There is increasing interest in the synthesis of golf ball-like particles. Most of the reports on golf ball-like particles have focused on polymer particles, while relatively few are concerned with inorganic particles. In this work, golf ball-like thiol-functionalized silica particles were synthesized for the first time by a one-step sol–gel reaction using 3-mercaptopropyl trimethoxysilane (MPTMS) and tetraethoxysilane (TEOS) as the precursors. The particle growth with time was monitored by SEM and a particle formation mechanism was proposed. The effects of different reaction parameters including the TEOS/MPTMS molar ratio, the NH₄OH concentration, and the stirring rate on the morphology and size of the golf ball-like organosilica particles were studied. Given that the thiol groups have versatile functionalities, golf ball-like thiol-functionalized silica particle is a useful model for academic studies.

一步合成高尔夫球状硫醇功能化二氧化硅颗粒。

人们对高尔夫球状颗粒的合成越来越感兴趣。大多数关于高尔夫球状颗粒的报道都集中在聚合物颗粒上，而相对较少涉及无机颗粒。在这项工作中，首次使用3-巯基丙基三甲氧基硅烷（MPTMS）和四乙氧基硅烷（TEOS）作为前体，通过一步溶胶-凝胶反应合成了高尔夫球状硫醇功能化二氧化硅颗粒。通过 SEM 监测颗粒随时间的生长，并提出了颗粒形成机制。研究了不同反应参数（包括TEOS/MPTMS摩尔比、NH ₄ OH浓度和搅拌速率）对高尔夫球状有机二氧化硅颗粒形貌和尺寸的影响。鉴于硫醇基团具有多种功能，高尔夫球状硫醇官能化二氧化硅颗粒是学术研究的有用模型。
