Overall modification is the modification that occurs in both the interior and the surface of the polymer material. A feature of this kind of modification is that performance changes uniformly. Modification of polymer materials is mostly overall modification, such as filling modification, blending modification, crosslinking modification, morphology control modification, and so forth that were mentioned previously. 

Filling modification of polymer is the addition of solid additives with different composition and structure to the polymer matrix material to reduce costs or obviously change the performance of polymer products, which will improve the desired performance at the expense of other kinds of performance at the same time. Such an additive is known as a filler. Because these fillers are mostly inorganic powder, filling modification relates to performance difference and complementation of organic polymer and inorganic matter. This provides diverse areas of research and broad fields of application for filling modification. 

General Principles of Filling Modification of Polymer Materials... 

Therefore, in the practice of polymer filling modification, any extra effects of valuable performances of polymer materials must be prevented, and an integrated balance should be achieved among the contradictory effects. 

In the indirect method, surface-modified whiskers are filled into polymers to prepare composite materials and the surface modification effects of whiskers can be evaluated by studying characteristics of composites, such as mechanical, thermal, and electrical properties. This method is the most often used. 

In recent years, there has been a breakthrough in the manufacturing cost of potassium titanate whiskers, aluminum borate whiskers, and so forth. Meanwhile, inexpensive and high-quality inorganic whiskers such as calcium carbonate, calcium sulfate, and magnesium are successfully synthesized, which makes inorganic whiskers a new type of filling modification material of polymer materials. This field has become a research hotspot all over the world and reveals broad application and market prospects.
