.
