“…Previous studies by Okubo et al [26] concerning the morphology of micrometer-sized composite particles produced by polymerization of BMA within highly BMA-swollen PS particles resulted in spherical composite particles of size ca. 10 µm compared to initial diameter of the PS template microspheres of 1.77 µm.…”

“…The morphology of two-stage latex particles is controlled by two major factors concomitantly acting in the system [1][2][3][4][5]: thermodynamic factors that determine the equilibrium morphology of the final composite latex particles and kinetic factors that determine the ease with which the thermodynamically favored equilibrium morphology can be achieved. Seeded polymerization for the dispersion of highly monomer-swollen polymer particles gives composite polymer particles having a comparatively thermodynamically stable morphology [6]. On the other hand, seeded dispersion polymerization, in which almost all monomers and initiators exist in the medium, may result in kinetically controlled core-shell morphology in which layers of the second polymer accumulate in their order of formation, even if the morphology is unstable thermodynamically [7].…”

“…An alternative swelling method, called the dynamic swelling method, was developed by Okubo and coworkers. [20][21][22] According to this method, uniform PS template particles can be swollen enormously, and still maintain their uniformity, by the slow, continuous, dropwise addition of water into an ethanol/water medium containing the template particles and hydrophobic monomer(s) and initiator (e.g., styrene and benzoyl peroxide [BP]). Polymerization can then be performed, as previously described, by increasing the temperature.…”

Polychloromethylstyrene (PCMS) micrometer-sized particles of narrow size distribution were prepared by the dispersion polymerization of chloromethylstyrene in a mixture of ethanol and dimethyl sulfoxide. Micrometer-sized PCMS/poly(butyl methacrylate) hemispherical composite particles of narrow size distribution were prepared by a single-step swelling process of the uniform PCMS template particles with emulsion droplets of butyl methacrylate (BMA) containing benzoyl peroxide, followed by the polymerization of BMA at 738C within the swollen template particles. The effects of various polymerization parameters, for example, BMA volume, initiator type and concentration, and toluene as the swelling solvent, on the properties (size and size distribution, morphology, polymerization yield, and composition) of the hemispherical composite particles were elucidated.

Three-dimensional printing technology has fundamentally revolutionized the product development processes in several industries. Three-dimensional printing enables the creation of tailored prostheses and other medical equipment, anatomical models for surgical planning and training, and even innovative means of directly giving drugs to patients. Polymers and their composites have found broad usage in the healthcare business due to their many beneficial properties. As a result, the application of 3D printing technology in the medical area has transformed the design and manufacturing of medical devices and prosthetics. Polymers and their composites have become attractive materials in this industry because of their unique mechanical, thermal, electrical, and optical qualities. This review article presents a comprehensive analysis of the current state-of-the-art applications of polymer and its composites in the medical field using 3D printing technology. It covers the latest research developments in the design and manufacturing of patient-specific medical devices, prostheses, and anatomical models for surgical planning and training. The article also discusses the use of 3D printing technology for drug delivery systems (DDS) and tissue engineering. Various 3D printing techniques, such as stereolithography, fused deposition modeling (FDM), and selective laser sintering (SLS), are reviewed, along with their benefits and drawbacks. Legal and regulatory issues related to the use of 3D printing technology in the medical field are also addressed. The article concludes with an outlook on the future potential of polymer and its composites in 3D printing technology for the medical field. The research findings indicate that 3D printing technology has enormous potential to revolutionize the development and manufacture of medical devices, leading to improved patient outcomes and better healthcare services.
